Goal: System Design, Development and Maintenance to improve Sales and Operation Planning Tools (S&OP Tools).Challenge: Processing large volumes of data in a distributed environment to provide easy-to-use solutions for business analysts in order to predict staffing hiring and allocations.Technologies: Java, Spring Boot, Microservices, Event-Driven Architecture, Systems Design, PostgreSQL, Golang, Python, New Relic, Kibana, Grafana, Fury (Internal Platform that provide cloud native services).

As a Software Engineer, I worked with:- Delivery of new features and improvements in a product with microservice oriented architecture, working in all stages of the software development cycle (Full Cycle Development), from analysis, modeling, implementation, homologation, delivery, monitoring and support.- Case studies through research and POCs (proofs of concept) to validate the application of architectures and technologies in the problems faced during the project.- Preparation of technical documentation for the microservices ecosystem, such as architecture diagrams (following the C4 Model and UML) and RFCs.Contributions:- Support the development of an internal tool to increase efficiency and scalability of the work of logistics operations analysts, following a microservices oriented architecture to ensure future scalability and extensibility for other modules.- Asynchronous integration with a data science service for planning operational optimizations in logistics, through the application of the Workqueues Service from the Fury Platform (internal PaaS of the company), enabling scalability in the execution of these optimizations in parallel by the analysts of the company's logistics operation.- Migration of excel spreadsheet reading library to solve an application (developed in Springboot) memory issue, enabling execution of larger and more complex spreadsheets during the optimization process.

As a Software Engineer outsourced to a digital bank (Agibank), I was able to contribute with:- Development of applications for orchestrating banking operations (transfers, withdrawals, and generation of payment reports) through the implementation of event-oriented architecture using Springboot, Kafka and RabbitMQ.- Development of a business process model (BPM) for customer notification and recovery through orchestration via Camunda Platform, enabling the recovery of hundreds of customers with reduced operating costs.- Support for more than 40 applications in an microservices ecosystem, answering calls, adding more features and improving their scalability and availability.- Conducting small training sessions for the new team developers (and also the team responsible for the banking core) regarding the architecture used in the project.- Application of agile methodologies (Scrum, later migrating to Kanban).

I had the opportunity to attend the Cloud Native Development training for 5 months to prepare myself to be allocated to a client company, where I was able to learn through mentoring of software architects, and developing several applications performing several operations common to Cloud Native development, such as:- Implement and provision microservices in several programming languages (Java, Golang, Python) using Netflix technologies, such as Eureka Service Discovery to orchestrate communication between microservices, Ribbon to implement Client Side Load Balancer, and Hystrix to implement a Circuit Breaker, delivering completely scalable and fault-tolerant applications.- Provision and deploy docker images using Ansible, Packer and Jenkins pipelines.- Provision many tools inside virtual machines with Vagrant, such as Redis, ElasticSearch, Cassandra and Kafka (Zookeeper and Kafka brokers).- Implement stress tests with Gatling.- Deploying applications on Kubernetes Minikube.- Scripts in Python and Shell for sending slack notifications, automating deployment on EC2 instances, among other tasks.- Deployment and integration of ELK stack (ElasticSearch, Logstash, Kibana) with backend application to provision Observability.

Porto Alegre, Brasil

Serving the Brazilian Army, I attended the CFOR (Reserve Officer Training Course), designed to train Aspirant Reserve Officers. During the training year, I was able to develop several soft skills in the short term that benefited my work in the software development industry in the long term, through overcoming challenges and technical training in several areas of knowledge.
