Summary
I’m a backend developer who enjoys turning complex ideas into working backend systems. I mostly work with
Python, FastAPI, SQLAlchemy, and Docker to build APIs that are fast, clean, and easy to maintain. I care a
lot about writing good async code, using DDD when it makes sense, and keeping things simple but solid. My
focus is always on building solutions that support real business needs and scale well as the product grows.
