What I'm looking for

I am looking for a Full Stack role where I can lead technical decisions, mentor developers, work in Agile teams, and build scalable, high-performance web applications.

I am a Full Stack Developer with professional experience since 2018 building responsive, high-performance web applications using React, Next.js, Node.js and NestJS. I focus on delivering scalable, maintainable solutions by applying modern JavaScript/TypeScript and ES6 best practices.

Throughout my career I have designed and implemented backend routes with Prisma/TypeORM and integrated PostgreSQL/MySQL, while improving performance via database optimizations and server-side rendering (SSR). I regularly contribute to high-quality codebases through unit testing with Jest, React Testing Library and Vitest.

I collaborate effectively in Agile environments (Scrum/Kanban), mentor junior developers, and work closely with designers using Figma, Tailwind CSS and Chakra UI to improve UI/UX. I have led architecture and delivery as a principal developer on multiple projects.

I bring strong problem-solving, teamwork and communication skills, and I am committed to writing clean, testable code that scales. I seek roles where I can continue mentoring, drive technical decisions, and build performant user-centered applications.
