I'm Syed Bilal Hassan Rizvi — a senior engineer with 7+ years building Flutter & Android apps, web platforms, and ML-powered products that real businesses run on.
About
Good software is invisible — it simply works, every day, for the people who depend on it.
I'm currently a Senior Software Engineer at Taptap Technologies, leading cross-functional engineering across mobile, backend, and data. My latest delivery: a five-product enterprise suite for the UK's second-largest van dealer, including an AI call-analysis engine and a marketing intelligence platform.
Alongside work, I'm completing a Master's in Data, Algorithms & Machine Intelligence at the University of Palermo — because the most useful ML is the kind that leaves the notebook and enters production.
