• Helped rewrite many cool JVM (Kotlin-heavy) back-end systems related to the core products to make them fresh, faster, and more reliable.

Currently, mainly focused on foundational/architectural work, such as:
• Spearheaded the migration of core Java back-end systems to the latest stack, and the wide adoption of standardized code practices, enhancing system performance and reliability.
• Worked with CI and CD optimizations, substantially reducing build and deployment times, thereby boosting team productivity.
• Drove significant improvements in our async (Temporal-based) workflows, including full-scale migrations, optimizations, and bug fixes, leading to cost reductions, and enhanced documentation.
• Conducted comprehensive research and experimentation with performance testing tools such as k6 and Artillery, laying the groundwork for a more distributed and effective load-testing approach in the company.

• Working with highly efficient Spring Boot microservices, Kafka, and AWS to build solutions for the financial advisory industry.
• Helped reduce build time execution of team’s microservices by +50% through rewriting and refactoring +650 tests, plus migrating them from JUnit to Spock (with Groovy) for a better BDD.
• Helped documenting the Postman API ecosystem of the company to improve QA assertion and help onboarding new team members.
• Helped to build a Spring Security policy-based authorization microservice (along with OPA and Rego) to allow more robust decision-making for the systems’ permissions in general.
