About me
I am a Full Stack AI & Python Backend Developer with 8+ years of experience building scalable web applications, SaaS platforms, and AI-powered systems. I specialize in backend engineering using Python (Django, FastAPI), Node.js, and REST APIs, with strong expertise in AI/ML integrations and LLM-based applications.
I design and build production-ready systems including multi-tenant SaaS platforms, automation pipelines, and intelligent AI agents using OpenAI, LangChain, and related frameworks. My focus is on clean architecture, scalability, and performance for high-traffic applications.
Core expertise includes backend API development, database design (PostgreSQL, MongoDB), cloud deployment (AWS, Docker), and secure authentication systems. I also build AI workflows, RAG pipelines, and data-driven applications for fintech, healthcare, and enterprise use cases.
I deliver reliable, maintainable, and scalable solutions from MVP to production, ensuring long-term stability and business growth.
