I work in investment banking, where technical questions are part of the job.

Software became how I investigate those questions, test the assumptions behind them, and build better answers.

From investment banking to public software work

Investment banking

This is where the questions begin: decisions under constraints, dense information, and assumptions that must stay clear.

Start with the decision.

Technical pressure

Recurring friction showed me that a process is hard to improve when it is hard to inspect.

Make the problem legible.

Software development

Software became the method: make assumptions visible, test ideas, and build a better answer.

Build a working answer.

Public work

I share the methods, trade-offs, and questions behind the work for technical and financial readers.

Share what stays useful.

Questions in. Working answers out.

What I’m building now.

Finance gives me the context: decisions under constraints, dense information, and the need to make assumptions clear. Recurring technical challenges kept exposing the same problem—when a process is hard to inspect, it is hard to improve.

What began as a way to examine a problem became a way to build a better answer. Code lets me test ideas and turn complex financial information into tools people can use.

Outside work, I follow fintech products and market changes, read about how people interact with money, and keep building projects of my own.

Savyy is the clearest example: a personal-finance product that brings scattered financial information into one inspectable view. It reflects the standard I care about most—complex systems should explain themselves.

Bring me a question worth testing.

This site is where I share that work and write about the questions behind it. If you are working on a financial product, a technical problem, or something between the two, get in touch.
