Hi, I’m Jeffrey Zeng, a Senior Software Engineer who thrives on building scalable, reliable systems and solving hard problems. Over the past decade I’ve designed, built, and operated large-scale production software at industry-leading companies, delivering robust solutions and a strong developer experience. I enjoy collaborating across product, design, and operations to ship features that move the business forward while keeping systems resilient and maintainable. I specialize in end-to-end software delivery—from requirements and architecture through deployment, monitoring, and maintenance. I apply solid engineering principles (SOLID, DRY, YAGNI) and leverage AI/ML tools in production workflows. I mentor engineers on best practices, drive observability and incident response improvements, and strive to keep latency low and reliability high across multi-service platforms.…Hi, I’m Jeffrey Zeng, a Senior Software Engineer who thrives on building scalable, reliable systems and solving hard problems.
