I build and run AI agent systems and full-stack products, solo.

Most of what I make is deployed and running in production — and a lot of it keeps running without me watching it. I taught myself the stack and I ship, fast.
About
I study physics at Bilkent and taught myself everything on the software side — mostly by building things at hours I should have been asleep.
What I keep coming back to is systems that run themselves: agents that set their own goals, pipelines of models that check each other's work, infrastructure that costs almost nothing to keep alive. I work solo and fast — I'd rather have a rough thing running tonight than a perfect plan for next week.
I also care about the parts nobody screenshots — auth, moderation, data protection, not falling over at 3am. That's the difference between a demo and something people actually use.
What I work with
Selected work
Things I've built and shipped
sirschrodinger.com
full-stack · liveMy personal site, built like a small OS: Google OAuth, an admin panel with live analytics, and an LLM chat bridged to my own model. All on Cloudflare Workers, D1, R2, Pages and a Tunnel.
papers-net & karpathy
multi-agent · runningTwo agent systems I built and keep running. papers-net drafts research papers and verifies its own work across four model families to catch hallucinations; karpathy is an autonomous agent that sets its own goals and checks what it finds. SQLite state, systemd timers.
defter / thelecturenotes.com
platform · liveA free lecture-notes platform for my university — 2,500+ materials indexed, plus a pipeline that auto-generates clean notes. No ads, no paywall, real users. Built on Cloudflare.
Trading stack & conformal-bandit
quant · paperA Freqtrade bot, a Flask/Plotly dashboard, and a conformal-prediction position sizer. I score signals with permutation/walk-forward tests and drop what doesn't survive — and wrote it up as a paper with an honest negative result.
yurttanayriliyorum.com
marketplace · liveA move-out marketplace for Turkish university students, shipped solo: student-email verification, a subdomain per campus, automatic NSFW image pre-screening, and KVKK data-protection plumbing — the unglamorous parts most side projects skip.
Berin
AI · voice · localA voice mock-interview tutor I built to drill technical interviews: it speaks questions, transcribes my spoken answer with local Whisper, and an LLM grades it on five axes, then reschedules weak spots with spaced repetition. FastAPI, runs on my own machine.
