03 / THE PERSON BEHIND THE CODE

Serious about the work.
Curious about everything.

I’m Shivji, a Data Scientist I at Merck Group. I turn interesting ideas into intelligent systems people actually use.

Before moving into my current role in September 2026, I spent 1 year and 5 months as a Full Stack Developer (AI) at Merck. My work spans agents, language models, search, and data infrastructure, with a focus on making complex things useful and reliable.

Outside the production pipeline, I make things just to see what’s possible. Like the browser games a little further down this page.

The thinking behind
the systems.

A few big ideas, made a little more tangible.
Follow the flow. Explore what makes them work.

RETRIEVAL-AUGMENTED GENERATIONCONCEPT MAP / 01

Good answers start with
the right context.

Documents become searchable chunks. A question retrieves relevant passages, then an LLM uses that context to compose an answer with sources.

THE ENGINEERING DETAIL

Retrieval quality matters as much as generation. Check relevance, preserve citations, and allow an honest “I don't know.”
