# Hardik Zinzuvadiya

> ERPNext specialist and AI software engineer. Five years inside Frappe and ERPNext. Certified Frappe Developer and Software Engineer II. I build AI agents that draft inside the ERP, the custom apps around them, and the servers that keep them up.

Site: https://hardikzinzu.com. Contact: hardiktech7@gmail.com. Remote from India.

## What I do
- Servers, hosting and hardening: Two application servers, a primary MariaDB with a replica ready to take over, Docker, CI/CD and Grafana alerting, with hardening as the baseline.
- Version migrations and upgrades: Compatibility audit of your custom apps, a migration rehearsed on a copy of production, data validation and a tested rollback plan.
- Custom Frappe apps and features: Features ERPNext does not have, built as proper Frappe apps that survive upgrades instead of patches to core.
- Integrations and syncs: Shopify, payment gateways, WhatsApp Business, e-invoicing and any REST or GraphQL API, with idempotent syncs and visible error queues.
- AI agents inside the ERP: Assistants that answer from live ERP data and draft records for a person to approve, bounded by permissions and cost ceilings.
- Backend services and APIs: The Python services and servers underneath: background workers, schedulers and push delivery from your own infrastructure.
- Database and query work: MariaDB and PostgreSQL under real volume: slow queries, indexes and background workers, measured before and after.
- Code review and contribution: Contributor to Frappe and ERPNext. AI writes a lot of the first draft here; every line still passes a review, a test and a security check.
