MD Kamrul Hassan

Senior Software Engineer at Optimizely

I own backend services for Opal, Optimizely's AI agent platform — agent and workflow orchestration, tool calling, and agent memory and retrieval — along with the platform infrastructure underneath: Cloud Run and Cloud SQL in Terraform, an event bus split into isolated brokers, and zero-downtime data model migrations.

Outside work I build developer tooling — terminal CLIs, Neovim plugins and orchestration for AI coding agents. I write about what I had to learn the hard way, some of it in Bengali.
