Architecture Notes & Deep Dives

In high-throughput retail environments with fluctuating connectivity, client-side point-of-sale software cannot afford network blocking or floating-point rounding errors. This architectural deep dive examines how 64-bit integer paisa math, Room SQLite WAL transactions, and an idempotent sync outbox state machine guarantee zero data loss and sub-second checkout speeds.

Autonomous multi-agent swarms sound magical until Agent A refactors a function, Agent B reverts it because of missing types, and they burn through $50 in API tokens arguing with each other. Here is how we engineered GH-Swarm using strict state machines, verification gates, and AST diff validation.

When building the Pharma Compliance Engine for hospital pharmacies, an audit failure is not a mild inconvenience: it carries legal liability and patient safety risks. Here is how we designed append-only ledger tables, bi-temporal tracking, and row-level security in PostgreSQL that survive regulatory inspection.
