I turn a real problem into a product people use every day, then keep it running.
My work starts at a real counter: a club that needs exact billing, a café that needs orders to reach the kitchen, a shop with no signal. I design the data model, write the backend, build the interface and the Android app, connect payments, and deploy on infrastructure cheap enough for a small business to keep.
I work with AI coding agents inside strict guardrails: every change passes type-checks and tests before it ships, money is handled as integers, and anything touching payments or authentication gets a security review.
