PakistanWhat I'm looking for
I’m a Senior Software Engineer with 3+ years of experience building scalable SaaS platforms, REST APIs, and full stack web applications. I focus on backend and full stack development using Python, FastAPI, React, PostgreSQL, and cloud technologies.
In my current role, I develop scalable backend services for an AI powered PropTech SaaS platform, supporting 1M+ residential units and 8.7M+ renter engagements. I’ve designed and optimized REST APIs and GraphQL APIs, reducing API latency by ~30%.
I’m hands-on with performance and reliability: optimizing PostgreSQL/MongoDB queries, implementing Redis caching, and using asynchronous processing to improve scalability and system efficiency. I also collaborate with distributed engineering teams in a remote asynchronous environment.
Previously, I built and enhanced SaaS products like a booking and business management platform for 6,500+ businesses, contributed to microservices and monolith architectures, and supported systems like an LMS. I also delivered a production-grade URL shortener with authentication, analytics, caching, rate limiting, and background processing.
