Application Engine: Schema-Driven Backend
We got tired of writing CRUD for every new entity. So we built a system where you define an entity in JSON and get the API endpoints, UI metadata, workflows, RBAC, ABAC, role-based permissions, and real-time events automatically. This is the backbone that powers every THB CRM deployment.
System Architecture
JSON schema in, fully operational multi-tenant API out. Workflow automation, omnichannel messaging, background processing, and preset-driven deployments -- all generated from the schema definition.
Core Capabilities
Everything a healthcare CRM backend needs. Defined in configuration. Enforced at runtime. Scaled in production across 150+ hospitals.
Schema-Driven Everything
Define an entity once. The engine generates API endpoints, validation rules, UI configurations, view layouts, and workflow state machines automatically. Add a field, everything updates. No migrations, no downtime.
Preset System
Deploy entire CRM verticals from configuration. Patient CRM, Doctor CRM, B2B CRM, Sales CRM -- each preset includes entity schemas, workflows, views, notification templates, and sample data. New vertical in hours, not months.
Multi-Tenancy
Each hospital gets complete data isolation at the infrastructure level. Cross-tenant data access is architecturally impossible -- not just policy-enforced. Every request carries tenant context through the entire stack.
RBAC, ABAC & Row-Level Security
Role-based and attribute-based access control enforced at every API call. Row-level security policies ensure users only see the records they are authorized to access. Permissions defined in configuration, not hardcoded.
Workflow Automation
Entity lifecycle managed through configurable state machines. Each transition can trigger notifications, update related records, call external systems, and route tasks -- with full transactional guarantees and audit trails.
Real-Time Events
Every entity change is streamed to connected clients instantly. Per-tenant and per-user event routing ensures the right people see the right updates. The CRM frontend stays in sync without polling.
Omnichannel Messaging
WhatsApp, Facebook, Instagram, Teams, Telegram, Discord, Slack -- all built in with production-grade adapters. Multi-tenant routing automatically resolves which hospital handles each inbound message.
Integration Layer
Third-party connections via OAuth, configurable webhooks with retry policies, and hospital system connectors for patient identity resolution. Connect to any external system your hospital already uses.
Background Processing
Async workers handle batch operations, event subscriptions, data ingestion, integration sync, notification delivery, and scheduled jobs. The API stays responsive because heavy lifting happens in the background.
Enterprise Query Engine
Production-grade query capabilities through a REST API: deterministic pagination, multi-entity joins, aggregate queries, field-level selection, and row-level locking for concurrent operations.
Dynamic View Configurations
Schema-defined view types: list views with sortable columns, kanban boards with configurable lanes, and calendar views with date-field mapping. The frontend renders whatever the configuration declares.
Hybrid Search
Keyword and vector search combined across all entity fields. Automatic index sync on every write. Typo-tolerant, faceted results that surface the right records instantly.
Define Once, Generate Everything
One entity definition. No migrations. No boilerplate. No separate UI config. No workflow definitions file. Everything comes from the schema.
Full CRUD with validation, filtering, pagination, and joins -- all auto-generated from the entity definition.
RBAC and ABAC policies, row-level security, and column-level encryption -- defined in the schema, enforced at runtime.
List, kanban, and calendar view configurations sent to the CRM frontend. The UI adapts to whatever the schema declares.
State transitions with automated notifications, record updates, and external system calls -- all triggered by entity lifecycle events.
The result: A new entity -- with full API, access control, views, workflows, and search -- goes live in minutes. No code written, no deployment needed, no migration to run. This is how we ship new CRM capabilities across 150+ hospitals simultaneously.
Workflow Automation
Every entity has a lifecycle. Appointment booked, confirmed, completed, cancelled -- each transition can trigger notifications, update records, and call external systems. All configurable, all audited.
What Workflows Can Do
Each state transition triggers a configurable sequence of actions -- all within transactional guarantees.
Enterprise Guarantees
Healthcare workflows cannot afford partial state changes or lost notifications.
Multi-Tenancy & Security
Hospital A cannot see Hospital B's data. Not because of a filter -- because they are isolated at the infrastructure level. Role-level security and access-level permissions are enterprise requirements, not optional features.
Tenant Isolation
Infrastructure-level
Every hospital gets complete data isolation at the infrastructure level. Cross-tenant access is architecturally impossible -- not just policy-enforced.
RBAC, ABAC & Row-Level Security
Every API call
Role-based and attribute-based access control enforced at every API call. Row-level security policies ensure users only see the records they are authorized to access. Permissions are defined in configuration, not hardcoded.
Compliance-Ready
Audit-ready
PII encryption at rest and in transit. Full audit logging of every data access and mutation. Activity tracking across every user action. Deployable on any major cloud with compliance controls.
