About
I'm Edu Wass, a senior full-stack engineer with a Computer Science background and 10+ years of experience building production web platforms and backend-heavy systems.
I specialise in system design, API architecture, real-time features, and performance optimisation. I'm comfortable owning features end-to-end — from scoping with stakeholders through to shipping and rollout — and I make pragmatic decisions when trading off speed and completeness.
Comfortable across TypeScript and PHP, from Node.js and custom APIs to database modelling and cloud infrastructure. I've worked across startup-to-scale transitions, managing technical debt while keeping systems reliable.
Outside of work you'll find me enjoying music production, sports and fitness, or gaming.
