About

Sr Java Software Engineer

I am a seasoned software engineer specializing in Java backend development, with a proven track record of delivering robust solutions for major clients in the entertainment and manufacturing industries. My expertise spans working with legacy monolithic systems and leading successful migrations to modern microservices architectures using technologies such as Spring Boot, Spring Framework, and Java (6–21). I have collaborated closely with interdisciplinary teams, ensuring seamless integration of backend team with frontend, QA, DevOps, and business stakeholders.

Key Experience:
- Migrated financial ERP systems for brokers from monolithic to microservices, improving scalability and maintainability for major global enterprises in the entertainment and manufacturing sectors. Leveraged Apache Kafka for event-driven communication and AWS services (DynamoDB, ECS, ECR, CloudWatch) for cloud-native deployments.
- Led query optimization initiatives that significantly improved user experience, reducing screen load times to a fraction of previous durations. Worked extensively with Oracle databases and PL/SQL to enhance performance and reliability, including maintaining and optimizing complex stored procedures that held critical business logic.
- Developed a revenue recognition microservice for a leading entertainment company, automating a previously manual process performed by the financial team in Excel. This solution handled complex rules for product bundle usages and ensured timely, accurate revenue recognition, supporting high-performance data processing with reactive programming (WebFlux, RxJava).
- Currently maintaining and enhancing the accounting platform for a major theme park operator, ensuring reliability and compliance.

Additional Skills & Background:
- Proficient with CI/CD tools including Jenkins, Harness, and Azure DevOps.
- 15+ years of Linux experience, comfortable with system administration and troubleshooting.
- Experienced with Docker for containerization and deployment.
- Bachelor’s degree in Information Systems Engineering, providing a strong foundation in business analysis and technical communication.
- C1 level English proficiency; extensive experience working with international and remote teams (Mexico, USA).
- Strong preference for backend development, with deep expertise in enterprise Java and system integrations.
- Proactive in proposing and driving software development process improvements.

I bring strong problem-solving skills, deep knowledge of enterprise Java, and hands-on experience with complex system integrations. I am ready to help your company modernize, scale, and optimize your backend systems.
