Full-stack developerBrooklyn, New York

I build useful software from the system outward.

I’m Shmuel Leider. I turn complex workflows into clear, durable products—across applied AI, the web, and developer tooling.

Selected work / 2024—Now

Built to be used.

Projects where product thinking, technical depth, and practical utility meet.

The throughline

Curious enough to explore. Disciplined enough to finish.

01

Product-minded

I start with the person and the workflow, then choose the technology that makes the experience simpler.

02

Systems-comfortable

Interfaces, APIs, data models, background jobs, security, and deployment all belong to the same product.

03

Always learning

My work moves between TypeScript, C#, Rust, AI, and the web—guided by a genuine habit of building to understand.
