About Denys
Denys has been building software for more than 10 years. He started programming in 2013.
He is a team lead who reviews other engineers' code every day.
He has worked on a real-time analytics platform used by 200+ companies.
He has reviewed 20+ apps built with AI tools. In those reviews, the same problems keep coming back: AI bills that climb, pages that slow down, logins that break.
He also saw that founders often struggle to describe a fix to their AI tool. A vague prompt fixes one thing and breaks another. That's why every SELFOIA finding comes with a ready-to-paste fix prompt and a 2-minute check.
He founded SELFOIA so founders who build with AI have someone technical on their side: plain English, fixed prices, no rewrite unless they want one.
What he reviews
Apps built with Lovable, Bolt, Cursor, Replit, v0, Base44 and Claude Code, usually running on Supabase or Firebase, Stripe, OpenAI or Anthropic, and Vercel or Netlify. He checks five zones:
Leaks: keys visible in the browser, open database rules, public files.
Break-ins: users seeing each other's data, unprotected admin pages, weak logins.
Money: Pro without paying, AI features anyone can run up.
Speed: slow queries, heavy pages, apps that stall when real users arrive.
Safety net: backups, alerts, risky packages, code that breaks when you touch it.
