Hi, I'm Daniel Lin.
I am a Senior Software Engineer operating as an Infrastructure-Led Full-Stack developer. I specialize in architecting event-driven microservices and executing zero-downtime migrations under high-growth traffic, while delivering seamless end-to-end product experiences. Below are the architectural challenges I've conquered.
Featured Engineering Deep Dives
Zero-Downtime Migration & Scalable EDA
Optimized DB performance by 15x and executed a 4-phase zero-downtime migration, scaling to 100M+ requests.
Observability & Dev Tools
Engineered React & Node Feature Toggle SDKs and an AOP tracing library, slashing MTTR across 30+ microservices by 90%
Clean Architecture in Go Microservices
Architected 6 highly concurrent Go microservices using strict Dependency Inversion and custom in-memory TST algorithms.
Cloud Infra & Zero-Trust K8s
Provisioned reproducible GKE environments via Terraform, enforcing a Zero-Trust network perimeter and secure CI/CD.
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."
