Software Engineer

Zayn Harrow

I build web apps, APIs, and the tooling around them, and take ownership of a problem end to end, from product to infrastructure.

Services

Product Engineering

New software built from the ground up, and existing codebases extended, repaired, and made faster, across the full stack.

Applied AI

Internal workflows and manual processes automated with language models, from intake and triage to drafting and review.

Infrastructure

Servers, databases, and deploy pipelines set up to stay quiet and dependable as traffic grows.

Developer Tooling

Internal CLIs, automation scripts, and continuous integration that turn the slow, repeated parts of a workflow into a single command.

I take on a couple of projects at a time. If you have something that needs building, or rebuilding, I’d like to hear about it.
