Wilhelm Werwein

Technical Lead & Senior JavaScript Engineer. I think in systems, ship in details.

// 01  about

Software that lasts — from front-end to system.

As an application developer and technical lead for the JavaScript domain, I'm the technical authority around JavaScript and TypeScript: I'm consulted on technical decisions, set the direction, and establish standards. I'm at home across the entire web stack — from considered front-ends with Vue to performant back-ends; close to the system with Rust and Go, with a confident command of databases. Professionally I build GEO-IT software and bring solid geoinformatics experience. Complex problems are what I enjoy — for every one I find a clean, maintainable solution. From concept through architecture to the last pixel.
