Oscar Cocom
Hello, I'm Oscar Cocom — a Senior Software Engineer with over 9 years of experience specializing in Fintech, Banking, and E-commerce. Expert in Fullstack development and scalable architectures, I focus on building high-performance, secure digital experiences.
About
Senior Software Engineer with a proven track record of leading high-concurrency platform development from conception to deployment. I specialize in microfrontends and microservices architectures, ensuring security and code quality through best practices like TDD and SonarCloud.
Over the past 9 years, I've orchestrated the modernization of mobile banking systems, integrated global tourism APIs, and built social media platforms with real-time synchronization. My expertise spans the JavaScript/TypeScript ecosystem with React.js, Angular, Node.js, and complex state management.
Focused on optimizing operational efficiency and user experience, I bridges the gap between complex backend architectures and high-performance frontend interfaces. From AI implementation with RAG architectures to secure authentication with JWT and OAuth2, I build scalable solutions for the modern web.
