What I'm looking for

I seek a collaborative, agile team role where I can build end-to-end web applications, grow in architecture and DevOps, and deliver high-quality, user-driven solutions.

I am a Full Stack Developer specializing in responsive frontend interfaces and robust backend APIs using React, Next.js, Node.js and TypeScript.

I have delivered end-to-end projects from design to deployment, incorporating TDD, Clean Architecture, and client feedback to maintain high code quality.

My experience includes building secure RESTful APIs with Express, integrating MySQL databases, deploying cloud solutions on AWS (EC2, S3), and using Docker for containerization.

I work well in agile teams, use Git for collaboration, and prioritize maintainable code, thorough reviews, and iterative improvements driven by user needs.
