Senior Ruby on Rails developer at Yasno, building billing for 1M+ paid invoices a year and automated payouts to therapists.

At Yasno, I built and run billing for an online therapy platform, processing 1M+ paid invoices a year. I handle failed-payment retries, refunds and multi-currency invoicing, and built automated therapist payouts and fiscal compliance workflows.

I also built the backend for a new child-therapy product line and made CI 1.5× faster by optimizing the test suite without reducing coverage. In my own projects, I build LLM-powered products end to end with TypeScript and Node.js.
