Flagship products
G-HIMS and GC-ERP are Gotham Coders products. Custom enterprise systems are the solutions layer built from the same architecture-first engineering discipline.
Connected finance, procurement, inventory and manufacturing workflows built around the way your business actually operates.
Explore ERPClinical, financial and operational hospital workflows with offline resilience, traceability and role-aware controls.
Explore HIMSCustom enterprise platforms for organizations whose workflows, authority models, or operating constraints do not fit generic software.

Enterprise engineering
The harder work is protecting authority boundaries, keeping data consistent, recovering from failure and making system behavior explainable.
Command-to-Ledger Trust Pipeline
Business events connect operational domains without hiding the history of how state changed.
Permissions, approvals and material state changes are designed to remain attributable and explainable.
Tenant boundaries and role-aware access are treated as architecture, not as a UI convention.
Critical records are validated server-side and designed around durable, recoverable workflows.

Read ERP architecture studyProduct experience
Our public demos are intentionally transparent simulations. They show how we structure operational state, commands and audit history without pretending a marketing sandbox is a production deployment.
Role-aware views
Different teams need different operational surfaces.
Traceable state changes
Actions should remain attributable after the dashboard changes.
Cross-domain workflows
Operational and financial consequences should stay connected.
