About me
I work best in environments where product quality, technical clarity, and execution all matter . As a senior software engineer with 5+ years of experience, I deliver scalable web and mobile applications for global enterprises across fintech, e-commerce, and entertainment. My work spans the full lifecycle, from discovery and architecture to implementation and release, including legacy migrations, performance optimization, and AI/LLM-driven automation. From Colombia, I collaborate with global teams to turn complex requirements into reliable releases through strong ownership, thoughtful architecture, and clear communication.
Technical expertise
Product-minded frontend systems with full-stack depth
My core strength is building refined interfaces and scalable frontend systems with React, Next.js, and TypeScript, then extending that work into NestJS, Java, cloud services, and mobile delivery when the product calls for it. I also bring hands-on experience with performance and load testing, legacy migrations, and AI/LLM-driven automation.
Global collaboration
Trusted by distributed teams that value ownership
I've worked with international teams across the US and Europe, partnering with companies such as Electronic Arts, Sephora, EPAM, and Globant. Teams rely on me for steady execution, end-to-end ownership, strong cross-functional communication, and the ability to balance delivery speed with maintainability.
I care about more than shipping code. I enjoy helping teams make better technical and product decisions, mentoring other developers, and creating systems that remain maintainable as they scale. My current focus is on combining strong product execution with scalable architecture, AI/LLM-driven automation, and performance optimization, delivering reliable, high-quality solutions for enterprise teams.
