About me
I'm Morteza SeyyedAghaei. Most of my time goes to systems that have to stay alive.
I started in backend and grew into service architecture, networking, and ops. I like understanding a problem at the root, then shaping layers so the team can move fast and the system still holds in production.
Sometimes I stay in the backend. Sometimes I take a product all the way. The test is simple: the user shouldn't feel the complexity — they should feel that it works.
03
The path so far
Where I learned how tightly scale, cost, and reliability are tied together.
Reveak
Backend & DevOps
2021 — Present
Remote
A platform that had to connect more and break less. I automated server provisioning, improved how clients find healthy paths, and moved infrastructure somewhere cheaper and clearer — so the service could breathe under real traffic. I've worked on an app with hundreds of thousands of active users, where small details decide whether nights stay quiet.

Backend developer
2018 — 2021
Isfahan
At Arvin I learned to shape backends so frontend and other teams aren't blocked. Migrating to NestJS, breaking a monolith into smaller services, mentoring juniors — more about building a foundation people could stay on than shipping one feature.

Where it started
2017 — 2018
Remote
My first serious work: bots people actually used, and protected playback for publishers who cared about copies. I still like that feeling — building something someone leans on every day.

Let's talk
Collaboration, consulting, or a sharp technical chat.
I usually reply quickly — especially when the problem is clear.
