I'm Enes. I build products and the companies around them.

How I got here
Software is the fastest way I know to turn an idea into something people can use. I study Computer Engineering at Gazi University, and most of what I know about building came from shipping my own products.
In 2024 I started building ventures. Unicore Social began on campus, as a social platform for university life. Cally put AI voice agents on business phone lines. Memento Mail, first called Needle, was an AI email workspace for the work that hides in an inbox. Yok.la made personnel and field operations visible. Different markets, the same habit: find a workflow that hurts, then build the thing that fixes it.
Those projects are no longer in active development. They left me with something more useful than a portfolio: I have written the backend and the pitch, sat in onboarding calls and fixed production bugs at night. Now that experience goes into one company.
Derbent
In 2026 I co-founded Derbent with Ahmet Utku Çakan. We are building a security and context layer so people and companies can use advanced AI models without opening their sensitive data to them.
It is still in development. In October 2026 we took second place at Webrazzi Arena.
Engineering
I'm a technical founder. I design system architecture, write backend and frontend code, wire LLMs and agents into products, and deploy and run what I ship. I have also built software for clients, such as KOAH, a healthcare workflow system, which I keep separate from my own ventures.
How I work
- Start from a real problem, not from a technology.
- Ship a working version early, then harden it with real users.
- Own the whole loop: architecture, code, interface, pitch, first users.
- Keep claims concrete. If it isn't built yet, say so.
