Albert Xu

I am Albert (Geyang) Xu, a full-stack software engineer with experience in backend, web, and systems development. I hold a Master’s degree in Computer Science from the University of California, San Diego (GPA: 3.88/4.0) and a Bachelor’s degree in Computer Science from the University of Liverpool (GPA: 3.93/4.0, top 3%).

Currently, I work at 4Pexonic Inc. in San Diego as a Back-end Engineer, where I built a one-stop research-to-publication platform using Go microservices with gRPC/REST and NATS JetStream. I implemented ElasticSearch for full-text search optimization, constructed multi-stage Docker builds with zero-downtime CI/CD pipelines, and integrated Redis caching to significantly improve system performance. Previously, I contributed to the development of GovChat at Spesland, an AI-driven government platform deployed across 200+ cities, where I implemented real-time LLM microservices, secure authentication, and production-grade CI/CD workflows.

Earlier roles include Web Developer at UCSD’s ECE Department, and Research Engineer at the Halıcıoğlu Data Science Institute, where I worked on data quality and fairness frameworks for machine learning systems.

My tech stack includes Python, Java, Go, SQL, JavaScript, Django, React, Node.js, Docker, AWS, and gRPC. I’m passionate about delivering robust, high-performance systems and writing clean, maintainable code.
