About Me
As a Senior Software Engineer with over nine years of experience, I specialize in building scalable, frontend focused full-stack web applications using JavaScript and TypeScript. My expertise is centered around the React and Node.js ecosystems, where I use frameworks like Next.js and Nest.js to create robust, user-first solutions with a focus on clean, performant code. Throughout my career, I've led development on enterprise SaaS platforms, e-commerce systems, and mission-critical government applications. I have a strong background in designing both microservice and microfrontend architectures, which has been key to improving team velocity and system scalability. I enjoy collaborating closely with product teams, mentoring fellow engineers, and championing modern development practices like CI/CD and test-driven development.
