I build custom business apps that replace spreadsheets and manual steps: ERP and CRM systems, quoting platforms, HR and POS tools, and client portals with role-based access. Past builds include a quoting platform for an industrial equipment maker, the N6 ERP, an HRM system and a multi-tenant POS. Stack: React, Django, FastAPI and PostgreSQL on AWS. You get the app, an admin panel and support after launch.
