I'm Iraklis Gkougkoudis, a backend and mobile developer in Athens, Greece, and founder of the software studio ZYXEN. I currently work as lead backend developer on an enterprise Umbraco/.NET platform.
Through ZYXEN I take on part-time, project-based work: about 10-20 hours a week, fully remote, in a European time zone. Typical work:
- Umbraco builds, upgrades, support and custom features
- C# / ASP.NET Core REST APIs and third-party integrations
- Flutter / Dart mobile apps, including iOS builds in Xcode
- Azure, Docker, Kubernetes and GitHub Actions CI/CD
- OpenAI integrations in .NET or Flutter apps
Before that, at Redirect S.A. (2024-2025), I worked on projects for IPS Industrial Plastic Solutions, Victoria De Borbon, paxisarkiakaipaidi.gov.gr and Creta Maris.
All work is invoiced B2B through ZYXEN (zyxen.gr). CV on request.
