INTRODUCTION
Overview.
From software developer to senior technical architect, my journey in the tech realm has been expansive.
Specializing in Python and backend development, I've designed full-stack applications using tools like Angular, Svelte, and FastAPI, and scaled them on platforms like AWS. Beyond web, my Android app boasts 300k+ Play Store downloads and my Progressive Web Apps span various platforms.
Currently, I'm deeply involved in a blossoming startup and advise a major US FinTech bank.
