Subrata Choudhury
Software Engineer
I'm a full-stack engineer with roots in electrical engineering, building reliable systems for real people: public platforms, health records, and tools that quietly run in the background and just work.
I care about clear architecture, honest documentation, and clear communication with stakeholders, even under pressure. I like taking messy, high-stakes problems and turning them into simple, dependable software.
