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 11 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.
I developed a full-stack SaaS application that enables developers to create, manage, and share mock REST APIs without writing backend code. The platform includes advanced features like OpenAPI import, JWT authentication, admin analytics, and rate limiting.
