Latest work
Backend reliability
Making Notification Delivery Recoverable
- NestJS
- Prisma
- BullMQ
- PostgreSQL
A notification could be discovered, saved, and still vanish before delivery. I rebuilt that handoff so interrupted work survives crashes, with the leftover duplicate risk spelled out.
Company website
Narusec, Explained in Motion
- Next.js
- React
- TypeScript
- Tailwind
A bilingual company site for a Greek software and AI team. The pitch stays quiet; a cursor-lit hero and an animated voice pipeline do the heavier work.
Voice interfaces
Nine States for One Phone Call
- TypeScript
- Bun
- XState
- Soniox
A Greek voice agent that books appointments over the phone. The hard part isn't speaking, it's knowing when to stop: nine states, one of them just for being interrupted.
About me
I started in 2021 with realtime trading interfaces, then moved through production card systems into multi-tenant SaaS. Since then I’ve worked across frontend performance, APIs, payments, queues, databases, and cloud infrastructure, where product decisions stop being abstract and start becoming machinery.
