About

2017 — Origin

At 17, the question wasn't what do I want to build — it was why does this data look like that? That question didn't leave.

It became 2.5 years at Ozon Tech — one of Russia's largest fintech platforms — building production pipelines and dashboards that CX leadership used every morning. The kind of systems where something breaks at 3am and it actually matters. SQL queries at scale. Python tooling. Airflow DAGs optimised until automation delivered 40% faster.

Not prototype work. Not demo data. Production.

2025 — Present

Now at Georgian College in Ontario — studying full-stack development while continuing to ship projects that actually deploy.

The approach is end-to-end by default: backend data pipeline → REST API → web dashboards → mobile and web interfaces. Airflow orchestrating jobs. SQL and Python handling the heavy lifting underneath. Every piece connected. Every service running in production.

Nothing is simulated here. The bar for "done" is deployed.

Your data.
Their platform.
We changed that.
Languages — Global

Four languages and counting. Russian is native. English is certified — CELPIP 10/12 average. French is real — TCF Canada C2 listening, C1 across the board. Belorussian is in progress.

This isn't a resume section. It's closer to a worldview. Every language is a different way people organise reality — different assumptions baked into the grammar, different things that go unsaid. That gap between languages is where the most interesting things live.

The plan: travel slowly, stay long enough for a place to feel ordinary, then move again.

Signal

Concrete Boys. JPEGMAFIA. Lil Yachty.

What these artists share isn't a sound — it's a posture. They built the infrastructure for their own creative logic, ignored the approval process, and made the thing anyway. The output is always a little strange. The craft behind it is always precise.

That's the creative philosophy that actually makes sense to me: unconventional inputs, rigorous execution, no waiting for someone to hand you the tools.

Hackathon · Georgian College × Honda Canada
AutoHack 2025
April 2025 · Barrie, Ontario

A real engineering challenge put on by Georgian College and Honda Canada. We collected sensor data with C++, spun up PostgreSQL in Docker, trained a predictive maintenance model with scikit-learn, and wired it all up to a web dashboard. Pitched to industry judges and came in 2nd.
