I am a dedicated Full Stack Developer specializing in TypeScript, Node.js, and React/Next.js. My primary focus is on architectural quality, leveraging a DevOps Mindset to ensure that applications are scalable, maintainable, and deployed efficiently.

I specialize in the following high-impact areas:

• Backend & Architecture: Implementing Clean Architecture and Domain-Driven Design (DDD) using modern frameworks like NestJS and Fastify.
• DevOps & Automation: Experienced with Docker, CI/CD, and applying Infrastructure as Code concepts (Terraform) to streamline deployment.
• Testing: Committed to high-coverage testing using Jest, Vitest, and Playwright for robust, bug-free releases.
