I build
data-driven tools & backend systems.
SQL, backend development and AI-assisted automation. Building production systems with real-world data. Main focus: dragon-island.com — a production CMS running on live MSSQL data with ~1,000 registered users and 100+ Stripe transactions. I also build data tools, backend systems and game-server technology.
Selected projects
7 projects spanning data tools, production systems, backend and game-server engineering.
About
I build data-driven tools, backend systems and automation using an AI-assisted workflow. My strengths are understanding existing systems, breaking down complex problems, working with databases, and turning ideas into working production software. I use AI extensively to accelerate development, while keeping architecture, validation and technical decisions under my control.
I use AI to move faster, not to replace understanding.
Most projects started as 'can this be done?' and ended up live: a production CMS on real MSSQL data, a browser-based data profiling / EDA tool, and a monorepo CV builder on PostgreSQL. Remote-friendly, EU timezones preferred. English is strong for written work, PRs and docs; actively levelling up the speaking side.
