High Performance Trading Systems: Developed and optimized for the components of the Multi Matching Engine (MME - a high-performance trading engine) using Java, Spring framework, and reactive patterns, to enable automatic trade execution for 10M+ daily transactions across forex, equities, and crypto markets.

• Cloud-Native Deployment: Containerized services with Docker and orchestrated deployments on Kubernetes/Amazon EKS, reducing infrastructure costs and improving system uptime.
• CI/CD Automation: Contributed to migration from TeamCity and wrote GitLab CI/CD pipelines for artifact publishing, vulnerability scanning (Prisma, SonarQube, Sonatype), and deployment, reducing build time.
• Infrastructure-as-Code: Customized the Operations framework called MOE (MME Operating Environments) for customer-specific Amazon EKS deployments, designing partitioned Helm layouts that significantly reduced deployment setup time for LATAM client onboarding.
• Customer Adaptations: Delivered 15+ adaptations and customizations (CRs) for 3+ customers across LATAM, US, and EU to deliver tailored solutions addressing unique requirements, including leading onsite acceptance testing from the development side in Colombia for an equity trading platform handling $500M+ daily volume.
• Security & Testing:
  • Patched 50+ vulnerabilities in dependencies, reducing Sonatype threat scores from 9 → 1.5, enhancing supply chain security.
  • Identified and resolved compatibility issues in unit testing frameworks that revamped 2,500+ JUnit/Mockito test cases, achieving 90%+ code coverage.
  • Designed checkstyles and established coding conventions to ensure high-quality code standards.
• AI-Driven Efficiency: Utilized GitHub Copilot to draft technical documentation (Javadocs, Confluence pages) and boilerplate code (DTOs, repetitive logic), and generated 350+ unit tests with Diffblue Cover, increasing code coverage significantly and enhancing code reliability.
• Streamline Workflows: Administered tools like TaskTop integration, repository access management, and CI/CD pipeline automation for seamless builds and deployments.

Engineered and modernized capital markets and payment software solutions for financial institutions using Java, Spring Boot, Python Flask, Docker, Apache Camel, CXF, Informix, Orika, and MapStruct.

• Zeus-GPI (General Process Interface for ISO 20022): Developed SOAP and REST APIs to route financial messages (Swift MT/MX, ISO 20022) between databases, message queues, and other endpoints, enabling seamless integration for 5+ investment banking customers.
• CMS (Card Management System): Migrated legacy Pro*C code to a modern Java-based architecture with Spring Boot and Spring Cloud. Developed REST APIs for corporate card payments, serving 5+ banks and payment processors.
• CapSuite: Designed an automation tool to generate code for entities and mappings based on SQL procedures and Swift MT/MX definitions, improving developer efficiency.

• Developed Apache Camel-based message routing and gained exposure to investment banking processes.
• Built an Employee Attendance Management System using Java, JDBC, and MySQL.
