Chia Chuin Kee

- Designed and implemented distributed Java/SOFABoot backend services — navigating complex relational schemas and transactions — across payments, refunds, settlements, FX, and cross-border fund movement over ~2 years. - L1 owner of 3 microservices and L2 of 17+ others across a 20+ service payment flow spanning order creation, channel integration and settlement. - Cut a critical batch-processing bottleneck in the payment flow from ~25 h to ~5 h (5x) by optimizing scheduling and data-access patterns. - Onboarded a major e-commerce merchant processing high-volume cross-border transactions monthly. - Authored standardised docs for 15 RESTful APIs (specs, error handling, code samples); deprecated legacy fields to simplify maintenance. - Maintained 90%+ unit/integration test coverage and 100% pass rate as a merge gate, reducing regression risk across owned services. - Built and refined monitoring/alerting for critical payment flows, surfacing issues before merchant impact. - Every release shipped on-schedule (≤ 1 wk variance) with zero production incidents. - Authored 3 reusable Claude Code skills and 3 knowledge bases to codify team workflows and eliminate repetitive manual tasks. - Applied AI tooling across the SDLC — backend implementation, code review, production debugging — as a daily workflow accelerator. - Mentored junior engineers through a 3-month onboarding program; all passed probation review and ramped to independent contributors. - Trained ~50 stakeholders on API standards; consistently received feedback praising technical depth and clarity.

- End-to-End Automation: Built a Python-based backup system for Jira, Confluence, and Bitbucket using Poetry/Pyenv, automated via Cron on EC2 to eliminate manual intervention. - Cloud Infrastructure: Leveraged AWS S3 for encrypted storage and SNS for real-time status alerts, ensuring scalable and secure data retention. - System Reliability: Implemented exponential-backoff retries and robust error handling to guarantee high availability; optimized API request patterns to stay within Atlassian rate limits. - Built and shipped client-facing web applications end-to-end — frontend UI, APIs, and database schema design — across a 2.5-year engagement.

- Performed product demonstrations to expand the client base and translated business requirements into technical functional specs. - Contributed to credit scorecard modeling/validation, data preparation, and regulatory capital requirement computations.

Awards: - Edinburgh Global Undergraduate Mathematics Scholarship (3 years in a row). - Rapid Formations Entrepreneur Scholarship (top 20 out of hundreds of UK's & USA's students). - Genting Malaysia Full Overseas Scholarship (declined). - Government Full Scholarship (accepted).
