What I'm looking for

I seek a collaborative environment that values innovation, growth, and technical excellence.

I am a Fullstack Software Engineer with over 7 years of experience, specializing in front-end development using React and TypeScript. My journey has taken me through various international e-commerce platforms, where I have honed my skills in building responsive, accessible, and high-performance applications. I am passionate about creating maintainable solutions and have a strong focus on testing and code quality.

Throughout my career, I have developed a personal SaaS application to deepen my expertise in back-end technologies such as .NET and PostgreSQL. I thrive in Agile environments, collaborating closely with product teams, designers, and developers to deliver scalable applications. My commitment to best practices, including TDD and CI/CD workflows, ensures that I consistently produce high-quality code.
