@ Wissen Technology (Macquarie Group)

• Built a RAG-based knowledge retrieval and LLM inference pipelines so new engineers can understand legacy modules and dependencies in minutes, not hours.
• Built messaging with 2 platforms (Solace PubSub+) on Java/Spring Boot for a high-volume platform; enabled real-time trade acks and position sync across 3 asset classes (equities, FX, derivatives).
• Automated bulk trade upload validation in Meteor/JavaScript, calling external REST APIs for settlement dates, restricted stock checks, and market calendars - fewer manual touchpoints and faster processing.
• Authored 4 doc types—architecture guides, API specs, implementation plans, and runbooks—so dev/support teams could move faster and with fewer escalations.
• Configured Claude Code using Amazon Bedrock, enabled sub-accounts, and created a SAM user for secure access. Built a CI/CD pipeline to automate deployment and manage inference profiles for streamlined model integration.

@ FIS Global

• Reduced system latency by 60% by designing and deploying high-performance reactive microservices using Spring WebFlux, enhancing client experience on the banking platform.
• Improved system reliability by resolving code vulnerabilities identified by SonarQube & Black Duck, ensuring secure and compliant releases.
• Boosted API performance and platform efficiency by developing and managing RESTful services, cutting processing time and improving throughput.
• Enhanced development agility by building REST APIs aligned with OpenAPI Specification standards, enabling 100% documentation consistency and faster integration.
• Streamlined development cycle by 40% through reusable backend components and standardized error-handling templates, improving maintainability.
• Achieved 85%+ unit test coverage using JUnit5 and Mockito, ensuring API robustness and reducing regression risk.
• Integrated Kafka consumers to process upstream service events and persist data reliably, contributing to real-time insights and system responsiveness.
• Improved cross-team delivery by coordinating deployments across Dev, SIT, UAT, and Production environments, ensuring smooth rollout and version control.
• Accelerated business workflows by delivering responsive web services for business account opening, enhancing user experience and backend integration.
• Maintained Agile delivery momentum by participating in sprint planning, stand-ups, retrospectives, & driving continuous improvement.
• Ensured release transparency by drafting detailed release notes for updates and maintenance deployments, supporting clear stakeholder communication.
