Practical guides on ABDM integration, multi-tenant SaaS, DPDP/GDPR compliance and applied AI — field notes, design patterns, and engineering tradeoffs from 15+ years of designing clinical healthcare networks, multi-tenant databases, and deterministic software.
How to engineer clinical workflows that survive intermittent power, high-latency 4G fallback, conflict-free sync, and strict transactional data integrity at public hospital counters.
A developer-first breakdown of Ayushman Bharat Digital Mission architecture: ABHA verification, HIP/HIU gateway patterns, FHIR JSON diagnostic bundles, and cryptographic consent artifacts.
Comparing schema-per-tenant, database-per-tenant, and shared-schema Row-Level Security (RLS) in production PostgreSQL. Connection pooling, migration ergonomics, and noisy-neighbor isolation.
Applying immutable double-entry financial ledger accounting to biological pharmaceuticals (Anti-Hemophilic Factor). Eliminating phantom stock, tracking batch lot expiries, and securing inter-hospital transfers.
Why raw prompt engineering fails on unstructured invoices and clinical discharge summaries. Combining schema-constrained generation (JSON Schema / Zod), citation anchoring, and deterministic validators.
