GreeceWhat I'm looking for
Software engineer and solutions architect with 20+ years designing, building, and operating production systems end to end — from mission-critical, regulated banking infrastructure to modern, multi-provider AI platforms. Deep full-stack range across .NET/C# (Framework through .NET Core 9), PHP, Node.js, and React, with hands-on ownership of cloud infrastructure (AWS, Azure, GCP), security, DevOps, and zero-downtime migrations. Repeatedly delivers large, complex platforms largely solo or leading very small teams, and — since 2025 — orchestrates fleets of AI coding agents to multiply individual output. Combines strong engineering depth with architecture, leadership, and a pragmatic, business-focused mindset.
