I'm a full-stack developer based in Dhaka, Bangladesh, specializing in production-ready web apps, SaaS products, and AI-powered features.
Stack: Next.js, React, TypeScript, Node.js, PostgreSQL, MongoDB, Redis, Docker, Paddle, and AI APIs like Google Gemini. I've independently built and launched a paid SaaS product and delivered apps for local clients.
I focus on clean architecture, secure integrations, and practical deployment — clarifying scope and acceptance criteria upfront so projects stay predictable.
Send me your requirements and I'll recommend the best implementation path.

FAQ
What kind of AI features can you integrate?
Chatbots, automation workflows, content generation, RAG/document search, and general LLM API integration (OpenAI, Claude, Gemini) into your existing web or mobile app.
Can you work with my existing codebase?
Yes — I review your repository, architecture, and existing patterns first, then integrate in a way that fits what's already there.
Do you offer AI model fine-tuning?
Yes, as a standalone add-on — it's not bundled into the base packages since Fiverr's own data shows that reduces buyer confidence, but I can scope it separately if your project needs it.
Will I receive the source code?
Yes, full source code is included in every package.
Is this suitable for production, or just a demo/MVP?
Production. I've built and shipped a live paid SaaS product with a real AI feature (Gemini-powered) in production, not just prototypes.
Do you sign NDAs?
Yes, happy to sign an NDA before discussing project details.
Can you fix or extend an app built with Lovable, Replit, Bolt, or similar tools?
Yes — see the No-Code App Fix-Up add-on. These tools accelerate first drafts but usually still need real engineering around auth, databases, and AI reliability.
Who pays for AI API usage costs?
You do — API costs (OpenAI, Gemini, etc.) run on your own account so you keep full ownership and control of usage/billing; I handle setup and integration, not the recurring API subscription.
