We are developing an existing software platform and need a freelancer to build a simple, reliable automated organization intake system. This is not a request to rebuild our existing backend or business logic. Your task is limited to creating the intake layer that collects structured information and documents from a client organization and hands them over to our existing system in a predictable format. The intake should allow a user to: enter basic organization details; provide a Polish KRS registration number where applicable; complete a structured questionnaire about the organization, its activities, areas of operation, experience, resources, team and other relevant information; upload the organization’s statute / governing document as PDF; upload optional additional documents; submit everything as one complete intake package. The output must follow a predefined structured data contract called ORGANIZATION_INTAKE_V1. This is only an internal technical name and does not affect the implementation. We will provide the exact schema before development. The solution should include: a clean and simple web form; required-field validation; KRS format validation; secure document uploads; deterministic submission IDs; structured JSON output; predictable file organization/storage; webhook or API handoff to our existing system; compatibility with n8n workflows; clear success and error states; protection against accidental duplicate submissions where appropriate; basic logging/audit information; simple technical documentation. We are open to a pragmatic solution using n8n, low-code/no-code tools, a lightweight frontend, or another maintainable approach. We do not need a large custom web application. Reliability, simplicity and maintainability are more important than visual complexity. Important constraints: Do not redesign our existing database unless explicitly agreed. Do not modify our existing analytical or business logic. Do not add AI interpretation of uploaded documents or questionnaire answers. Do not infer information that the user did not provide. The intake component should remain independent from the rest of the analytical system. The final input/output contract must be deterministic and documented. Intended flow: User → Intake Form → Validation → File Uploads → Structured Intake Package → Webhook/API → n8n / Existing Backend We already have an existing backend, database, n8n environment and technical documentation. The selected freelancer will receive the relevant architecture information, exact input/output contract and example payloads. In your proposal, please briefly explain: how you would implement this; which technologies you would use; your estimated delivery time. We are looking for someone who can deliver a small, production-oriented component that integrates cleanly with an existing system, rather than redesigning the entire platform.

I’d implement this as a lightweight intake layer with a clean form, strict field validation, secure PDF/document uploads, and a deterministic JSON payload mapped exactly to your ORGANIZATION_INTAKE_V1 schema. The handoff can be done via webhook/API in a way that stays independent from your existing backend logic and works cleanly with n8n. I understand this is a production-oriented integration piece, not a full app rebuild, and I can keep it simple, reliable, and documented. Happy to review your payload examples and architecture notes through the platform before starting.

Hi, This is a straightforward intake system feeding structured data to your existing backend via a webhook, with file handling and validation as the core concerns. The form needs strict KRS validation, secure file uploads, and a deterministic JSON payload matching ORGANIZATION_INTAKE_V1. I’d build a lightweight single-page app for the form, using a minimal backend (likely Node.js/Express or Python FastAPI) to handle validation, generate submission IDs, and forward the payload to your webhook. Files would route through a storage service (S3 or similar) with predictable paths, while the backend keeps a simple log of submission attempts. n8n integration means the webhook just needs to be idempotent and return a clear success/error response. The tricky part isn’t the UI—it’s ensuring the JSON schema stays in sync with ORGANIZATION_INTAKE_V1 and handling upload retries or duplicate prevention cleanly. I’d lock the schema early and add basic rate limiting on the submission endpoint. The biggest unknowns are the exact file size limits, allowed document types, and whether KRS validation can be done client-side or needs backend confirmation. We’d clarify those before writing code. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

Hello, I can build this as a small, production-oriented intake component without touching your existing analytical or business logic. Implementation Clean responsive intake form for organization details and questionnaire sections. KRS registration-number format validation. Server-side required-field and payload validation. Secure PDF/document uploads with file-type and size restrictions. Deterministic submission IDs and predictable file storage structure. Structured JSON generated strictly according to your provided ORGANIZATION_INTAKE_V1 schema. Webhook/API handoff compatible with your existing n8n workflows. Duplicate-submission protection using an appropriate idempotency mechanism. Basic audit/logging information for troubleshooting and traceability. Clear success, validation-error, and submission-failure states. Technical documentation covering configuration, payload structure, storage, webhook integration, and troubleshooting. I will not redesign your database, modify business/analytical logic, add AI interpretation, or infer missing information. The component will simply collect, validate, package, and reliably hand over exactly what the user provides. The key priority will be a deterministic contract and reliable handoff, so the existing system receives every intake package in exactly the expected format. I’m ready to start once you provide the ORGANIZATION_INTAKE_V1 specification. Best regards ADEEL

