Hello! I'm

Chaopin Wen.

I build things for the web.

Results-driven Software and DevOps Engineer with a strong track record of building scalable web applications and automating cloud infrastructure on AWS. Proficient in designing CI/CD pipelines (GitHubActions), orchestrating containerized microservices (ECS), and implementing infrastructure as code (CloudFormation). Proven success in reducing deployment downtime, cutting release cycles by 40%, and leveraging system monitoring (CloudWatch) to ensure reliable, low-downtime deployments across eCommerce, logistics, and real-time systems.

01. ABOUT

I'm Chaopin Wen, a DevOps-focused Full-Stack Engineer with over 9 years of experience delivering scalable, automation-driven solutions across logistics, eCommerce, and enterprise operations. With a background in Electrical and Computer Engineering, I specialize in building reliable infrastructure, automating deployments, and integrating AI into real-world systems to drive operational efficiency.

Proficient in JavaScript (React, Node.js), Python, and PHP (Laravel), I've architected full-stack applications and orchestrated microservices using AWS ECS Fargate, CloudFormation, and CI/CD pipelines (GitHub Actions). At Unis Fulfillment, I led the development of an AI-powered Yard Management System with real-time truck tracking, OCR-based container verification, and robot patrol automation—reducing manual processes and boosting warehouse visibility.

From optimizing pet food subscription platforms to deploying autonomous robots, I thrive at the intersection of system automation, infrastructure scalability, and developer productivity. I’m equally passionate about frontend architecture—building modular, reusable UI systems and streamlining team workflows through CI/CD and containerization.

When I'm not automating workflows or debugging edge devices, I'm probably cycling up mountain trails or jamming on the drums.
