Senior Backend/Full-Stack Developer: Refactoring & Server Deployment for "Sakshyaam AI"

@kamran2012

Interesting project, I will tackle the OCR accuracy and video modules first. For tabular extraction, I will use Azure Document Intelligence's prebuilt layout model with custom post-processing — normalizing cell boundaries and merging split rows — to push accuracy past 90%. For video seeking, I will re-index keyframes with FFmpeg after processing so thumbnails and seek positions stay aligned. Questions: 1) Are the Charge Sheets primarily Hindi/English, and what format — scanned PDFs or images? 2) Is the video pipeline currently using FFmpeg directly or a wrapper library? Looking forward to discussing further. Best regards, Kamran

Hi Vishwanth, I understand you need a senior full-stack + DevOps engineer to stabilize and scale your case management & forensic system. Approach: 1️⃣ Tabular OCR (90%+ accuracy) • Use Azure Document Intelligence (Layout + Custom models) • Pre-process images (deskew, denoise, contrast) • Post-process tables via bounding boxes + validation (GSTIN, dates) • Confidence scoring + fallback reprocessing • Train models on real charge sheet samples 2️⃣ Video Seeking (FFmpeg) • Fix keyframe/GOP structure for accurate seeking • Re-encode to H.264 + faststart • Correct timestamp-based thumbnail generation • Sync backend seek logic with frontend playback 3️⃣ System & Security • Modular services (Node.js + Python) • AES-256 field-level encryption • RBAC + logs + credit system • Docker + CI/CD + SSL + OWASP hardening Timeline: Core fixes: 3–4 weeks Full scope: 6–8 weeks Availability: Ready to start Could you confirm: • Current OCR pipeline (Azure/custom?) • Video processing format/flow? Looking forward to collaborating. Kind regards, Team Pixxelu!

Your charge sheet fusion module will fail under concurrent user load if the data merging logic isn't wrapped in database transactions. Without proper isolation levels, you'll get duplicate entries or partial updates that corrupt the final output. Before restructuring your codebase, I need clarity on two things. First, what's your current database architecture - are you using PostgreSQL with proper indexing, or is this still on SQLite from the prototype phase? Second, what's the expected user concurrency for the admin dashboard - 10 simultaneous sessions or 100? This determines whether I architect for horizontal scaling now or phase it in later. Here's the architectural approach: - PYTHON + NODE.JS: Separate your AI processing layer (Python/FastAPI) from your web interface (Node/Express) using a message queue like RabbitMQ. This prevents AI inference delays from blocking user requests. - POSTGRESQL TRANSACTIONS: Refactor the charge sheet fusion logic to use ACID-compliant transactions with row-level locking. This eliminates race conditions when multiple users trigger merges simultaneously. - NGINX + SSL: Configure reverse proxy with rate limiting and automated Let's Encrypt renewal. I'll harden the Ubuntu server with fail2ban and implement SSH key-only authentication. - REACT ADMIN DASHBOARD: Build a real-time monitoring interface using WebSockets to stream logs from Winston/Bunyan. You'll see API response times, error rates, and user actions without refreshing. - MODULAR ARCHITECTURE: Implement a layered structure with separate directories for routes, controllers, services, and data access. I'll add .env management and Docker Compose for consistent deployments across environments. I've restructured 8 "messy" codebases in the past 3 years, including two AI projects that scaled from prototype to 50K users. I don't take on projects where the existing architecture is so broken it's cheaper to rebuild - let's schedule a 20-minute call where you walk me through the current file structure so I can give you an honest assessment of refactor vs. rewrite.

Hi there, I’ve reviewed your project and understand you’re in the critical final phase where Sakshyaam-AI needs to transition from a functional but unstructured build into a clean, scalable, production-ready system. The priority is not just fixing code but restructuring it into a maintainable architecture, resolving the charge sheet fusion logic, and ensuring a stable, secure deployment environment with full visibility through an admin dashboard and logging. I can audit and refactor your existing codebase into a modular, layered architecture that clearly separates AI logic, APIs, and data handling while enforcing clean conventions and documentation. I’ll resolve the charge sheet fusion module for accuracy and performance, then handle full server migration with proper environment setup, SSL, and security hardening. On top of that, I’ll build a responsive admin dashboard with centralized logging to monitor system health, user actions, and errors in real time, ensuring long-term maintainability and control. Let’s connect so I can review your current stack and codebase, share similar restructuring and DevOps work, and outline the most efficient path to stabilize and scale your platform.

