I've built production-focused Python backends for Phlex Payment Ltd, including RESTful Django APIs, JWT authentication, optimized SQL queries, and third-party integrations.

For BunkSpace, I architected a multi-tenant SaaS backend for hostel operations, powering room allocation, bed tracking, bookings, and role-based access while protecting tenant data isolation. I reduced new-hostel onboarding from 30 seconds to near instant and brought setup time under 500ms through background processing and architecture improvements.

I built BurstGuard as a distributed rate-limiting service with FastAPI, Redis, atomic Lua scripts, and configurable sliding-window and token-bucket algorithms. Its tenant-isolated rules, API-key authentication, cache-aside design, and failure-mode testing support reliable operation under concurrent load.

I'm also building an AI-powered student helpdesk with FastAPI, React, Redis queues, and SQLAlchemy, using an LLM for ticket classification, reply polishing, and summaries. I enjoy solving concurrency, data isolation, and reliable-system-design challenges, and I lead backend workshops and mentor developers through Google Developer Group NAU.
