More thanjust code.
I enjoy working where engineering meets problem-solving. From architecting full-stack applications to exploring retrieval-augmented generation and leading technology operations, I approach every project with a focus on functionality, scalability, and thoughtful execution.

05AI / Machine Learning
Retrieval-Augmented Generation (RAG) System
A custom RAG pipeline that connects large language models to an external vector database for accurate, traceable and up-to-date answers.
- 01
User query
A question arrives in natural language and is prepared for search.
- 02
Retrieval
The query is matched against an external vector database to find the most relevant passages.
- 03
Context
Retrieved passages are ranked and assembled into focused, up-to-date context.
- 04
LLM
A large language model generates an answer grounded in that context rather than in memory alone.
- 05
Response
The answer comes back traceable to its sources — the step that keeps hallucination in check.

- External Vector Database

06Web Development / Motion Design
The person behind the projects.
I'm Rafsan, a developer and technology leader based in Dhaka. I study Computer Science Engineering at the University of Liberal Arts Bangladesh, with a minor in Business Administration, and I build full-stack products — from healthcare scheduling and learning platforms to campaign, esports and federation websites.
Since 2020 I've also led technology at Zenetic Esports and directed operations at LEVEL 7 Marketing Solutions. Working on both sides — writing the code and running the operations around it — shapes how I build: clear structure, dependable systems, and details that hold up in use. More recently, I've been exploring applied AI — particularly retrieval-augmented generation.
