Pablo Rosa

I've delivered and evolved mission-critical applications for a major U.S. payment processor at Ambush, working across React, Next.js, and business-critical legacy systems. I own frontend features from technical analysis through implementation and validation, balancing performance, reliability, usability, and code quality.

At Tarmac.IO, I worked with distributed international teams across sports betting, education, healthcare commerce, financial management, and administrative products. I rebuilt the ROAR assessments platform from scratch, defined its frontend architecture, and created browser audio solutions for React educational games that more than doubled the original performance.

I've also built reusable design-system components with React, TypeScript, and Storybook at Tech6 Group, while leading frontend refactoring and external-team integration work. Across Outplan Tecnologia and Todobit, I've maintained long-lived PHP systems, built web crawlers and mobile products, resolved production issues, and supported applications used by more than 1,000 doctors.

I enjoy clean code, frontend architecture, legacy modernization, and AI-assisted development that helps teams deliver faster without compromising quality. My work spans React, TypeScript, Next.js, Node.js, GraphQL, Angular.js, and serverless applications.
