The Byline

Haldad Almi. Backend, Data, and Full-stack.

I build backends, data pipelines, and SaaS that stay in production. Open for one more contract. Async. Weekday replies in 24h.

Start a brief Read the archive LinkedIn

A system you can build with.

Three non-negotiables in every service I ship.

§ 01

TYPED EVERYWHERE.

Every function signed. Every payload schema-checked. Validated at boot, not at 3AM.

§ 02

SHIPS ON SCHEDULE.

Idempotent jobs, retries with intent, dashboards that actually mean something.

§ 03

ONE SIGNATURE.

Backend, data, automation, or full-stack. Same discipline across every lane.

I don't do buzzwords.
I don't do fluff UI.
I ship every line like it has something to say.
