I am a Fullstack Developer with a focus on Backend, experienced in the e-commerce, finance, B2B, and B2C sectors. I develop robust systems using Node.js and TypeScript, working with JavaScript, Python, and NestJS on the backend, and complementing projects with Vue.js/Nuxt.js on the frontend. I have theoretical knowledge in blockchain and Web3, with practical experience in frontend Web3 implementations using Web3.js and Ethers. I work with databases such as PostgreSQL, MySQL, and SQL Server, and manage AWS services (Lambda, EC2, S3, DynamoDB, VPC, API Gateway). Additionally, I use monitoring tools like Grafana, Kibana, and NewRelic, along with development and testing tools (TypeORM, Supabase, Jest, JMeter, Postman) to ensure project quality and scalability. I follow agile methodologies (Scrum, Kanban, Shape Up) for efficient project delivery.
