Work Experience
Senior Software Engineer
2023 - PRESENT
Stone
- Designed and developed new systems to process instant payments more quickly, allowing the company to grow its client base.
- Migrated all the services to a new infrastructure using tools like helm/helmfile instead of a Shell script, which allowed us to be more productive, ship fast, and standardize the services.
- Managed to extract the correct data from the source to a big-data application so the data could be shown more quickly and assertively.
Technologies: Amazon Web Services (AWS), Go, gRPC, Kubernetes, Unit Testing, Terraform
Senior Back-end Engineer
2022 - 2023
Prota Games
- Engineered the first back-end service for the company's first game, developed using Go with Protobuf.
- Developed the CI pipelines using GitLab CI for automated tests, deployed using infrastructure as a code, and built and deployed back-end and game servers.
- Helped with the integration of the game server technology used with Amazon GameLift.
- Organized custom runners on Amazon using EC2 and ECS.

Senior Back-end Engineer
2021 - 2022
Wildlife Studios
- Developed an events management system to control segment events for the games, which reduced the amount of time, resulting in a profit increase for games.
- Managed a calendar system that defined scheduled events to know when they were happening or ending, either using an application programming interface, representational state transfer, remote procedure call, or listening to Kafka topic.
- Created a player segmentation system where people could define a set of rules using the player or game context properties. The rules were determined using a programming language subset, providing flexibility when creating the rules.
- Improved CI and CD pipeline to be more efficient by caching packages and changing the steps.

Software Engineer
2020 - 2021
Globo
- Created an optimizer model that aimed to improve the way companies sell advertising space on TV. The model guarantees the impact of your ad and the number of people that will see it in a specific time range.
- Developed a machine learning pipeline outputting the model results, which then had around 50GB size to our digital monitoring products.
- Designed a new infrastructure on GCP for a project that needed periodic pipelines and steps to run.

Software Developer
2019 - 2020
Guiabolso
- Developed the core systems for gathering user data that could potentially be from different banks. These systems were capable of collecting data from at least six other banks.
- Created an admin application to centralize all the other separated applications in one place, adding a more sophisticated authentication and authorization layer.
- Organized a faster way to get data from a specific bank, improving the user experience. The time to get data dropped from six minutes to less than one minute.

Junior Software Engineer
2018 - 2019
Beblue
- Created the customer's back end system, which included information such as sales revenue, sale details, and customer profile quality.
- Developed a conciliation service that takes an XLS file as input and matches it with the data. This allows the customers to see any differences between their property system and our system.
- Provided services that enabled customers to integrate their POS systems with ours, allowing them to give customers access to our products.

Experience
Kamui
https://thepabloaguilar.dev/kamui/This project consisted in making the use of KSQL simple for users. Instead of dealing with params, users can now create a new stream from a Kafka topic or by connection to another stream and apply the desired filters.
Deal – Protoc Plugin
https://github.com/faunists/deal-goA protoc plugin for generating consumer driver contract tests from JSON and YAML files for gRPC services and methods.
The plugin generates:
• A client to be used on the client-side to mock the responses based on the contract.
• A stub server is to be used on the client-side as the client above, but you should run it as another application.
• A server test function, where you pass your server implementation to the function process, will validate all the contracts.

Returns
https://returns.rtfd.io/The main idea is to bring the functional programming world to Python by providing a set of classes and functions commonly found in available programming languages but with other names to be easier to read instead of FP jargon.
