Abel A.

I build full-stack web applications with React, TypeScript, Java/Spring Boot and Supabase — from MVPs that launch fast to enterprise systems that handle real users and real data. Top Rated, 100% Job Success, 5 years of production experience. I'm Abel, a full-stack engineer. I pick the right stack for your project: → Need to launch fast? React + Supabase (auth, database, storage, real-time) + Stripe payments — a working MVP in weeks, not months. → Need enterprise-grade? React + Java/Spring Boot microservices, PostgreSQL, Kafka and Keycloak security — built to scale and stay stable. → Already on Supabase but outgrowing it? I can add a Spring Boot backend for complex business logic while keeping what works.
