Engineering Log & Architecture
In-depth architectural post-mortems, systems design patterns, and engineering notes from production systems. Written by Nikhil Anand on local-first desktop apps, enterprise AI, and high-throughput web architectures.
How we engineered a high-converting direct-ordering PWA for Sassy Tandoor with Next.js App Router, edge caching, and automated WhatsApp Cloud API dispatch, slashing 30% aggregator commission leakage.
How we engineered a zero-latency, local-first retail point-of-sale engine for high-volume tractor spare parts counters that runs 100% offline using Tauri v2, asynchronous Rust, and WAL-mode SQLite.
Architectural breakdown of an enterprise retrieval-augmented generation pipeline built at Aretove Technologies, achieving 90%+ semantic accuracy across 10,000+ proprietary regulatory documents using LangChain, ChromaDB, and FastAPI.
