Top Rated full-stack AI engineer (68 jobs, 100% JSS, 2,000+ hours on Upwork) with 6+ years building production AI systems for manufacturing, FMCG, and operations clients. I ship full SaaS products end-to-end — backend, frontend, AI features, deployment — not prototypes. I build the whole thing. I am a full-stack AI engineer with 6+ years of real business experience inside manufacturing, FMCG, and operations at Coca-Cola, Singer Bangladesh (Arçelik), Walton Hi-Tech. I have been on the client side of broken tools and bad data. Now I build the systems I wished existed. What makes me different from most full-stack freelancers: I can ship your React frontend, wire it to a FastAPI backend, connect it to PostgreSQL, add an AI agent or LLM feature, deploy it to AWS or Vercel — and I understand the business problem well enough to tell you when you are overbuilding. → SAAS MVP DEVELOPMENT This is my primary focus. If you are a founder who needs a working product in 2–4 weeks, this is what I deliver: → React / Next.js frontends — clean, responsive UI built for real users, not just demos. Tailwind CSS, component libraries, smooth UX. → FastAPI or Node.js backends — REST APIs with proper auth (JWT/OAuth), rate limiting, error handling, and documentation your team can actually use → Database design — PostgreSQL with a schema that won’t break when you hit 10,000 users. Migrations, indexing, query optimization. → Full deployment — Vercel for frontend, AWS EC2 or Railway for backend, environment configs, CI/CD with GitHub Actions. You get a live URL, not a zip file. → Stripe integration — subscription billing, usage metering, webhook handling, customer portal. Revenue from day one. → Auth systems — user registration, login, roles and permissions, password reset, email verification. Done properly, not hacked together. → AI & AGENTIC FEATURES FOR YOUR SAAS Most SaaS products in 2025 need at least one AI feature. I build them as production-ready components, not demos: → AI agents built with LangChain and LangGraph — autonomous workflows that research, extract, decide, and deliver structured outputs inside your product → RAG document systems — users upload files, ask questions, get answers with citations. Customer support, internal knowledge bases, legal document review. → LLM-powered data extraction — turn unstructured inputs (emails, PDFs, forms) into clean structured data your database can store → Automation pipelines — Airflow or Celery workers that run background jobs, send alerts, process queues, and keep your product running while nobody is watching → DATA & ANALYTICS LAYER → Power BI and Looker dashboards embedded in your product or delivered standalone — connected to live data, auto-refreshing, built for decision-making not decoration → ETL pipelines — multi-source data ingestion into PostgreSQL or data warehouses, replacing manual work permanently → ML prediction APIs — demand forecasting, churn scoring, recommendation engines — FastAPI endpoints your product can call in real time WHO I WORK WITH Founders building a SaaS MVP who need one engineer who can own the full stack — frontend, backend, AI, and deployment — without managing 4 different freelancers. Startups that have a working product but need to add AI features, improve performance, or fix the architecture before scaling. Operations and manufacturing businesses that need internal tools, dashboards, or automation systems built properly. Small teams where budget matters — you need someone who makes good decisions independently, not someone who needs constant direction. WHAT I HAVE DELIVERED ✓ Full-stack SaaS starter — Next.js frontend, FastAPI backend, PostgreSQL, JWT auth, Stripe billing hooks, rate limiting, deployed on AWS. Used as a base for client products. ✓ RAG document assistant — React UI, FastAPI backend, LangChain + ChromaDB pipeline, deployed on Vercel + EC2. Users upload PDFs, ask questions, get cited answers. ✓ LLM automation agent — searches the web, reads documents, queries a database, writes structured reports to Slack. Replaced 3 hours of manual work per week. ✓ Commercial analytics at Coca-Cola Icecek — sales data systems driving strategic decisions in a high-volume FMCG environment ✓ Quality data systems at Singer Bangladesh
