Tech Stack & Expertise
Backend & Architecture
Cloud & Infrastructure
Hi, I'm Daniel Lin.
I build systems that scale. I specialize in architecting event-driven microservices and executing zero-downtime migrations under high-growth traffic. Below are the architectural challenges I've conquered.
Featured Engineering Deep Dives
Zero-Downtime Migration & EDA
Rebuilt a legacy monolith into a TypeScript Core Order engine supporting 4 countries, handling 1,200 RPS.
High-Concurrency Infrastructure
Engineered independent WebSocket gateways and Feature Toggle SDKs to protect core APIs from thundering herds.
Domain-Driven Design & K8s
Built a secure, high-concurrency microservices ecosystem from scratch utilizing Go Generics and Terraform.
Engineering Philosophy
"My core engineering ethos are based on three things:
First, I approach every challenge as The Pattern Seeker. I love diving into ambiguous, messy problems and won't stop until I break them down and find the underlying pattern.
Second, I'm a Lifelong Learner. I’m always eager to pick up new tech to keep my skills sharp.
Finally, I believe in Integrity and execution. That means being authentic—I don't make promises I can't keep—and demonstrating resilience by quickly learning from any setback. Plus, I always ensure the team gets the credit they deserve."
