I craft accessible, high-performance web applications that solve real business problems.
Specializing in React, TypeScript, and Next.js, I've delivered scalable solutions for fintech, e-commerce, and enterprise clients—turning complex requirements into elegant, user-friendly experiences.
I'm a Software Engineer with a Bachelor's in Software Engineeringfrom the Universidad Dominicana O&M, and over 9 years of experience building fast, accessible, and scalable web applications.
I specialize in React, TypeScript, Next.js, Node.js, spring Boot, PostgresSQL, and MongoDB. I've built user-friendly solutions across fintech, e-commerce, and enterprise SaaS platforms, using tools like Prisma and GraphQL, to solve complex problems with clean, maintainable code.
I care deeply about performance, accessibility, and attention to detail. I'm committed to best practices and continuous growth. Outside of work, I stay active and enjoy quality time with family.
