Tools I developed and use

I wanted to learn front end to be able to build tools that everyone can use instead of running scripts on their machine. Although scripts are still useful, I felt that certain tasks are easier with a user interface, especially for non technical users.

Standard Chartered Monthly Average Balance Calculator

HTML, CSS, Javascript, React

Upload your SCB account statement CSV file to automatically calculate monthly average balances with detailed daily breakdown. Current month appears first, followed by previous months.

UOB KrisFlyer Debit Card Calculator

HTML, CSS, Javascript, React, Tailwind CSS

Calculate the Monthly Average Balance (MAB) required to maximize your miles based on your spending.

UOB KrisFlyer Debit Card Transaction Parser

HTML, CSS, Javascript, React, Tailwind CSS

Parse your UOB KrisFlyer Debit Card transaction history to calculate the Monthly Average Balance (MAB) required to maximize your miles based on your spending.

Miles Visualizer

HTML, CSS, Javascript, React, Tailwind CSS

Punch in a purchase amount and see which UOB and DBS Woman’s cards earn the most miles, including a split across cards when that beats a single swipe.

DBS Woman’s Card Spend Tracker

HTML, CSS, Javascript, React, Tailwind CSS

Drop in a DBS card transaction CSV to track calendar-month spend against the S$1,000 Woman’s Card cap. Counts by transaction date, including pending, less refunds, and ignores payments.

UOB Monthly Average Balance Calculator

HTML, CSS, Javascript, React, Tailwind CSS

UOB’s export stops at 100 rows, so the statement file can’t rebuild the month. Enter UOB One, UOB Lady’s Savings, and UOB KrisFlyer, name each card, and see how much KrisFlyer spend still earns 6.4 miles per dollar.
