Summary
👤
Senior🎓
Top SchoolChristian Zwergius is a frontend developer with 11+ years of experience crafting performant, accessible web and mobile interfaces for clients ranging from startups to global brands like British Airways, Jaguar Land Rover and Heineken. A perfectionist by nature, he specializes in architecting projects with the right tools—JS/TS, Svelte/React/Vue, modern meta-frameworks and serverless deployments—while obsessing over performance, semantics and cross‑browser accessibility. He helps teams lacking front-end expertise by driving planning, code reviews and best practices, and has a track record of porting legacy apps to modern stacks and creating reusable open‑source wrappers for web crypto. Based in Madrid, he blends hands‑on UI polish and animation with pragmatic engineering principles (SOLID, KISS, YAGNI), and is equally comfortable shipping PWAs, React Native apps or headless CMS-driven sites. An avid problem solver who enjoys tuning the last detail, he pairs client-facing freelance work with ongoing product and consulting engagements.
