As a Full Stack Developer with a primary focus on backend development, I am responsible for the complete lifecycle of creating new features within a distributed architecture system consisting of over 50 microservices. My responsibilities include talk to the product owner to gather requirements, planning the microservice by selecting appropriate patterns and technologies, coding the microservice, deploying it, and ensuring the delivery of high-quality results throughout the entire process.Achievements:> Suggested, planned, and led the rewrite of a crucial part of the system responsible for generating important information. This resulted in over 35% savings in overall infrastructure usage and reduced the average information generation time from 1200 milliseconds to 300 milliseconds;> Created a complex group of high-speed microservices for positioning and velocity calculations using mathematical concepts and JavaScript lifecycle optimizations in Node.js, leading to a significant feature within the system that attracted new clients to the company;> Developed a frontend page that collects coordinate points from a map, processes the positions on the edge (user’s browser), and sends them to the backend to save routes and targets represented by coordinates. This was achieved through using strategic hooks within the React library, resulting in a highly performant page that operates on-demand that stop consuming 300 mb to only 57 mb of the user’s browser memory RAM;> Refactored a microservice that originally used an average of 50 Kubernetes pods to only 5 pods. I Achieved this by leveraging advanced Node.js features and implementing caching algorithms using Redis.Stack: Node.Js | React.Js | Next.js | Docker | Kubernets | TypeScript | JavaScript | MongoDB | Redis | RabbitMQ | MySQL | PostgreSQL | GraphQL | TestcontainersAWS Services: EC2 | EKS | ECS | ELB | SES | S3 | Lambda | IAM | VPC with Subnets, Internet Gateway, Route Tables, NAT Gateway, and Security Groups

Curitiba, Paraná, Brasil

As a Full Stack Developer, I was responsible for managing all technical aspects of the projects assigned to me. This included designing and implementing RESTful and GraphQL APIs, developing complex frontend pages with a focus on performance and optimization, and extensively leveraging AWS services to deliver robust and scalable solutions.Achievements:> Developed a complex word search system for text data on the backend and integrated this feature on the frontend through a fluid and optimized client-side search field. This resulted in highly accurate and performant searches that greatly enhanced the user experience;> Refactored a legacy API, transforming it into a well-architected backend-for-frontend for a mobile application using clean architecture, resulting in a highly maintainable API that facilitated quick bug fixes and the agile addition of new features throughout the project lifecycle;> Led a cloud architecture migration, moving all services to AWS and transforming them into serverless functions using AWS Lambda, resulting in significant cost savings, increased stability, and improved response times.Stack: Node.Js | React.Js | TypeScript | JavaScript | Docker | PostgreSQL | MongoDB | GraphQLAWS Services: Lambda | RDS | SNS | SES | S3 | Cognito | API Gateway | EventBridge | App Sync | Amplify | CloudWatch | Rekognition | IAM
