Mateus Mendonça

Spearheaded the development of accelerator tools to streamline complex data migrations between multi-account AWS environments and Customer Data Platforms (CDP). Architected and delivered internal tech products leveraging Data Mesh principles and Event-Driven Design to empower the bank's data community with secure, decentralized data domains. Engineered highly scalable, serverless microservices in Python and Go, rigorously applying Hexagonal Architecture, Clean Architecture, SOLID, DRY, and KISS principles to ensure maintainability. Orchestrated robust data integration workflows and ETL pipelines utilizing AWS Step Functions, AWS Glue, and AWS Lambda to optimize data ingestion across the platform. Ensured strict governance, security, and end-to-end observability across the data infrastructure using AWS KMS, CloudTrail, CloudWatch, X-Ray, Datadog, and Grafana.

I've worked on developing scalable solutions that optimize the user experience on the platform, with a direct impact on millions of people every day. I worked on the evolution of the search engine and the development of high-availability microservices, focusing on performance, resilience and scalability. My stack included Java (Spring Boot and Quarkus), Node.js (Fastify), TypeScript, MongoDB, Redis, Elasticsearch, as well as GraphQL with Apollo Federation and Restful APIs. I have solid experience with asynchronous messaging (RabbitMQ, Google Pub/Sub), as well as working on system observability using Datadog and Grafana. In the infrastructure pillar, I work with Google Cloud Platform (GCP), MagaluCloud, Kubernetes and ArgoCD, applying DevOps and GitOps practices to ensure continuous, secure and scalable integration and deliveries.

I worked on the SRE (Offer Registration System) support team for the CVM (Securities and Exchange Commission), where I was responsible for maintaining and developing a complex system. I worked with various technologies, including Angular.js, jQuery, HTML5, CSS3, and JavaScript on the front end, and Java EE, VRaptor, Quartz, Jacoco, Liquibase, EJB, and Javax APIs on the back end. One of the main challenges was leading the migration of the system from Java 8 to Java 11, requiring in-depth technical knowledge and careful code refactoring. In addition, I managed the SQL Server database, ensuring efficient queries and data integrity.

▪ Developed and contributed to the development of highly scalable programs in software for the construction industry, playing a pivotal role as a software engineer intern supporting the operations of the User Insights development team. ▪ Designed new features of a platform that efficiently solves the challenges of planning, monitoring and analysing data, many of them coming from customer feedback. Gain hands-on experience translating user requirements into working software solutions. ▪ Worked closely with teammates to ensure a seamless user experience, actively participating in the integration and communication between the back end and front-end. ▪ Explored Docker technology. Used it as a containerization platform to facilitate the development and deployment of our applications. ▪ The software I helped to develop has been used by more than 200 companies and has served more than 1,000 users in the construction sector, optimizing the management of more than 2,600 construction sites. The aim of the software was to provide an efficient and effective approach to the sector by streamlining the planning of works with the line of balance and the monitoring of works.

▪ Designed a comprehensive web application tailored to the management of co-working spaces, events and individual user diaries, with seamless check-in and check-out functionality. Developed in HTML, CSS, JavaScript, PHP, jQuery, and MySQL to ensure a robust and dynamic user experience. ▪ Specialized in overseeing user data, internal information, events, and payments specific to managed co-working spaces within the software. ▪ Collaborated in the creation and maintenance of the database according to specific requirements. ▪ Worked with Docker for efficient application deployment. ▪ Implemented and maintained automated test with Robot Framework.
