Fullstack Developer

Male, 28

5+ years experience

live in Buenos Aires, Argentina

I am a full stack developer with extensive experience in React, Node.js, TypeScript, and JavaScript. With a deep understanding of Redux, React Query, Next.js, and React Native, I have a proven track record of delivering high-quality, scalable, and maintainable applications. My expertise in Docker, Jenkins, and other ops technologies has enabled me to design and implement seamless deployment pipelines and ensure the smooth running of applications in production.

I have also worked extensively in networking technologies such as Nginx, SSL, REST API, Websockets, P2P, and Load Balancing, delivering fast and responsive applications that meet user expectations. My experience with PostgreSQL, MongoDB, and Prisma databases has given me the ability to design and implement efficient and scalable data models.