I can help you build this intake layer as a clean, independent component that hands off to your existing system without touching your core logic. Implementation approach: The core problem is deterministic handoff, not UI complexity. I'd build a lightweight frontend (Vue or plain HTML/JS) that collects the form data and files, validates against the ORGANIZATION_INTAKE_V1 contract, and posts to an n8n webhook endpoint. n8n handles file storage, generates the submission ID, and forwards the structured package to your backend.

Your scope is clear, and that helps a lot here. I would build a minimal frontend intake form, add required-field plus KRS validation, organize uploads securely, generate deterministic submission IDs, and pass the final structured package to your existing system through webhook/API for n8n compatibility. I would keep the component isolated from your database/business logic and provide simple technical documentation at the end. This sounds like a good fit for a maintainable low-code/lightweight implementation.

Hi! I understand this is not a backend rebuild — you need a lightweight, production-ready intake layer that reliably collects organization data and documents, validates everything, and passes a deterministic package to your existing system. ++ What I’ll build: → Clean responsive intake form with required-field & Polish KRS validation → Secure PDF/document uploads with predictable file organization → Deterministic submission ID + duplicate-submission protection → Structured ORGANIZATION_INTAKE_V1 JSON output exactly matching your schema → Webhook/API handoff to your existing backend and n8n workflows → Clear success/error states with basic audit logging → Independent architecture with no changes to your database or business logic → Technical documentation covering setup, payloads, storage and integration Recommended approach: Lightweight frontend + backend/API layer with n8n handling workflow orchestration where appropriate. This keeps the component simple, maintainable and easy to extend without introducing unnecessary complexity. I’ll first review your existing architecture, schema and example payloads, then implement and test the complete flow: Form → Validation → Uploads → Intake Package → API/Webhook → n8n. If you share the existing documentation and ORGANIZATION_INTAKE_V1 contract, I can quickly confirm the implementation plan and get started. - Abhishek

Hello, I understand that you are specifically looking for someone who has already built an AI music-generation platform, and that demonstrating relevant work is a requirement. I have experience with AI-powered web applications, audio workflows, API integrations, backend systems, and responsive application development. I can work on a platform with the architecture required for music generation, including generation requests, audio processing, user accounts, generation history, downloads, libraries, and subscription/usage controls. If you are open to discussing the implementation, I can first review the exact Suno feature set you require and propose a practical architecture for the web and mobile applications, including the AI/audio backend, storage, authentication, generation queue, and API layer. I would also recommend defining the MVP and generation infrastructure carefully before development, because reproducing the full functionality of a mature platform like Suno is significantly larger than a typical $250–$750 project. I am available to discuss the technical requirements if the budget and scope can be aligned. Thank you. RAHEEL

100% doable. Clean scope, staying inside the intake layer only makes sense. Built an AI intake system for a US client, 50+ intakes processed in the first week live, structured JSON output feeding a downstream system. How I'd build it: a lightweight form frontend, validation on required fields and KRS format, secure uploads, all packaged into a deterministic JSON contract. Webhook handoff straight into your n8n environment once ORGANIZATION_INTAKE_V1 is confirmed. No AI interpretation, no inference, exactly what you specified. Tech: simple frontend, n8n for validation and orchestration, structured file storage, deterministic submission IDs to prevent duplicates. Estimated delivery: about one week once I have the exact schema and example payloads. Feel free to DM me for case studies. Or check the projects on my profile. Let's do it.

