Backend-focused Software Developer with 6+ years of experience in backend development, REST APIs, and application development using Python, FastAPI, PHP, Laravel, MySQL, and PostgreSQL. Experienced in building scalable APIs, implementing business logic, integrating third-party services, and developing real-time applications using WebSockets.

Hands-on experience with AI-powered applications using RAG, LLMs, Ollama, embeddings, and vector databases. I also use Claude and AI-assisted development tools for requirement analysis, implementation, code review, testing, and debugging. Strong in problem-solving, technical ownership, client communication, and delivering reliable solutions. Interested in Backend Engineering, Python/FastAPI, AI-powered applications, and Agentic AI development.
