About

As a seasoned full-stack developer, I have over three years of experience working with both front-end and back-end technologies. On the front-end, I specialize in JavaScript and React, with skills in server-side rendering, static site generation, and responsive web design. I’ve worked with frameworks such as Next.js, Redux, and TailwindCSS, creating seamless and efficient web applications. My expertise also extends to back-end development, where I build REST APIs using Node.js, Express, and Nest.js, and manage databases like MongoDB and PostgreSQL. In my roles, I take pride in delivering practical and business-driven web solutions, focusing on reliability, commitment, and strong business process understanding. My full-stack experience includes everything from creating APIs and integrating external services like AWS and Firebase to designing dynamic user interfaces with tools like Styled Components and GSAP. I’ve also led teams in managing full-stack app deployments, applying best practices in testing, design patterns, and cloud solutions to deliver high-quality results.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
