Hüseyin Tunay Çelik, software engineer in Wrocław: full-stack, cloud and AI engineering

Portfolio: huseyintunaycelik.xyz LinkedIn: huseyin-tunay-celik Email: h.tunay.celik@gmail.com Oracle Cloud Infrastructure 2025 Certified Foundations Associate

I build web, mobile and desktop software end to end: the React screen, the API, the database and the cloud it runs on. I use LLMs as engineering tools every day, wiring agents into build, review and bug-hunting workflows, and I send the bugs I find to the projects that own them. Final-year Computer Science student at WSB Merito University Wrocław (B.Eng., Feb 2027).

Thesis

Automated incident response under Zero Trust: MTTR reduction in Microsoft Azure IaaS · B.Eng., defence Feb 2027

  • An SSH brute-force against a monitored host is caught by a Sentinel KQL rule and blocked by a Logic App, with no human in the loop.
  • Mean Time to Respond is measured over repeated scripted trials and split into ingestion, detection and response latency.
  • The whole lab is code: seven Terraform modules, one-command deploy and teardown, least-privilege identities, CI on every PR.

How I work

  • One change, one pull request, small enough to review in one sitting.

  • Every bug fix ships with the test that would have caught it.

  • LLMs speed me up; review and tests decide what ships.
