Sometimes you don't need a whole team — you need one experienced builder who can take an idea from zero to a working, deployed product. That's something I genuinely enjoy and have done repeatedly on my own.

Products I've built solo

• ChatExpense — an AI-powered expense tracker (Django, DRF, PostgreSQL, OpenAI, LangGraph); grew to 1300+ registered users with a Google Play app.
• ScanFixNow — QR-code-based maintenance incident logging for appliances and installations.
• stocksurferbd — a published Python library for Dhaka & Chittagong stock-exchange data.
• Wapptel — a WhatsApp marketing-automation platform.

I cover the full stack: backend and APIs, AI/LLM features, database design, and cloud deployment (Docker, AWS, Railway). If you have an MVP to validate quickly, I can help you get it in front of real users. See the Projects section for more.
