I'm Ronny Silva (ph03nix), a software developer with 4+ years of experience. I take on remote work all over the world and stay available around the clock, so distance and time zones are never a blocker.
4+ years
Professional experience
More than four years shipping real software — from small business sites to full SaaS platforms and production APIs.
Worldwide
Remote by default
I work with clients and teams across the globe, adapting to their time zone, tools and workflow as if I were sitting next to them.
24/7
Always reachable
Round-the-clock availability. When something matters — a launch, an incident, a deadline — I respond and stay on it.
I design and build complete digital products, working across the entire stack instead of just one layer of it.
My work spans frontend interfaces, backend services, APIs, databases, mobile apps and the infrastructure that runs them. That full-stack perspective means I can reason about a product end to end — how the data is modeled, how the system behaves under load, and how it feels to use.

Iterative development with regular feedback.
Deployment, testing, optimization and handoff.

I use modern tools and frameworks to create maintainable, long-lived software.
You work directly with the developer building your product — no layers in between.
