In production

Modular ERP monorepo

A modular ERP running in production for enterprise clients. I own the monorepo: I build and maintain the modules in React, TypeScript and Node.js on Microsoft SQL Server, I designed the data models for the client-facing modules, and I standardised development and deployment with Docker.

Chosen architecture

Financial BPO platform

I define the platform's frontend architecture. I selected TanStack Start, with TanStack Query handling server state, caching, and loading and error states — over a client-state library, because the product is API-driven. I also contribute to the Node.js backend, inside a monorepo that houses the product's proprietary AI layer. This site runs on the same choice.
