ABOUT ZAFAR HASSAN

I’m an Associate Technical Lead and Senior Backend Engineer with 8+ years of experience building, scaling, and owning backend systems in production.My core expertise is in Python-based backend development, working across frameworks like Django, Flask, and FastAPI, and designing cloud-native systems that are reliable, scalable, and maintainable.At Appinventiv, I lead backend development for large-scale platforms, most notably Hero FinCorp, where I’ve owned systems serving high traffic under strict SLAs. My role spans end-to-end delivery — from understanding business requirements and designing backend solutions to leading a team of engineers, managing deployments, and ensuring production stability.I’ve led and mentored teams of ~10 engineers, handled P0/P1 incidents with detailed RCA, and driven performance and reliability improvements through database and API optimizations. I also contribute to technical audits, code reviews, and effort estimation during project acquisition phases.Previously, I’ve worked on high-impact backend systems at Classplus and TradeIndia, including real-time notification engines, chat systems, large-scale data migrations, and platform modernization initiatives.I enjoy working on backend architecture, scalability challenges, and systems that operate at scale — and I value clean code, ownership, and strong collaboration between engineering and business teams.
