William Huang

I'm a Senior Full Stack Engineer with 12 years of experience building scalable web and mobile applications across diverse industries including travel, aerospace, and healthcare. My core strength lies in delivering end-to-end solutions — from designing intuitive user interfaces to building resilient, high-performance backend systems — all while prioritizing maintainability, security, and user experience.

Career Highlights:

• Amex GBT Egencia (Senior Software Engineer)
  I helped scale Egencia's travel platform to handle peak booking periods with thousands of concurrent users. I redesigned monolithic systems into microservices, implemented micro-frontends for modular UIs, and integrated real-time updates using WebSockets. I also worked closely with ML teams to expose AI-driven recommendations and fraud detection as backend APIs, and built observability dashboards to monitor booking traffic in real time.

• FlightAware (Full Stack Engineer)
  At FlightAware, I worked on high-throughput data pipelines ingesting global ADS-B and weather feeds. I led the development of real-time flight tracking UIs and a 3D airspace visualization tool using Unity3D. My work helped improve flight tracking accuracy and powered dashboards used by air traffic analysts and airline partners.

• Oscar Health (Software Engineer)
  I engineered backend services for HIPAA-compliant virtual care, focused on reliability and security. I introduced caching layers, improved video consultation performance using WebRTC optimizations, and built APIs with strong authentication and access control policies.

Technical Interests:

• Scalability & Architecture: I enjoy solving performance bottlenecks, refactoring large codebases into microservices, and optimizing distributed systems for high availability and low latency.

• AI/ML Integration: I have a growing interest in ML applications, particularly how AI can enhance user experience through personalization, anomaly detection, and automation.

• Developer Productivity & DevOps: I'm a strong advocate of CI/CD pipelines, IaC with Terraform, and observability practices using Prometheus and Grafana.

• Frontend Engineering: I keep up with modern frontend trends, including micro-frontends, design systems, and accessibility standards like WCAG.