I’ve built intake forms with KRS validation and PDF uploads before, so this is right in my wheelhouse. I’ll implement a lightweight React frontend with React Hook Form for validation, including a custom KRS regex validator, and integrate Cloudflare R2 for secure file storage with deterministic UUID filenames. The backend will be a minimal Node.js/Express service generating ORGANIZATION_INTAKE_V1 JSON payloads and dispatching them via webhook to your n8n endpoint, with duplicate submission checks using Redis-backed request deduplication. Logs will stream to Winston to stdout for audit trails. No database changes—just a stateless service with environment variables for n8n webhook URL and R2 credentials. Deployment will be a single Docker image to your existing cluster. Thanks, Andrii.

Hi, I'm Leo Sarmiento, a developer specializing in intake forms and integration with existing systems via API and n8n, with over 10 years of experience in systems integration. The form itself is straightforward; what defines this component, and what you flag as the priority, is delivery reliability: that the intake package reaches your system following the exact ORGANIZATION_INTAKE_V1 contract, with deterministic IDs, protection against duplicate submissions, and clear success and error states. I build it as an independent component, without touching your backend, database or business logic, and with no AI interpretation, respecting your constraints. I propose a lightweight frontend for the form — with required-field and KRS-format validation, and secure document upload — that delivers the structured JSON to your n8n environment via webhook, with basic audit logging and documentation of the contract. It's the pragmatic, maintainable approach you're looking for, without an unnecessary custom app.

hey! The part that needs the most care here is keeping the intake fully deterministic — same input always producing the same structured output, no AI interpretation, no inferred fields, since that's what your existing system depends on downstream. I'd build the form and validation layer first, then wire the n8n handoff once the structured output matches your exact contract. Do you have the ORGANIZATION_INTAKE_V1 schema ready to share, or does that come after we're aligned on approach? 5+ years shipping full systems — backend logic, database design, frontend delivery. Clients who come back for the next phase. A crypto dashboard with live exchange data, a financial learning platform with Telegram bot integration, an Odoo-based e-commerce site, and AI agent migration delivered to production with zero revisions. From schema to deployment, I own it end-to-end.

Hi — this is a good fit for a lightweight, production-focused intake layer rather than a large custom application. I’d build a clean form with validation, secure PDF/document uploads, deterministic submission IDs, structured JSON generation, and a webhook/API handoff to your existing backend or n8n workflow. I’d keep the component completely independent from your existing business logic and follow the ORGANIZATION_INTAKE_V1 contract exactly, with basic logging, duplicate protection, and clear documentation. I’d suggest a lightweight frontend + API backend, with n8n handling the workflow integration where appropriate. Two quick questions: Is the ORGANIZATION_INTAKE_V1 schema already finalized? Do you prefer the intake hosted within your existing infrastructure or as a separate service? Estimated delivery: 2–4 days after receiving the technical documentation. Shakila Naz

Hi, your intake flow is clear: collect organization data, validate it, store files predictably, and hand off a deterministic package to your existing backend and n8n setup. I’d build this as a lean intake layer rather than a new application. For the form and validation, I’d use a lightweight frontend with server-side checks, including KRS format rules, required fields, and duplicate-submission protection. For uploads, I’d keep statute PDFs and optional documents in secure storage with consistent naming and metadata. The final submission would generate a stable ID, structured JSON matching ORGANIZATION_INTAKE_V1, and a clean webhook/API payload for your current system. I’ve delivered similar workflow-driven intake components with form validation, file handling, and n8n integrations. My focus would be reliability, simple maintenance, and clean handoff. I can review your schema and architecture details and deliver this in about 1-2 weeks. Best regards, Gabriel

==== Hi-Truong Here ==== "ORGANIZATION INTAKE SYSTEM" — you need a small reliable intake layer that validates data, stores documents and hands one clean package to n8n. I’d use a lightweight form with server-side validation, deterministic submission IDs and controlled PDF uploads, then send the exact ORGANIZATION_INTAKE_V1 payload through a webhook. Duplicate protection and audit logging would sit at the intake boundary, keeping your existing backend and business logic untouched. Is the existing n8n webhook/API contract already defined, and where should uploaded documents be stored before the package is handed over?
