About

Engineer and founder building AI systems that know when to stop and validate. Currently co-founding Keel Technologies, where we turn messy maritime documents into structured intelligence using multi-agent pipelines — winning 1st place at the Panathenea AI Hackathon along the way.

Before this, I ran Metagalerie, an art-tech company where I built Artisto, a gallery management SaaS. I studied some mathematics, picked up economics, and eventually retrained in software engineering at Zone01 Athens.

I care about making AI agents reliable enough to actually ship. Most of my recent work is about putting guardrails on LLM autonomy so the output is trustworthy, not just impressive.

Projects

Selected repositories and open-source work.

  1. two-tier-safe-ai-gate

    go sdk2 omnigent inngest docker

    A safe execution harness for AI agents. Separates unconstrained LLM exploration from deterministic validation boundaries so agent actions are verified before anything runs.

  2. keel-multi-agent-pipeline

    1st place python langgraph pydantic fastapi

    Multi-agent pipeline for processing complex maritime paperwork. Uses orchestrator, worker, and validator agents to extract structured data from unstructured documents. Won 1st place at the Panathenea AI Hackathon 2026.

  3. social-network

    go next.js postgresql docker ci/cd

    Full-stack social platform built with Go and Next.js. Designed around modular vertical slice architecture with decoupled adapters for database, messaging (queues & pub/sub), and caching.
