Software Architecture • AI • Microservices — Built for Production, Not Demos
Hi, I’m Rahul Sahay — a Principal Software Architect with 18+ years of hands-on engineering experience, helping teams and individuals design, build, and scale real-world software systems.
I don’t just teach tools. I help you think like an architect in an AI-first world.
What I Bring to the Table
End-to-End System Design Expertise From Clean Architecture and Low-Level Design to Microservices, Cloud, and AI systems (RAG, LLMs, Copilots) — I focus on why decisions matter, not just how to implement them.
Production-Grade Experience I’ve worked across:
Large-scale enterprise systems
Web & backend services
Distributed, cloud-native architectures Not slideware. Not toy projects. Production realities.
AI + Engineering Judgment I work at the intersection of AI, ML, and software engineering, helping developers use AI as a force multiplier — without outsourcing thinking, design, or responsibility.
Teaching That Engineers Respect
Former Microsoft MVP (7x)
48K+ learners across courses
Speaker & trainer at conferences, code camps, and engineering forums worldwide
I teach the things people usually learn after systems break.
Knowledge Sharing, Done Right
In-depth courses on Clean Architecture, Microservices, Cloud & AI
Practical blogs that cut through hype and buzzwords
Clear explanations for beginners, plus architectural depth for senior engineers
If you care about long-term maintainability, scalability, and correctness, you’ll feel at home here.
Who I Work Best With
Developers who want to level up beyond frameworks Engineers preparing for senior/architect roles Teams building AI-powered systems that must actually scale Anyone tired of “copy-paste architecture” and shallow tutorials
Let’s Build Something That Lasts
If you’re looking for guidance in: ML•AI • RAG • .NET • Microservices • Cloud • Docker • Kubernetes • Angular • System Design
you’re in the right place.
Let’s move beyond hype and build production-first software.
