Scouting report

Accountant-turned-junior dev building fintech apps in Python, FastAPI and React Native

assessed from open-source footprint

Mid
45signal

Jesus is a self-described junior full-stack developer pivoting from a 10-year finance career, which shows in his fintech focus: a functional trading app and a React Native bank app among 15 original repos. His stack spans Python/FastAPI, React/React Native and an interest in LLMs. Consistency is high but impact is near zero (no stars, one follower, no authorship signal), so this is an early-stage but genuine and domain-motivated portfolio rather than a proven track record.
