What I do

I cover the full engineering lifecycle — from system design down to deployment pipelines.

01

Architecture & Backend

Designing systems that don't fall over under load. I care about clean APIs, sensible data models, and infra that doesn't surprise you at 3am.

02

AI Workflow Integration

Plugging LLMs and automation into real editorial and operational workflows — not as a gimmick, but when it genuinely cuts time or improves output.

03

Product & Frontend

Fast, accessible interfaces built to keep users. I focus on the details that affect conversion and retention, not just how things look in a mockup.

Selected work

A handful of projects I'm proud of — each one solving a real problem for a real business.

About

A bit about me

I'm a software engineer based in Greece with a computer science background and 3+ years shipping real products. I work best with founders who want someone that thinks about the whole problem — not just the ticket in front of them.

  • ROI before elegance. I think about user value and business impact before I write a line of code.
  • Maintainability matters. Code you can hand off is worth more than code only I can understand.
  • No black boxes. You'll always know the reasoning behind every technical decision I make.
