Hi I'm Hanoak

Senior Software Development Engineer @ Contentstack · Backend Product Engineering

👨‍💻 About Me

I'm a backend-focused product engineer who takes complete ownership of the work I do. Over the years I've grown from full-stack LAMP development into building scalable, event-driven backend systems on Node.js and AWS.

  • 🔭  Currently building backend systems at Contentstack — serverless AWS architecture, marketplace apps, and developer tooling.
  • 🌱  Always exploring new technologies and going deeper into distributed, cloud-native systems.
  • 📦  Author of contentstack-webhook-verify — a zero-dependency npm utility for cryptographic webhook signature verification, replay-attack prevention, and multi-region support.
  • ✍️  I teach and share what I learn — blogging on Medium and creating courses/videos on Udemy and YouTube.
  • 📫  Reach me on LinkedIn.
