What I work on.
I've been writing software for over twelve years, mostly PHP. At work it's fintech: loans, credit scoring, systems where a parser that quietly returns a default value ends up as a decision about someone's money.
After hours I run my own things in production: CookieDomain, a cookie consent platform in Laravel, a risk-assessment SaaS, a handful of n8n automations. They live on two small VPSes and a home server, where I also run local models through Ollama. The first lesson there was 12 tokens per second on CPU. Most of what I write here about deploys and agents comes from that setup, including the evening I switched off the old n8n before DNS had actually moved.
I write code with AI agents now. One writes, another plans and reviews, I decide what goes in. When I catch myself saying "well, it depends" without saying on what, I go back to the code.
who I am
I am Tomasz Kulesza. I currently work at Miloan sp. z o.o., where I spend most of my time on PHP systems that move money around and try not to lose it.
This place now is my collection of things that survived a collision with production. Heavily PHP-based, because that's what most systems I deal with run on. The rest is the boring stuff at the edges: payment gateways, state machines, idempotency, deploy scripts, file permissions. That's usually where it breaks.
