About Tanvir Ahamed
I’m a software engineer specializing in AI applications and backend development. My experience spans application interfaces, API design, authentication, databases, and cloud deployment across teams in Japan and Bangladesh.
Background
At AIZOTH Inc. in Tsukuba, Japan, I develop applications that connect language models with software workflows. My work includes AI agents and document-grounded retrieval, together with the FastAPI services, Flutter interfaces, and Google Cloud infrastructure needed to make those features part of an application.
My foundation is backend engineering. At eSRD-Lab in Dhaka, I worked on education and clinical data platforms, developing APIs with Django and Flask, interfaces with Angular, and interactive visualizations with D3.js. The work also involved data collection, database query optimization, and server deployment.
After Japanese language, business, and development training through B-JET, I joined Have a Talk Inc. in Miyazaki. There I developed Laravel and Ruby on Rails applications, implemented multi-factor authentication with WebAuthn and SMS links, and worked on database performance. That experience informs how I approach AI features today: as part of a wider application with authentication, data, and operational requirements.
My current interests are document-grounded AI, agents that connect to application tools, and the engineering needed to support those features in a deployed service. I also explore how coding agents can support everyday software development.
