About William

Front-end & Mobile Developer -> 5+ years of experience

After several years as a salaried developer for an application publisher, I am now working on Malt.
I have contributed to numerous projects (web & mobile) which have allowed me to acquire solid expertise, with a strong sense of optimization and quality.

What I can do:

Web Front-end(React / TypeScript / Tailwind) -> pixel-perfect integration, performance, animations, SPA

Mobile / Tablet(React Native / Flutter) -> cross-platform apps, offline-first, modern UI


Back-end(Node / Next / REST APIs) -> REST APIs, monolithic applications, DevOps, CI/CD


CMS(WordPress / Headless) -> custom integrations, performance, technical SEO


My strength:

Autonomous, organized, and capable of quickly acquiring new skills for a business need.
I like to deliver clean, robust, and documented code.
