Founder of TZEKOS[dot]EU — a small studio in Thessaloniki, Greece, building data and API products.
- Job Opportunities API — a ledger of more than 2 million live job listings taken straight from employer ATS platforms, company career pages and public employment agencies. Every field is labelled published or inferred, and every row says when it was last verified. Free tier, REST API, OpenAPI spec.
- REST docs and pricing: jobopportunitiesapi.org
- Pay-per-call on API.market
- Pay-per-result on Apify:
job-opportunities-api— source in JOA-Apify
- Erioun and Kaeros — career and job-search products built on the same data pipeline.
Python, Go and JavaScript — with PostgreSQL as the answer to most questions. I use AI coding agents (Claude Code and Mistral Vibe) daily, and I like data products that publish their own coverage gaps instead of hiding them.
