I am Md. Tamimul Ehsan. But you will find me everywhere with handle name Tamim Ehsan. I'm currently working at Nanyang Technological University as a Research Engineer in the Alibaba-NTU Global e-Sustainability CorpLab. I work closely with researchers at VectorDB-NTU and engineers at Alibaba DB to develop next-generation vector database technologies through a joint industry–academia research initiative. Previously, I worked on Opal, Optimizely's agent orchestration platform, where I gained extensive experience in building agentic AI systems, orchestration frameworks, and the infrastructure that powers them. I've completed my undergrad on Computer Science & Engineering at BUET. Besides tech I'm also fairly invested in movies & animes, reading, and travelling.

💡 I'm open to new opportunities in the domain of backend engineering, systems, vector databases
