Some of the tools used to develop and deliver are: Jest for unit testing, Git flow, Docker, CircleCI, ArgoCD, SonarQube and Code Climate, DataDog, and the ELK stack.

Developed a microservices infrastructure for new projects and migrated old ones following a DDD approach when possible. Managed a group of developers to follow best practices and meet deadlines using agile methods. Utilized Node.js/TypeScript, Docker with AWS ECS/Fargate, Redis with pub/sub, AWS SQS, RabbitMQ, GraphQL, and Rest APIs against MySQL (Sequelize) and MongoDB (Mongoose). Tested with Jest and worked with Angular 9.

Developed a new microservices backend using Node.js with TypeScript and alternating between GraphQL and Rest endpoints. Also collaborated with the frontend development using React (Redux, Mobx, rebass, theme-ui, Emotion, SWR). Utilized AWS (Lambda, S3, ECS) and Docker for microservices and the ELK stack for monitoring, with MongoDB as the database.

Worked as a frontend developer using React, Redux (+thunk), Styled Components, Axios, Lodash, Normalizr, Material-UI, AtlasKit, PWA, and more.

Created internal applications with Angular 5 and Node.js, built Rest APIs with Node.js (Express) and Swagger, managed SQL databases, monitored and debugged APIs, handled Windows APP/Web Servers, performed rollouts and deployments, supported CDNs (Limelight, Cloudflare, CDNetworks), and used tools such as Confluence, Jira, and Swagger.

Developed and maintained applications using Angular2/4, Bootstrap, Node.js, and MySQL. Also developed scripts in Python and Bash.
