Senior🎓
Top SchoolJonathan Fenske is a senior software engineer with over 17 years of professional experience and a proven track record building scalable, cloud-native services and developer-facing tools. He’s delivered performant Go microservices on GCP (Bigtable, Elasticsearch, Redis) and full-stack systems using Java/Kotlin Spring Boot, Node/TypeScript, NestJS, and Flutter for mobile frontends. Comfortable across AWS and GCP, he’s built internal analytics and troubleshooting tooling, shipping integrations with Mirth Connect and SQL-driven reporting pipelines. As a founding engineer at a sports-team app he handled both Flutter UI and backend infrastructure, and his open-source front-end work includes usability and security-focused contributions to the yopass secret-sharing project. Colocated in Cadiz, Kentucky, Jonathan combines deep backend performance instincts with frequent front-end and testing improvements, making him effective in small, remote teams that need hands-on contributors across the stack. He’s particularly adept at turning complex data flows into practical diagnostic tools that accelerate support and reliability.
