I build SaaS platforms, ERPs, and AI-powered products end to end.
React and Next.js up front, Node.js, NestJS, and PostgreSQL underneath, LLMs wired into the workflow.
- Own the whole build. 6+ years shipping production code and 30+ client projects, from database schema and API design to the UI, deployment, and support after launch.
- AI inside the workflow, not bolted on. Multi-model LLM pipelines, RAG over private data, tool-using agents, and n8n automation, with guardrails and safety checks that sit outside the model.
- Products that carry real operations. SaaS platforms, distribution ERPs, and AI products with role-based access, payments, async job queues, strict TypeScript, CI, and error monitoring.
- Remote by default. Working with founders and teams across the US, Canada, the UK, Europe, Australia, and the Gulf over email, Slack, Discord, WhatsApp, and video call.

| Project | Problem Solved / Impact | Stack |
|---|---|---|
| AI ERP for Industrial Distribution Case study |
Runs a lubricants distributor on one system: storefront, staff console, and API. Reorder points raise purchase orders automatically, every transaction posts its own double-entry journal, and staff ask an AI chatbot about live stock. In production. | NestJS, Next.js, TypeScript, PostgreSQL, Prisma, Stripe, OpenAI API |
| AI Learning Content Platform Case study · Live |
Turns one recorded talk into a full mini-course: transcript, summary, quizzes, and exercises. AI work runs as queued async jobs with realtime status, moderation, and guardrails on every response. | Next.js, PostgreSQL, Prisma, AWS Bedrock (Claude), Transcribe, SQS, Pusher, Stripe |
| AI Pediatric Triage Platform Case study · Live |
Parents describe symptoms in plain language; a router model hands off to specialist triage, advisor, and explainer models, and doctors receive structured FHIR records. A keyword safety net outside the model can force urgent triage. | Next.js, TypeScript, Node.js, FHIR, OpenAI API, AWS Bedrock |
| Filely Toolbox Repo · Live · Case study |
Solo-built SaaS replacing a dozen single-purpose converter sites: 250+ image, PDF, video, and file tools plus AI writing and chat behind one account. | Next.js, TypeScript, Prisma, NextAuth, FFmpeg, sharp, OpenAI API, Gemini, Hugging Face |
| DevMatch Repo |
Swipe-to-connect network for developers with real-time chat, chat history, last-seen status, instant email on connection requests, and a daily reminder cron. | React, Redux Toolkit, Node.js, Express, MongoDB, Socket.io, AWS SES |
| CartWave Repo · API · Live |
Full e-commerce flow: search with autosuggest, filtering and sorting, pagination and infinite scroll, validated forms, and JWT auth on a separate REST backend. | React, Node.js, Express, MongoDB, JWT, Zod |
| CinemaGPT Repo |
Replaces endless scrolling with a prompt: describe a mood or genre and get a curated list of films back. | React, Redux Toolkit, Tailwind CSS, Firebase, OpenAI API |
