Hi, I'm Demetri — a Senior Solution Engineer in Thessaloniki. I build the technical bridges between complex platforms and the teams who depend on them.
Migrated a 200K-SKU industrial catalog from a 14-year-old legacy quoting system to modern CPQ — without a single day of downtime.
Designed and shipped a tenant-isolated API gateway serving 40+ enterprise customers with per-tenant rate limits, auth, and observability.
Replaced a nightly batch ETL with a streaming pipeline delivering sub-minute customer analytics to a Fortune-500 logistics firm.
Designed a documentation + sandbox portal that took new API customers from signup to first successful call in under 9 minutes.
