Problem

Angola's informal micro-businesses are shut out of the credit system because banks cannot measure their risk — there is no sales history, no bookkeeping, no formal trail.

Solution

a free financial-management backend for micro entrepreneurs that turns day-to-day sales and expense entries into a structured history usable as a basis for risk assessment. My role: design and implementation of the NestJS-on-Fastify backend with Prisma and PostgreSQL — financial domain modelling, authentication, a documented REST API, and tests.

Results

a personal project, developed in the open on GitHub.

Tech stack

NestJS, Fastify, Prisma, PostgreSQL, TypeScript.
