Summary
👤
SeniorThomas Wieser is a senior backend engineer with over two decades of practical experience and 11 years in focused roles delivering resilient, high-performance backend systems. He designs and rescues complex backend architectures end-to-end—from deep database optimizations and CI/CD recovery to pragmatic QA and frontend bottleneck diagnosis—having cut multi-hour data imports to under a minute in production. Comfortable in high-pressure, stalled, or fast-scaling projects, he blends modern DevOps patterns (Docker, Kubernetes, PostgreSQL) with test-driven pipelines and strategic tech guidance for CTOs. A long-time FOSS advocate, he favors cost-effective, vendor-neutral solutions and embraces AI-assisted development only when it materially improves productivity. His background ranges from hands-on consulting and plugin development to leading quality management at MoneyPark, giving him a rare mix of diagnostics, implementation, and process-building skills. Based in Landquart, Switzerland, he thrives on tackling thorny backend problems where reliability and clean architecture matter most.
