My personal site, with more under the hood than a static page. Google OAuth login, an admin panel with live visitor analytics, and an LLM chat that routes to my own Claude subscription over a local bridge instead of paying per token, so each message costs me nothing. Built on Workers, D1, R2, Pages, and a Cloudflare Tunnel.

Two agent systems I built and keep running. papers-net drafts research papers through a master/director/worker/critic pipeline and checks its own output across four model families to catch hallucinations. karpathy is a personal autonomous agent: it sets its own goals, spins off work packets, and verifies what it finds. Both run on 5-minute systemd timers with SQLite state, on my own machine, no one watching them.

A free lecture-notes platform for my university, built with a few friends. 2,500+ materials indexed so far, plus a pipeline that auto-generates clean study notes from raw uploads. No ads, no paywall, and people actually use it. Live at thelecturenotes.com.

A Freqtrade bot, a Flask/Plotly dashboard, and conformal-bandit, a position sizer that uses conformal prediction to size bets by how confident the model actually is. I wrote it up as a methodology paper, including the honest result that the naive backtest oversold the edge, which is the part most writeups leave out.

A move-out / second-hand marketplace for Turkish university students. Student-email verification, a separate subdomain per campus, automated NSFW image pre-screening, bot protection, and the KVKK data-protection plumbing a real user platform actually needs — the unglamorous parts most side projects skip.

A spoken-Q&A tutor I built to practice technical interviews. It asks questions out loud with a local TTS voice, transcribes my answer with local Whisper, and a Claude-CLI grader scores the spoken answer on five axes, then reschedules weak concepts with spaced repetition (FSRS). FastAPI backend, runs fully on my own machine at $0 per session.

Drafts I'm writing by hand and with my own agent tooling: a Pinney–Ermakov paper (sent to a professor), a smooth-classification paper, a Bohlin-cascade closed form, and a boundary-substrate cosmology paper. This is where the agent systems above and the physics feed each other.
