Sh Lin
Software Engineer
Taipei, Taiwan
Summary
👤
SeniorSh Lin is a pragmatic backend engineer with 13 years of experience building high-throughput web applications, primarily in Ruby/Rails and increasingly in Go. Based in Taipei, he has a strong track record optimizing OLTP systems and cloud infrastructure on GCP/AWS, from reducing MySQL hotspots and cutting VM costs via spot instances to designing payment and subscription platforms with robust state machines and failover. He’s delivered practical engineering wins—Redis-based atomic inventory control with Lua, a native C-extension ID generator port, and a self-routing Varnish cache cluster—that noticeably improved capacity and reliability. Comfortable across system design, performance tuning, and log/CI pipelines, he pairs hands-on coding with infrastructure pragmatism. Despite describing himself modestly as "yet another ordinary coder," his work consistently targets measurable operational improvements.
