Sandhya
S.

APIM Engineer. Analytics Grad. Published Researcher.

I spent the better part of two years automating the infrastructure that makes global operations run — then decided to understand the business behind it. B.Tech CSE from VIT. PGDM at Great Lakes. Currently an Analyst Intern at BNY.

The Thesis
Tech without
business sense.
Business without
tech fluency.
Both are broken.

I have watched this happen from both sides of the table. Engineers ship features that miss the business problem entirely. Strategy teams propose roadmaps that are technically incoherent. The gap between them is not a communication problem — it is a fluency problem.

I have spent months building deep fluency on the engineering side — architecting APIs across global enterprise operations, automating at scale, owning outcomes. Now I am building the same fluency in business, analytics, and strategy. Not to pick a side. To be the person who does not have to.

The bridge between both worlds — that is the entire point.
About

Engineer at core.
Strategist by design.

I am a 24-year-old engineer who got tired of seeing only one side of the equation. At Schneider Electric, I built and automated API infrastructure consumed by Sales, Marketing, Operations, HR, Banking and B2C users across the globe — 70+ interfaces, 3.3B+ annual transactions, zero-downtime migration of 365 APIs.

That work earned me the ExcellenSE Mountain Mover Award and a Step-Up Recognition. It also made clear that the most interesting problems live at the intersection of technology and business strategy — not inside either one alone.

Now I am at Great Lakes Institute of Management, Chennai with a focus on analytics, and currently interning at BNY. Co-authored research published in Elsevier with 65+ citations. Competed in national hackfests. The pivot is deliberate — this is the honest, unembellished version of that story.
