I am a backend-focused developer interested in building reliable APIs, backend systems, and developer tools.
My current focus is learning through real open-source work: understanding existing architecture, finding practical bugs, writing regression tests, fixing CI failures, and improving code through maintainer review.
I am especially interested in:
- Python backend engineering
- FastAPI and API design
- Async systems and state management
- Testing, CI, and reliability
- Framework internals
- AI-powered backend applications
- Building backend systems with clean architecture and maintainable APIs
- Contributing to production open-source projects
- Studying framework internals through real issues and pull requests
- Improving skills in distributed systems, cloud, and backend reliability
- Building and improving MoveSaathi
I have been contributing to Reflex, a Python framework for building full-stack web apps.
| Work | Area | Impact |
|---|---|---|
| PR #6830 | Backend state manager internals | Fixed shared asyncio.Lock behavior across memory, disk, and Redis state managers |
| Issue #6829 | Backend bug report | Reported state-manager lock isolation bug with a clear root cause |
| CI and review follow-up | Testing and maintainability | Fixed failing tests, added news fragment, and addressed test-isolation feedback |
- I prefer small, reviewable fixes with clear reasoning.
- I try to understand the system before changing code.
- I focus on regression tests when fixing bugs.
- I treat maintainer feedback as part of the engineering process.
