# Hi, I'm Ashok Hake 👋

Software Engineer focused on **backend systems, distributed systems, AI applications, and scalable software architecture**.

I primarily build with **Python, FastAPI, PostgreSQL, Redis, Docker, AWS, and React**, with an emphasis on modular design, reliability, observability, and production-oriented engineering.
