Hi, I'm Jay.

An unknown student of systems, money and the land.

Software engineer. Banker. Now working on rural finance.

Zoom in far enough,
every map is a farm.

I build for that field.

Field notes · 2026

I'm at my best where three things meet: software, banking and rural India. Most of what's on this page is me trying to make those three work together.

The route

Three legs, one direction.

Each job gave me a way of seeing the problem that I didn't have before. I studied geo-informatics, so I tend to think in maps, layers and districts.

2019 — 2021

Code

Systems engineer · a global IT services major

Built GIS and digital-twin systems for electricity utilities in Australia and the UK. Taught me how large systems actually ship.

Credit

Probationary officer · one of India's largest public sector banks

Worked in branch banking with real customers, real loan files and real constraints. Taught me where the money gets stuck.

Countryside

Officer · a national development finance institution

I design and run training for bankers who serve rural India, and I work on data, IT and AI initiatives. I'm trying to answer one question: can technology reach the last branch?

Layer 01 · Builder

I learn by building things.

Reading about a system tells me what it claims. Building one tells me what it costs. These are independent projects I build in my own time.

Layer 02 · Banker

Teaching bankers to go digital.

The kinds of work I do in development finance, described in general terms. No institutional data, documents or positions are shared here.

01

A bank you can practise on

For a two-day programme on digital-native banking for senior bank executives, I built a complete offline demo bank with 11 hands-on tools. Participants run the processes themselves instead of watching slides.

02

Feedback that leads to decisions

I combined feedback from dozens of training programmes, more than a thousand responses, into one live dashboard. Patterns that used to sit in folders are now visible at a glance.

03

Mission control for programmes

A tracker that follows hundreds of programmes through every stage from plan to completion report, plus an automated morning brief so nothing slips.

04

District-level credit data

I extracted and cleaned credit-potential data for every district of a large state, then built data-entry tools so field officers can add to it.

Layer 03 · Researcher

Questions I ask of district data.

I research in panels and maps, using public data: credit, rainfall, night-lights, satellite greenness. These are my own working papers.

Published series
A data series on rural credit and financial inclusion

A recurring data series on rural credit and financial inclusion, published in CAB Calling, a journal for the banking community.

Working paper
Does farm credit follow the monsoon?

Rainfall shocks and agricultural lending across districts.

Working paper
Night-lights and credit: are districts converging?

Satellite night-time light as a proxy for growth, compared with how credit spreads.

Working paper
Fewer borrowers, bigger loans

What happens to inclusion when loan sizes grow faster than the number of accounts.

Working paper
Farm fires and the credit cycle

Stubble burning seen from orbit, alongside farm finance on the ground.

Working paper
Heat, drought and crop greenness

Using vegetation indices to see climate stress before it shows up in loan books.

Working paper
Environmental stress and where people move

Forest, air, climate and water stress compared with population change across districts.

House ruleAssociation, not causation. When the data can't prove something, I say so.

Off the clock, under the sky.

Deserts, hill towns, the coast I grew up near, and the darkest skies I can get to.
