It starts in Ukraine
Born in Dnipro in 2004. As a kid I could disappear into the computer for whole days – and I never really came back out.

Hi, I'm Denys – a full-stack developer in Oslo, by way of Ukraine and Slovakia. I build things for the web, fly drones whenever the wind allows, and love the moment an idea turns into a link you can open.
Ukraine to Norway, the long way
Full stack, end to end
IT developer apprentice at Comono AS in Oslo. Most of my days go into drone ground-control software – the app an operator uses to plan, fly and watch a drone. I like owning the whole path, from the database row to the button someone finally taps.

Things I have built and shipped
01 / 03
Boardly
Board games with friends, right in the browser. Make a room, drop the link in the group chat, and everyone is playing in seconds – no download, no sign-up. Built with Next.js and Supabase.

Second Brain
My life on autopilot – almost. Claude Code skills, hooks and scheduled routines run my Obsidian vault from a Raspberry Pi: morning briefings, end-of-day logs, budget imports and weekly retros, with a Telegram bot and a dashboard on top.

SEO Analyzer
Point it at a website and get a full SEO audit back in one API call. FastAPI under the hood, a Next.js product on top with accounts, API keys and usage quotas.

Drones
Certified pilot. If the wind is calm, the drone is already in my bag.
Gym
Every other day, push, pull, legs. The best debugger I know – answers often show up between sets.
Water and snow
PADI Open Water diver in summer, on a snowboard the day the slopes open.
Padel and ping pong
Anything with a racket and someone willing to lose to me. It does not always go to plan.
Red Cross
Volunteer. Norway gave me a home – this is my way of giving something back.
Dota 2 and Rust
Evenings with friends, headsets on. Great practice in teamwork – and in losing gracefully.
Let's build something
Got an idea, a side project, or just want to talk code and drones? Say hi – coffee in Oslo or a call online, both work.
