Ferenc Csiba

Maintenance Team Lead · Billingo

A software developer for ten years, today I make sure nothing falls through the cracks at a SaaS invoicing company — and that engineering works on what actually hurts customers.

I started as a PHP backend developer on Symfony and Laravel, and worked on an online auction platform, an ERP system and even the game-control software of escape rooms.

I joined Billingo in 2022 as a developer; today I lead the maintenance and tech support team: triage, debugging, process design and AI-driven automation, plus data analysis and reporting.

I like systems — code or teams — to be transparent and predictable. Father of several kids, living near Budapest.

  • AI-driven ticket handling: automatic triage, and an agent connecting the customer-service platform with YouTrack (in progress).
  • Company-wide YouTrack workflows: process rules and automatic time tracking.
  • Data analysis and management reporting.
  • AI tools in daily work: Claude Code, Gemini.

Bug tickets that don't get lost

Bug tickets used to be handled ad hoc. We built a prioritised Kanban workflow in close collaboration with customer support and the dev teams. Every ticket now has an owner.

SolvedSeveral weeks → consistently under 15 days (2025) → goal: under 10 (2026)

Rewriting the Vatera API

Together with a colleague I rewrote the complete REST API of Vatera, Hungary's largest online auction site, from scratch in Symfony 2 to power the new mobile app.

SolvedA complete API, two developers, the backbone of the mobile app

Escape room control system

I built the admin system and the game-master control interface for escape rooms, and configured the game-master machines. It became a hobby too.

SolvedFrom job to hobby: ≈50 rooms played
