Vishon Singh

Product-Driven Software Engineer

I build end-to-end products from real problems using data, simple architecture, and fast execution.

01.About Me

I'm a software engineer with experience at Amazon and Fasten Health, where I worked on distributed systems, billing integrations, and reporting pipelines.

I like turning messy data and unclear ideas into simple products. Outside work, I build tools like ApartmentIssues and FindReads as experiments in solving real-world problems with minimal tech.

My Approach

▹ Start with the real problem
▹ Build minimal end-to-end first
▹ Test with data + feedback
▹ Keep architecture simple
▹ Own every part of the stack
▹ Ship fast, iterate faster
