Backend & APIs
Laravel apps, REST integrations, OAuth flows, scheduled jobs. The kind of code you come back to six months later and still understand.
Full‑stack developer · Czech Republic
Mostly backend. Also whatever breaks on the server.
I've built and maintained web apps — Laravel services, PHP shops, payment integrations, admin panels, and the occasional Svelte UI when frontend work lands on my desk.

What I do
The usual layers, not always in that order.
Frontend & UI
Responsive layouts, SCSS, JavaScript, e‑shop components, admin screens. I fix slow pages and broken forms more often than I design from scratch.
Databases
MySQL, MariaDB, SQLite, Firebird, SQL Server. Migrations, reporting queries, recursive CTEs, and cleaning up data that should never have looked like that.
Servers
Debian, Apache/Nginx, vhosts, SSL, cron. A lot of SSH, reading logs, and figuring out why something worked yesterday.
Recent work
Things I've actually spent time on.
Teya POSlink payment service
Laravel app for terminal payments — requests, status polling, refunds, token refresh. Scheduled jobs sync merchant/store/terminal data from Firebird.
- Encrypted token storage and refresh rotation
- Overlap-protected scheduled jobs
- Payment state updates from Firebird sync
B2B/B2C production web app
Custom PHP app with nested categories, dynamic forms, file uploads, and CKEditor in admin. Lots of recursive SQL and AJAX forms.
- Recursive category/product queries
- File uploads over AJAX
- UI performance and image handling
2D editor interface
Svelte/Rollup editor — undo/redo stacks, pricing logic, material picker, canvas-style interactions. Also build tooling and state bugs.
- State snapshots with stack deduplication
- Drag-aware history
- Rollup config troubleshooting
Server and domain setup
Linux hosting for several domains — vhosts, Certbot, cron, routing between Apache and Nginx. Mostly SSH and log files.
- Apache/Nginx diagnostics
- Certbot and vhost config
- Production triage from the CLI

About
Boring code beats clever code.
Day to day that's backend logic, API integrations, database work, responsive frontends when needed, and server config when something stops responding. Based in the Czech Republic.
