YASH SINGH · INFORMATION SYSTEMS

I make business systems
make sense.

I study how people, data, and technology work together inside organizations — then design systems that help people make better decisions.

FEATURED CASE STUDY

Operating a real business

At Floral Station Deli, the problem was not a lack of software. It was that orders, inventory, vendors, scheduling, and online sales all lived in different places.

I designed and implemented an e-commerce website, point-of-sale integration, and Excel-based inventory automation while managing daily operations and a six-person team. My résumé reports a 32% increase in sales and an 18% reduction in waste.

Figure 1. Sales indexed to a baseline of 100, illustrating the 32% increase reported in my résumé. The prototype below uses sample records, not business data.
01 / OBSERVE

Map the actual workflow

Follow an order from customer entry through preparation, payment, fulfillment, and reporting.

02 / CONNECT

Remove duplicate work

Bring online and in-store demand into one operating view instead of parallel processes.

03 / MEASURE

Expose decisions

Turn sales and stock data into practical signals: prepare, reorder, or investigate.

THREE WORKING PROTOTYPES

Systems lab

Explore order operations, relational data modeling, and incident response. The full order app saves demo records on the server; the embedded examples below use temporary sample data.

SYSTEMS ANALYSIS

How I think

A good system is not the one with the most features.

It is the one that gives the right person the right information, removes a needless step, and makes the next decision obvious.
