Rogerio J.

Vetted Developer in Brazil (UTC-3)

I like working on the parts of software that users don’t always see but definitely feel: the platform, the architecture, the guardrails. My background spans scalable web systems, security-minded engineering, and frontend work in TypeScript, React, Node, and Python. I’ve built features and infrastructure across complex products, from consent flows and privacy systems to high-traffic commerce and media platforms. Along the way, I’ve helped improve onboarding, tighten development standards, and create interfaces that are easier to use without sacrificing speed or reliability.

Wilson K.

Vetted Developer in Brazil (UTC-3)

I'm a mobile software engineer with over 7 years of experience. Most of my projects were organized with scrum methodology, which I find very useful. In the past 7 years, I've learned that delivering features very fast, or having 100% unit test coverage are not the most important things. The most important thing is to solve the problems your team and your client has. In some ways, delivering features and unit testing them will solve these issues, but it's important to know how I'm making things better and being positively impactful. I'm a strong believer that a united team is essential for success, that helping each other will always be rewarding.
