About Me.
With more than 15 years of expertise in software research and development, I have a lot of baggage developing and maintaining Java, Python, C# and Golang applications, and ensuring seamless integration with other components and services. My work includes implementing APIs and backend services, focusing on scalability, security, and efficient resource management.
I also have experience with different resources like MySQL, Redis, MongoDB, Oracle, DynamoDB, Kafka. My work has focused on component-based architecture for improved maintainability and performance of APIs.
Lately I have been focusing in lead high performance teams that sustain and develop high critical and high value software to top market companies.
I believe in software for people. Software made by people to be used by people.
