About
Ten years in production.
I take products from the first commit through years of production. Hospital IT, clinical software, a workforce platform, now telecom admin. Short chapters are labeled as such.
The craft is still the web: PHP backends, typed frontends, data stores, and the operations that keep a site up. The desk changed. Cursor, Grok Bot, Warp, and TablePlus are how I write, review, and ship in 2026. AI is in the product too: call transcription at ArenimTel, AI-assisted workforce tooling at Login Autonóm.
AI drafts. I still ship. Anything that goes to production is read, understood, and edited to the bar I hold my own work to.
Laracon 2017 and 2018. Hungarian Web Conference 2016. I work in English and Hungarian.

Durations on the long roles. Hinora was a summer internship. EPAM was a Planimeter contract, months not years.

How the desk works
Generated output is reviewed and edited before it ships.
Cursor
The editor. Agents draft across Yii, Angular, and this site. I review the diff before it lands.
Grok Bot
A desktop agent. It researched and shipped this site. Same rule as production: I read it before it goes live.
Warp
The terminal. Commands as blocks, agents on the same surface, deploys without a second window.
TablePlus
Native MySQL and Redis. Production schemas, not a browser tab.
Termius
SSH without a second laptop. Hosts, keys, the machines that are not this one.
Evernote
Notes that survive the job. Specs, snippets, the thread I will need in two years.
Postman
REST without a browser tab. The same APIs the Yii and Angular work talks to.
LastPass
Credentials, not a spreadsheet. Work and personal vaults.
