Who am I?
👋 Hi, I’m Ada He — a backend engineer specialising in Java and Go (Golang), with some C/C++ experience.
🎓 I’m currently pursuing a Master of Information Technology with a Bachelor’s in Computer Science. I bring prior full-time experience at Huawei Technologies and Garena, where I worked on system reliability, automation, and scalable infrastructure.
💻 My core interests are distributed architecture, software design, and back-end performance optimisation. I’m proficient in Go/Java concurrency (Threads, GMP model, Go/Java performance optimisation), Cloud Native (Docker, Podman, Kubernetes, Istio), and back-end development (Spring Boot, Spring Cloud, gRPC, Etcd, Kafka, Redis, MySQL). I’ve also independently designed microservice frameworks based on Etcd and gRPC and built scalable automation platforms used by thousands of servers.
🛠️ Highlights:
- 📉 Reduced crash rate for the OpenHarmony OS to <0.05% by solving 50+ reliability issues and building a binary-search-based automated testing tool in Go.
- 🚀 Boosted throughput from 5000 QPS to 12000 QPS for an operations automation system by refactoring it to Microservice architecture.
- 🔥 Built a scalable multi-channel alerting system as an SRE tool supporting async messaging, failover, and timed dispatch with <1s deviation.
- 🔧 Strong in resolving concurrency issues and system bottlenecks using tools like pprof, structured logs, and JVM optimisation.
- 📚 A strong believer in continuous learning and self-improvement. Books I’ve read include Site Reliability Engineering, High Performance MySQL, and Future Architecture: From Services to Cloud Native.
What’s this website for?
This is my personal website, which was originally created for sharing my notes and process of troubleshooting. The purpose of creating such a website is to prevent myself from forgetting what I know or making the same mistakes again, and to help others avoid making the same mistakes I did.
Please note that this is not a tech blog. At most times, I will post some articles and notes about software development and software design here. I’ll regularly post something not related to technology here as well.
This is a static website that is based on Hexo, open-sourced on GitHub, and hosted on Vercel.
