What I'm looking for

I'm looking to work where help is most needed, contributing across stacks and teams while building reliable cloud services. I'm especially interested in learning through new tools and workflows, including local LLM integrations.

At TUI, I build and operate cloud-native backend services that support flight sales, pricing, and company-wide technical enablement. I currently work on a critical flight prices cache handling 23M requests per day, helping keep products sellable and available.

I've migrated six API proxies from Apigee Edge to Apigee X without production disruption, investigated race conditions in price-cache updates, and integrated airline systems for booking fares and services. I also guide partners in using domain APIs and common integration patterns.

In TUI's Technical Enabler Team, I created shared NuGet libraries, custom Kiro skills and agents, and practical guidance that helps other teams deploy and maintain their products. I enjoy working where help is most needed, including stabilizing and documenting orphaned repositories before handoff.

Across 17+ years, I've worked from PHP and Drupal platforms to event-driven C#/.NET services on AWS. Outside work, I'm exploring local LLM integrations with Ollama across different workflows.
