Hello,
I'm Shajan - a senior software engineer with 8+ years of experience building scalable backend systems, microservices, and developer tools. I specialize in Node.js, TypeScript, and cloud-native architectures that handle millions of requests reliably.
Beyond production systems, I love experimenting - whether it's tinkering with IoT electronics, building side projects, or automating things around the house. I also enjoy thoughtful design, capturing moments through photography, and writing about what I build and learn.
