Building,
learning,
writing.
I'm Gulshan Kumar, a 3rd-year B.Tech Information Technology undergraduate exploring artificial intelligence, software engineering, and emerging technologies through projects, experiments, research, and technical writing.
Questions I'm
following.
Learning, researching, and building in public—one practical thread at a time.
AI agents
Building systems that can reason, use tools, and complete tasks.
RAG and LLM systems
Retrieval, vector search, and production knowledge systems.
Software architecture
Designing reliable systems and understanding their trade-offs.
Research workflows
Turning papers and developer tools into testable implementation notes.
A few things worth
reading.
AI & MLUnderstanding RAG Systems: From Documents to Context-Aware AI
A practical mental model for retrieval-augmented generation, from document chunks to grounded answers.

SoftwareDesigning for Failure in Small Systems
Reliability is not only a distributed-systems concern. Even small applications benefit from making failure paths explicit.

I'm interested in the space where a strong technical idea becomes a useful system. This publication is where I document that process honestly: the models that surprise me, the code that breaks, and the concepts that finally click.
“The archive matters because the journey is part of the work.”
