I have been working as a developer for 7 years with vast experience in web and cloud development, as a full stack developer.

I have been working as a developer for 7 years with vast experience in web and cloud development, as a full stack developer. I started in 2016 as a Full Stack Developer for a Health Tech Startup where I developed all my career up to Senior & Tech lead until 2023. I have helped and leaded big projects such as a image store/radiology system(PACS) and a Telemedicine application during COVID-19 pandemic, which both we had a great success in the majority of hospitals in Brazil. In 2023 I accepted another opportunity to develop solutions to the biggest company that handles public transportation ticketing in Latin America, called Autopass, there I developed a system where other companies could recharge their employees cards to use the public transportation to go work. Now in 2024 I’m open to new opportunities because the contract with the client has ended because the project was successfully delivered. I also have some experience in leading and managing other developers in the past 3 years, being responsible for code review, defining technologies and frameworks and respecting all the requisites from the board level. I mainly worked with these stacks: ● Backend: ○ (6+ years) Node.js in TypeScript(Nest.JS, GraphQL, Prisma, Express.js, Firebase, Joi) ○ (2 years) Python for minor tasks. ○ (6+ years) Relational databases: PostgreSQL and MySQL. ○ (6+ years) Non-relational databases: DynamoDB and Firestore. ○ (6+ years) Unit and integration testing: Jest and Mocha. ● Frontend: ○ (6+ years) React.js in Typescript(Next.JS, GraphQL, Material-UI, React Hooks and Redux) ● Cloud/DevOps: ○ (6+ years) Docker for expanding features and services such as ElasticSearch. ○ (6+ years) AWS(Lambda, SQS, S3, RDS, SNS, ECS, Cognito, API Gateway, CloudFront, 53 and Chime). ○ (3 years) GCP(Firebase, Cloud Functions and Bucket) ● Agile methodologies: Scrum and Kanban