@avinashdubeyg209

Noticed the emphasis on restructuring and moving Sakshyaam-AI to production. Just wrapped up a similar project where I built a RAG pipeline for a fintech client. They had similar requirements for code cleanup and server migration. For this, what's the current tech stack besides JavaScript and Python? Understanding this will help tailor an effective deployment plan. Can start today, let me know if you'd like a quick outline of how I'd approach the refactoring process.

Hi, As per my understanding: You already have a partially built case management & forensic system and now need an expert to stabilize, secure, and complete it. Key focus areas are improving OCR accuracy for legal documents, fixing video processing (seek/thumbnails), implementing strong encryption, refining architecture, and setting up a production-ready DevOps pipeline with RBAC, logs, and integrations. Implementation approach: For OCR (#1), I will enhance Azure Document Intelligence with custom model training, structured post-processing, and table parsing logic to achieve 90%+ accuracy. I’ll add validation layers and caching to reduce API cost. For Video (#5), I will fix FFmpeg seek issues using proper keyframe indexing and encoding flags, ensuring accurate thumbnails and smooth navigation. Overall, I’ll refactor backend (Python/Node), enforce AES-256 encryption, implement RBAC, and set up Dockerized deployment with CI/CD, SSL, and OWASP security hardening. Code will be modular, scalable, and production-ready. A few quick questions: 1. Do you already have labeled datasets for OCR training? 2. Current infra: AWS, Azure, or hybrid? 3. Preferred DB: PostgreSQL or MongoDB? 4. Any existing CI/CD pipeline in place? 5. Timeline expectation for full completion?

Hello, I’ve gone through your job description and understand that you’re looking for a senior full-stack developer to restructure your codebase, handle server migration, and build an admin dashboard with logging. With 5+ years of experience in full-stack development , I’ve delivered similar projects with a focus on clean architecture and scalability. What I can help you with: • Refactoring unstructured code into a scalable modular architecture • Fixing "charge sheet fusion" logic for accuracy and performance • Server migration, setup, and security hardening • Admin dashboard development with centralized logging Warm regards, Monica Bhatia

@techsty2014

I can help with this, I will audit your Sakshyaam-AI codebase, refactor it into a modular layered architecture separating AI logic, data access, and API layers, then migrate everything to your dedicated server with proper security hardening. I will also build the admin dashboard with centralized logging for user actions and system errors. For the charge sheet fusion module, I will isolate it into its own service layer with unit tests first — that way the logic fix is verified before the broader refactor touches anything around it. Questions: 1) What is the current tech stack — Python with a specific AI framework, or Node.js? 2) Is the dedicated server already provisioned, or do you need help selecting the setup? Let us discuss via chat. Best regards, Faizan

This is a high-sensitivity, production-critical system, so my approach will focus on accuracy, security, and stability—not quick patches. Task #1 – Tabular OCR Accuracy (90%+ Target) I’ll implement a hybrid pipeline: • Use Azure Document Intelligence (Layout + Custom Models) for structured extraction • Post-process with Python (Pandas + rule-based parsing) to reconstruct tables • Add validation layer (schema checks, row/column alignment correction) • Confidence scoring + fallback logic (reprocess low-confidence blocks) • Optional fine-tuning with labeled samples for your specific formats This ensures consistent accuracy across Charge Sheets, Case Diaries, and Remand Reports. Task #5 – Video Seeking (FFmpeg) Issue is likely due to encoding/indexing: • Re-encode videos with proper keyframe intervals (-g, -keyint_min) • Generate accurate timestamps + metadata during processing • Use FFmpeg + HLS/DASH for seekable streaming • Fix thumbnail sync using exact frame extraction (-ss pre/post seek handling) Additional Strengths • AES-256 field-level encryption + secure storage • RBAC + audit logs • DevOps (Docker, Nginx, SSL, CI/CD, OWASP hardening) I’ve worked on systems involving OCR pipelines, secure data handling, and media processing, where precision and compliance were critical. If you want this system production-ready—not fragile—we should execute this in structured phases. Best regards, Amaan Khan L. (CUBEMOONS PVT.)
