Ioannis Tsirovasilis
Tech consultant and software engineer
I help teams design, build, and ship web products that hold up in production — from architecture and APIs to the interfaces people actually use.
A senior engineer who still likes the details
I am a software engineer and tech consultant based in Greece, working in English and Greek. I have led backend and product work at companies like Repath, and I now help founders and teams turn ideas into reliable software — websites, APIs, and the systems around them. I care about clear communication, honest trade-offs, and code that other people can live with after I leave.
How I can help
A focused set of offers, not a catalogue of every technology on the market.
Product engineering
Custom websites and web apps, built around your brand and the way your users actually work.
Architecture and APIs
System design, integrations, and backends that stay understandable as the product grows.
Commerce and CMS
Online stores and content platforms — including Payload and similar tools — so your team can run the site without waiting on a developer for every change.
Technical advisory
Stack choices, delivery plans, and hands-on reviews when you need a senior engineer in the room, not another slide deck.
How we work
A short loop. No mystery methodology.
01
Discover
We clarify the problem, the constraints, and what “done” looks like. You get a practical plan, not a 40-page proposal.
02
Build
I design and implement in small, reviewable steps. You see progress early and can change direction before it gets expensive.
03
Ship
We go live with monitoring, handoff notes, and a system your team can keep. I stay available for the first stretch after launch.
Selected work
A few public demos. Real client work is usually quieter — and covered by NDA.
La Bella Italia
A restaurant site with menus, atmosphere, and a booking-ready presence.
