Hi, I'm George.
I build software. I currently work at JPMorgan as a VP Lead Software Engineer, and in my own time I build with AI. This is where I put my apps, tools and writing.
Tools
- MortgageMonthly payment and total interest for fixed, variable and fixed-then-variable rates
- Rent or buyCompare renting and buying a home over the years you plan to stay
- Total cost of ownershipWhat a car, or anything else you buy, really costs over the years you keep it
- Savings growthHow regular saving grows over time, and what it's worth after inflation
Apps
Writing
- How a mortgage payment is calculatedMoney · the formula, worked through with real numbers
- Never store money as floatsTech · why 0.1 + 0.2 isn't 0.3, and what to do instead
- AI suggestions should wait for your approvalAI · suggest, don't act, in a finance app
- Where every number comes fromMoney · what banking projects taught me about trusting numbers
