## What I'm looking for

```text
I'm looking for remote, part-time contractor work, with the scope agreed for each engagement. I'm available to start immediately.
```

## About

```text
At RoutineBridge, I build customer portals, bank and REST API integrations, data pipelines, and operational tools for clients including Gaya, Hakom, and Aluprint. One customer portal is in live use, with PIN login, invoices, contracts, service requests, and online payments.

I also integrated statements and payment orders from three Slovak banks into SQL Server, with OAuth2 token refresh, camt.053 parsing, and duplicate suppression. Other work includes cash-register and courier APIs, production-prep tooling, Raspberry Pi kiosks, and operations automation.

In 2026, I created Tender vopred, an own product that uses Slovak public contract data to show suppliers contracts expiring in 1–12 months. I also developed workflows using Codex CLI and Claude Code, with independent reviews and tests; one project produced 56 Python files and 1,009 tests.

I use Python, PHP, SQL, and web technologies, as well as AI coding agents with independent checks on their output. I'm a Bachelor's student at Brno University of Technology and am available for remote, part-time contractor work, with scope by agreement.
