ROMHARSHAN ARCHITECTURE LAB

Reference architectures grounded in real engineering problems.

Privacy-safe case studies and reference designs covering system boundaries, data flow, resilience, deployment, observability and failure recovery.

Case Study

AI Yard Management Reference Architecture

A privacy-safe architecture study derived from real yard-management work: event ingestion, vehicle state, geospatial persistence, reconciliation, monitoring and failure recovery.

NestJS • Kafka • PostGIS • Computer Vision • Kubernetes

Reference Design

High-Volume Kafka Event Processing

Backpressure, bounded concurrency, retries, idempotency, audit history, dead-letter handling and dependency protection for high-throughput consumers.

Kafka • NestJS • MongoDB/MySQL • Observability

Case Study

Enterprise Booking Platform Blueprint

Search, pricing, booking, payment, webhook reliability and third-party integration patterns for a multi-domain travel platform.

Spring Boot • NestJS • React/Angular • Kafka • Redis

Reference Design

Production RAG Platform

Document ingestion, retrieval, citations, access controls, PII considerations, evaluation and secure tool/function integration.

Python • FastAPI • LangChain • FAISS/Qdrant • Redis

How I structure an architecture review

Business problem, constraints and measurable non-functional requirements
Service boundaries, APIs, events and ownership
Persistence, caching, consistency and data lifecycle
Security, authentication, authorization and secrets
Backpressure, retries, idempotency, circuit breakers and recovery
Deployment, Kubernetes, monitoring, logging and incident response
Cost, team capability, operational complexity and rejected alternatives
