About
I've been building software with C# and .NET since 2008. Since 2013 most of my work has been in travel booking: systems that bring flight, hotel and car-rental inventory from many suppliers into a single search-and-booking flow. Today I lead a 10-person team at Tatil Sepeti, where I still write code and run the code review and automated quality gates (SonarQube, SAST, OWASP Top 10) the team ships through. Recently I've been building AI agents with Claude Code, including a RAG-based internal knowledge assistant. I hold an MSc in Computer Engineering (Cybersecurity). This site is where I write up what I learn about AI engineering.
Timeline
AI engineering
Studying AI engineering in depth (retrieval, evaluation, agents), focused on where it meets my security background: testing whether tool-using AI agents can be manipulated into misusing their tools. Write-ups will appear on this site as the work produces results.
AI agents at Tatil Sepeti
Built AI agents with Claude Code at Tatil Sepeti: a RAG-based knowledge assistant that answers from internal documentation and cites its sources, rule-based monitoring whose results are interpreted by an LLM, and scheduled automations. Also set up an AI-assisted development process in which every change passes analysis, development and independent testing steps.
MSc in Computer Engineering (Cybersecurity)
İstanbul Commerce University, completed while leading the team.

First product, sold on CD
While studying business, I taught myself Flash MX and built an animated yearbook on my own, then sold it on CD to four classes at my university. Alongside it I made animations for quiz competitions and multimedia CDs. Projects like these are how I moved from business into software.
