• Designed and deployed the system architecture on Alibaba Cloud (ECS + RDS), including environment setup for Python (Flask), PHP-based internal gateway service, FileMaker Server, Apache, and MySQL.

• Independently analysed and reverse-engineered the legacy codebase with no handover documentation, restoring system logic across PHP–FileMaker–Python layers.

• Solved complex API integration issues: enabled communication between PHP Gateway, FileMaker Data API (v1/v2), and Python algorithm service using JSON over HTTP.

• Managed server-side challenges including port conflicts, firewall rules, and non-SSL data transmission; ensured stable multi-service deployment on a single ECS instance.

• Developed and maintained over 60 backend APIs, wrote comprehensive documentation with usage examples for frontend teams, and supported cross-team debugging.

• Improved system concurrency by ~80% through session optimisation, Redis-based caching, and ECS log analysis, significantly reducing crash risks under high-frequency API access.

• Regularly collaborated with frontend developers to clarify API behaviours, update functionalities, and resolve integration issues.

• Developed three company websites using React, WordPress (Elementor & Full-Site Editor), and custom code.

• Created a responsive React SPA to showcase products and research, optimised for SEO and performance.

• Built a content-rich WordPress site via Elementor, refined layout and responsiveness with custom CSS.

• Extended WordPress Full-Site Editor with custom CSS animations, JavaScript, and PHP to enhance interactivity.
