Work History

Lead engineering execution for internal platforms, AI-driven tools, and digital product initiatives across a media platform, working closely with QA, Growth, SEO, and executive stakeholders.

• Lead a team of 5 engineers across internal platform and digital product delivery, owning sprint planning, task ownership, and execution quality
• Introduce AI-assisted development workflows using Claude and Cursor — sprint velocity increased by ~38% over 3 months (measured by story points completed per sprint in GitLab, comparing 12-week pre/post adoption period)
• Reduce p95 API response time by 45% (from ~900ms to ~490ms) through Redis caching layer and CDN optimisation, measured via Tencent Cloud APM dashboards over a 30-day pre/post window
• Cut CI/CD pipeline build and deployment time from ~50 minutes to ~12 minutes by restructuring GitLab pipeline stages and introducing parallel jobs (measured by GitLab CI job duration logs)
• Automate daily editorial analytics reporting — reducing manual reporting effort from ~3 hours/day to under 20 minutes via GA4 pipeline (measured by team time-log comparison before/after dashboard launch)
• Architect scalable backend services and modern web platforms on Tencent Cloud using Node.js, NestJS, MongoDB, Docker, and GitLab CI/CD
• Collaborate with QA, Growth, SEO, Finance, and executive stakeholders to align engineering execution with business priorities
• Mentor engineers through regular feedback and technical reviews, improving delivery consistency and engineering ownership

Delivered business-critical fintech platforms supporting payments, wallet services, partner operations, and enterprise transactions.

• Deliver end-to-end development across design, implementation, testing, deployment, and maintenance for payment and wallet platforms
• Maintain 99.95% API uptime across payment and wallet services, handling 15,000+ daily transactions with consistent p95 response time under 150ms (measured by internal uptime monitoring and APM dashboards)
• Reduce API integration defect rate by ~52% after TypeScript migration and OpenAPI contract standardisation (measured by QA defect tracking system comparing 6-month pre/post periods)
• Build scalable applications using React, Next.js, Node.js, TypeScript, Cassandra, and PostgreSQL with OpenAPI-based service contracts
• Standardize engineering practices through TypeScript adoption, API design improvements, and reusable component architecture
