I help startups and enterprises build complete AI ecosystems by integrating Large Language Models (LLMs) into robust, production-grade backend architectures. Whether you are building an AI SaaS MVP from scratch or adding RAG-based intelligence to an existing platform, I deliver clean, maintainable, and secure code. What I bring to your project: 1. AI Integration: Expert in OpenAI (o1/GPT-4), Claude 3.5, and Gemini 2.0. I specialize in RAG (Retrieval-Augmented Generation) and AI Agent workflows using LangChain and CrewAI. 2. Backend Excellence: Scalable microservices built with FastAPI, Python, or NestJS. I focus on high-concurrency, security, and performance. 3. Vector Infrastructure: Implementation of Pinecone, Weaviate, or PGVector for efficient data retrieval. 4. SaaS Architecture: Multi-tenant database design, Stripe subscription logic, and RBAC (Role-Based Access Control). Why work with me? - Speed to MVP: I focus on getting your AI SaaS to market in 3–6 weeks without technical debt. - Product Thinking: I don't just follow tickets; I ask "Why?" to ensure the feature actually drives user value. - Security First: I ensure your AI integrations are prompt-injection resistant and GDPR/SOC2 compliant. TECHNICAL STACK: - AI & LLM: OpenAI API, LangChain, RAG, Prompt Engineering, Vector DBs (Pinecone) - Backend: Python (FastAPI, Django), Node.js (NestJS, Express), Go - Databases: PostgreSQL, MongoDB, Redis, Supabase - Cloud & DevOps: AWS (Lambda, ECS), Docker, GitHub Actions, Vercel - Integrations: Stripe, Auth0, Twilio, HubSpot, Slack API vähemmän

My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. vähemmän

I deliver complete operating systems that run your business on autopilot ⚙️—saving you 20+ hours/week and eliminating the need to hire multiple specialists. I'm the Systems Integrator who connects your Data, AI Models, and User Interface into one seamless machine 🤝 What I Build: 1. Full-Stack AI SaaS (Next.js + Supabase + Stripe) 💻 You have an AI idea. I turn it into a deployable product with: Role-based workspaces (Team/Personal accounts) 👥 Subscription tiers with usage limits 💳 Production-grade security (Auth, DB, Docker) 🔐 Proof: Deployed 3 SaaS apps serving 2,000+ active users 🚀 One processes 50K+ API requests/day with <200ms response time ⚡ 2. Advanced Web Scraping (When "Unscrapable" Isn't an Option) 🕵️♂️ I extract data from sites protected by Cloudflare, 2FA, and bot detection using Selenium-Stealth + Chrome DevTools Protocol. The Difference: I simulate genuine human behavior 👤 Your pipeline doesn't break when they update their defenses. Proof: Built scraping systems processing 50K+ records/day with zero downtime for 6+ months 📊 3. Computer Vision & Custom AI (PyTorch, YOLOv8, LangChain) 🤖 * Train custom YOLO models for defect detection * Build “Chat with your PDF” RAG systems 📄 * Deploy document intelligence APIs that parse layouts other tools can't 4. Workflow Automation (n8n + Python APIs) 🔄 I don’t just write backend services—I connect them to your daily tools (Slack, Sheets, CRMs) with visual dashboards your team can actually understand 📈 Why This Matters Your YOLO model is useless without FastAPI. Your scraper is useless without a database. Your automation is useless if it requires a developer to run it. I deliver the whole stack 🧩 Core Tools: Python (FastAPI, Selenium, PyTorch) 🐍 JavaScript (Next.js, React) ⚛️ Supabase, Docker, n8n 🛠️ Let’s build a system that works while you sleep 🌙 vähemmän
