Senior Backend Game Engineer

Companion Group,

Apr 2024 - Current (2 years 1 month)

In my current role as a Senior Backend Game Engineer, I’m contributing to the development of the next Gears of War 6 in collaboration with The Coalition Studio (Microsoft). I work closely with a globally distributed team to design and deploy scalable backend systems supporting complex multiplayer features, including matchmaking, lobby management, and real-time gameplay services. Using .NET Core, C#, and PostgreSQL, I architect and implement high-performance backend components optimized for reliability and scalability. I leverage Azure, Kubernetes, and Docker for cloud deployment and container orchestration, while maintaining Infrastructure as Code (IaC) through Bicep and GitHub Actions. To enhance system responsiveness, I’ve implemented Red

Senior Software Engineer

Perfect Storm Studios

Mar 2022 - Mar 2024 (2 years 1 month)

As a Senior Software Engineer, I designed and maintained scalable backend systems for a high-performance MOBA game, focusing on Unity, Azure, and multi-cloud integration. I developed RESTful APIs with .NET Core, leveraging Redis for distributed caching and PostgreSQL for persistent data. I implemented Kafka for asynchronous event streaming to handle matchmaking, in-game analytics, and player progress tracking. To ensure seamless scalability, I used Kubernetes and Docker for container orchestration and deployment automation, integrated with ArgoCD and GitHub Actions. I also applied gRPC to enhance cross-service communication and LINQ for efficient data querying. For internal tools, I used ReactJS and Angular to build admin dashboards that in

Lead DevOps Engineer

Rakuten,

Nov 2020 - Mar 2022 (1 year 5 months)

As Lead DevOps Engineer, I spearheaded automation initiatives, building standardized CI/CD pipelines and scalable cloud architecture across Azure, AWS, and GCP. I implemented Infrastructure as Code through Terraform and ArgoCD, enabling seamless, reproducible deployments. Using Kubernetes and Docker, I orchestrated containerized workloads, and employed Redis for caching and Elasticsearch for centralized log management. I also introduced Kafka for real-time log streaming and event-driven automation. My DevOps framework included multi-domain application monitoring with Prometheus and Elastic Stack, supporting both on-prem and cloud workloads. I coached engineers on using Dependency Injection to standardize deployment configurations and led in

Software Architect

Crossover for Work

Apr 2018 - Nov 2020 (2 years 8 months)

As a Software Architect, I led the design and deployment of scalable backend services using Node.js, JavaSpring MVC, and AWS cloud services. I leveraged GraphQL to streamline data access and enhance frontend communication, while employing Docker for containerized deployments. I integrated Elasticsearch and Redis for fast data retrieval and caching, improving system responsiveness under load. Using Jenkins for CI/CD, I automated pipelines across staging and production, establishing a strong DevOps / Infrastructure as Code foundation. For frontend projects, I utilized ReactJS and React Native, integrating LINQ-like query optimizations and Dependency Injection patterns within microservices for maintainability. These efforts ensured seamless co

Senac MS, Campo Grande e Região

Dec 2016 - Apr 2018 (1 year 5 months)

As a Solution Architect, I played a central role in designing and deploying a comprehensive "Educational ERP" system, tailored to serve 27 states across Brazil. This ambitious project required a well-coordinated architectural strategy, which I developed in collaboration with a small team of solution architects. We focused on establishing a robust Application Lifecycle Management (ALM) process through Team Foundation Server, creating a seamless workflow for version control, testing, and deployment across environments. To ensure scalability and maintainability, I implemented Domain-Driven Design (DDD) principles, building a resilient foundation for a system that could grow with the organization’s needs. A major challenge in this project was f

Senior Software Engineer

Unimed Campo Grande,

Jan 2014 - Nov 2016 (2 years 11 months)

In my position as a Senior Software Engineer, I was responsible for the development and maintenance of a critical healthcare application using ASP.NET MVC and Entity Framework on the server side, paired with a rich frontend built with JavaScript, TypeScript, AngularJS, and Bootstrap. My role extended to code quality assurance and testing, utilizing Microsoft’s unit testing tools to ensure that both backend and frontend components met high standards of reliability and performance. As a senior team member, I led the charge in refactoring the codebase, applying best practices and design patterns to improve maintainability and scalability. One of the primary challenges I tackled was managing the complex requirements of a healthcare system, whic

Software Developer

Espaço Vip,

Jan 2009 - Dec 2013 (5 years)

Espaço Vip was where I began my career in software development, gaining hands-on experience in building a point-of-sale (POS) system from scratch. Working with C# and Windows Forms, I developed an application that provided a graphical interface for sales transactions, paired with Microsoft SQL Server as the database backend. I also implemented reporting features using SQL Server Reporting Services (SSRS), enabling store owners to view and analyze their sales data. This role involved gathering requirements directly from clients, translating them into functional features, and iteratively improving the software based on user feedback. One of the early challenges I faced was ensuring data integrity across multiple locations, as the POS system w
