You will get a production-ready AI agent or RAG chatbot for your business data
Top Rated
Project details
You will get a production-ready AI agent or RAG chatbot built on your own data — deployed, tested, and working with real users, not a demo that dies in a notebook.
I'm a Top Rated Plus AI Engineer with 100% Job Success, 36 completed contracts, and 4,000+ hours on Upwork. I build LLM-powered systems end to end: RAG chatbots that answer accurately from your documents, websites, and databases (with citations, not hallucinations), and AI agents that connect to your tools — CRM, Slack, email, internal APIs — to automate real workflows.
What makes this different: I'm a backend and cloud engineer first. Your chatbot ships with the full production stack — FastAPI backend, vector database (Pinecone/pgvector), AWS deployment, monitoring, and error handling — so it scales instead of breaking the week after delivery.
Stack: Python, JavaScript, OpenAI GPT-4o, Anthropic Claude, LangChain, LangGraph, FastAPI, AWS.
Every package includes source code, deployment, and a handover walkthrough so your team owns the system. Not sure which package fits? Message me with what you're building and I'll tell you exactly what it needs — no copy-paste pitch.

Full-Stack Developer Needed for Luxury Vacation Rental Platform (Backend + CMS + Website)
Ali delivered our V1 website on a React/Next.js, Node/Express, MongoDB, and AWS stack. The final product is functional and live. Communication was generally responsive and he was open to feedback throughout the project. Would recommend.

Job Success
Ottawa, Canada - 8:21 pm local time
At American Airlines, I worked on the booking platform that moves millions of travelers across the US. At SolarWinds and Ericsson Canada, I built infrastructure and data pipelines at enterprise scale. Since then I've taken that same discipline into startups and product companies and building from zero, taking over broken codebases, and shipping things that stay shipped.
Production work I own today: a programmatic ad exchange with real-time bidding and Stripe Connect payouts, an AI voice agent on OpenAI Realtime hitting sub-35ms response handling live business calls with no human in the loop, a HIPAA-compliant healthcare platform with HL7 and FHIR integration, a real-time geospatial mobile app, and a fintech SaaS processing real transactions. All live. All mine to maintain.
Here is what I bring to your project:
Full stack engineering: React, Next.js 14/15, Node.js, NestJS, TypeScript, PostgreSQL, MongoDB, Prisma, Supabase, Redis, REST APIs, GraphQL. I have owned monorepos end to end, not just the frontend, not just the deploy pipeline, the whole thing. I can debug a React rendering bug in the morning and reason through a Postgres migration in the afternoon.
AI and automation: OpenAI API, Anthropic Claude, LangChain, RAG pipelines with vector retrieval and re-ranking, autonomous agents, multimodal systems, n8n workflow automation, Twilio voice and SMS. I build AI systems that run in production under real load, not just in a notebook. Claude Code and Cursor are open on my machine every day — I use them to move faster, not to ship code I don't understand.
Payments and billing: Stripe Connect, subscription billing, metered billing, trial-to-live transitions, webhook idempotency, failed payment recovery, multi-party payouts, proration logic. I have rebuilt broken billing systems mid-flight with active subscribers. This work touches real money and I treat it that way.
Backend infrastructure: NestJS microservices, AWS EC2, S3, RDS, Lambda, CloudFront, IAM, Docker, Railway, Vercel, CI/CD pipelines. I have run zero-downtime database migrations on live systems using expand/contract patterns with staged rollbacks not maintenance windows.
I work directly with founders, CTOs, and product leads. No agency, no middlemen, no hand-holding required. I read your codebase, understand the architecture, and start contributing in days. I make pragmatic decisions, flag risks early, and own my work until it is stable in production.
