About me

view cv
  • I'm someone who builds while figuring things out. I don't wait to understand everything before starting. I learn by creating, iterating, and pushing ideas into reality.
  • Most of my work sits at the intersection of AI and real-world systems. Whether it's building agentic workflows, experimenting with LLMs, or designing end-to-end applications, I'm driven by the process of turning abstract ideas into something tangible and useful. Recently, this has ranged from developing AI agents and RAG-based platforms to working on ML pipelines and real-world anomaly detection systems.
  • At the core, I'm deeply curious—not just about how systems work, but about how technology influences people: how they think, decide, and evolve. That curiosity pushes me beyond just writing code into understanding the "why" behind what I build.
  • For me, growth isn't just about stacking skills or achievements. It's about becoming more aware, more disciplined, and more aligned with the work I choose to do. And that's something I'm continuously working on—through every project I build and every problem I try to solve.
