Band

Lang

Backend developer with a strong focus on building secure and scalable APIs. Tech stack: Python (FastAPI), Redis, PostgreSQL, Docker, Git, Linux, C, x86-64 Assembly (wrote my own OS kernel from scratch). What I can do for you: Build a microservice from scratch (authentication, rate-limiting, real-time features and other things), Debug and optimize existing APIs, Set up Redis-based caching or rate-limiting, Integrate third-party services and payment gateways. Why me: I'm not just a "coder". I understand how systems work under the hood — from CPU interrupts to HTTP requests. When your API crashes at 3 AM, I don't guess. I debug. Proof of work: My own OS kernel (x86-64 Assembly + C): https://github.com/band-lang/axiom, Auth microservice (FastAPI + Redis + PostgreSQL + Opaque tokens for auth): https://github.com/band-lang/auth-service. Open to both short-term and maybe long-term projects. Let's build something solid.
