Production Systems
- Frappe Framework
- ERPNext
- Python
- MariaDB
- Redis
- Backend APIs
- Business workflows
- Database-driven applications
- Production debugging
- Git-based development
Learning to build software where reliability, maintainability and business logic matter more than just making a feature work.
I'm particularly interested in building AI systems that are integrated into real products, rather than isolated demos.
