Umut Yunus Yeşildal
I build tools people actually use: job search for Germany, stock baskets on Solana, and a sci-fi deck-builder when the weekend allows.
Based in Berlin, finishing a Master's at Humboldt.
Expertise, what I worked on before.
I have worked across mobile, web, data and onchain. These are the things I am best at today.
Product Engineering
End to end: Python crawlers, Postgres, Next.js frontends. I ship the boring parts too, including CI, deployment and the cron jobs nobody wants to own.
AI Agents
Agent skills, MCP servers and n8n workflows. I build tools that run inside Claude Code, Codex and OpenCode instead of yet another chat window.
Solana
Anchor programs, Token-2022, xStocks and wallet flows. Basalt, my basket protocol, won the Road to Colosseum Germany ideathon.
