When the solution doesn’t exist, I build it.

A finance professional with five years inside hedge-fund operations at Northern Trust. Now I turn everyday problems into polished, private apps — five of them live on the App Store.

01  Ideology

I came across a problem. No proper solution existed. Complaining was an option. Building was a better one.

01

Notice

Every app I’ve built began as friction I lived with — a loan I wanted to understand, a text I wanted to read in peace.

02

Question

I look for the existing answer first. Usually it’s cluttered, ad-ridden, or quietly selling your data.

03

Build

So I build the version I wanted: clear numbers, clean design, no ads, nothing collected.

A note on code

I’m not a software engineer, and I don’t pretend to be. I’m a finance professional who works with AI the way a director works with a crew — I set the brief, own the logic, audit every number, and refuse to ship until it’s right. Writing code is the easy part. Knowing what’s worth building, and when it’s truly finished, is not.

02  Work

Built. Shipped. Live.

Five apps on the App Store, for iPhone and iPhone Duo. Each one started as a problem I had myself.

No. 01

LoanLens

Finance  ·  Free  ·  No ads

Every EMI calculator I found came wrapped in ads and loan offers. LoanLens just does the maths — instant EMI, principal-versus-interest charts, a full amortisation schedule and prepayment scenarios. Nothing leaves your phone.

No. 02

The Bhagavad Gita

Education  ·  Free  ·  No ads

All 701 shlokas across 18 chapters — Sanskrit, with Hindi and English translations. Fully offline, no subscriptions, a verse of the day on your Home Screen. Scripture shouldn’t come with pop-ups.

The Bhagavad Gita screen: home, with continue reading and chapters
No. 03

Runrate

Utilities  ·  One-time purchase  ·  No ads

What does your vehicle actually cost per kilometre? Log a stop in fifteen seconds — fuel or EV — then watch the trend, compare vehicles, and get told when efficiency drifts.

View on the App Store
Runrate screen: running cost per mile, above this month’s spend by vehicle
No. 04

RosterRhythm

Health  ·  Free trial  ·  No ads

Sleep advice assumes you sleep at night. Shift workers don’t. RosterRhythm turns a roster into a daily plan — sleep window, wake time, caffeine cut-off and nap timing.

View on the App Store
RosterRhythm screen: Today, with the next step in a shift worker’s plan
No. 05

Dawnwick

Utilities  ·  One-time purchase  ·  No ads

An alarm clock tells you when you’ll wake up. Dawnwick shows how much night is left — a live countdown, a line that burns down over eight hours, and one swipe to skip tomorrow’s alarm for a holiday.
