A week ago, my club flag travelled with me from Bengaluru to the United States. This is an open letter to my Rotary family in America - about flags, friendships, and the ideas that emerge when Rotarians from different worlds sit down together.
The complete story of designing a licensing and backup encryption system for a product shipped to customer sites. Ed25519 digital signatures, dual-envelope AES-256-GCM encryption, SHA-256 key derivation, and the master key trust trade-off.
A few days ago, I was inducted into Rotary once again. For many, that may seem like the start of a new journey. For me, it feels more like coming home.
Filesystem encryption, database TDE, column-level encryption, S3 server-side vs client-side - what each layer actually protects, the gaps between them, and how to choose. Drawn from real customer conversations.
A practitioner’s walkthrough of encryption fundamentals - symmetric, asymmetric, hashing - with real algorithm comparisons, a decision framework, and common mistakes from two decades of building production systems.
For years, we built the factory. Pipelines, platforms, guardrails. Then something dangerous happened - the DevOps team decided to build a product of its own.
Most enterprises are buying the F-35s of software - full-scale platforms engineered for extreme scenarios they will never face. The future belongs to composable, modular architectures. A perspective on capability thinking vs platform thinking.
How a monolithic prompt file evolved into a production AI Development Operating System. Real architecture for multi-agent software development: MCP standards, orchestration patterns, and the phases that actually matter.
BitLocker encryption didn’t fail—trust boundaries shifted. When recovery keys are escrowed by default, control becomes conditional. Linux LUKS, VeraCrypt alternatives, and key management strategies for conscious trust decisions.
When geopolitics enters the infrastructure layer, convenience without control becomes fragile. Real incidents, technical alternatives, and why sovereignty requires deliberate architecture.
