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.
