I build systems thatmove real data —and ship.
Lead Software Engineer at QAF Lab. Five years of production SaaS and large-scale pipelines — now studying AI & Data Science, moving toward machine learning engineering.
I grew up in Mosul, where I learned that good software isn't about clever code — it's about people trusting the thing you built. That belief shaped everything since: the systems I ship, the engineers I mentor, and the community I started at home.
Currently leading engineering at QAF Lab and finishing an MSc in Artificial Intelligence & Data Science in Istanbul. Open to machine learning engineering roles, remote or Istanbul.
The journey
Mosul → Istanbul
2016 – 2020
BSc Software Engineering, Mosul University
Started engineering in a city rebuilding itself. Wrote my first production code part-time at QAF Lab while still studying.
2021
Teaching what I know
Trained two full-stack bootcamp cohorts at FikraSpace, then kept going: mentoring interns is still the part of the job I protect.
2023
Founding Tech Hub Community
Started Mosul's first developer community so the next cohort would not have to learn alone. Now 200+ members and growing.
Feb 2026 – Now
MSc Artificial Intelligence & Data Science, Istanbul Aydin University
Studying machine learning, deep learning, and big data alongside full-time engineering. The next chapter: machine learning engineering.
