Description

Freelance web, mobile, and PWA developer – Angular · Ionic · Capacitor · Firebase

I design, refactor, and modernize web, mobile, and PWA applications for VSEs, SMEs, startups, businesses, and associations: business tools, extranets, client areas, mobile applications, installable PWAs, offline capabilities, push notifications, Firebase, UX, accessibility, performance, and deployment to stores.

My approach: start with the real need before choosing the technical solution. The goal is to deliver a useful, reliable, maintainable, and user-friendly application, without unnecessary complexity.

• Audit and refactoring of existing projects

• Stabilization of slow, fragile, or hard-to-maintain code

• Deep links, universal links, mobile permissions

• Firebase Auth, Firestore, FCM

I also handle specific needs: Stencil.js, web components, Three.js, complex business logic, Capacitor native bridges, or advanced optimization.
