Recorded run, free lab: Tatkal seat concurrencyRun it yourself →
PHASE 1: The Production Trap - Read, Decide In Code, Then Write
25 workers read Seat #1, think for 300 ms, then update. No lock.
Reported 'SUCCESS'   : 25
Reported 'SEAT_TAKEN': 0
Row says held_by     : user_10 (last writer wins)
>> DISASTER: 25 users were told they got Seat #1. No error was raised by the database.

That is a recorded run of a free lab. The same script runs on your laptop and checks every result itself.

Real Artefacts

Look Inside

No hypothetical hand-waving. Here is the actual level of depth in the lessons, the Docker lab test runners, and the architectural diagrams.

Lesson SnippetFrom the free first lesson

What System Design Actually Is

"The architect is not the person who knows the fanciest venue or the rarest database. The architect is the person who makes the right call for the current constraints, and can clearly explain what they gave up."

[TRADEOFF] Every optimization has a victim: latency vs durability, consistency vs availability.
Lab VerificationRecorded run, excerpt

Lab 00: Container Assertions

== Step 1: is Docker alive?

[OK] Docker answered

== Step 3: run a container from it, with a port

[OK] container answers on http://127.0.0.1:18110

== Step 5: break it. Same port twice

[OK] second container refused: the port is already taken

== Step 7: fix it with a volume

[OK] with a volume: counter continued from 3 to 4 after docker rm

About Me

From a Non-CS Background
to Software Architect

I didn't come from a CS background. I figured things out the hard way, failed a bunch, and eventually found my footing. Somewhere along the way, 12 years passed and I'd gone from writing my first loops to architecting systems that millions of people use.

I've worked with some large clients, including in the enterprise and SaaS space, leading teams building distributed systems, AI-powered products, and backend infrastructure that actually holds up under load. The scale taught me a lot. So did the outages.

The Desi Architect is my way of sharing that experience without the fluff. Real system design, real tradeoffs, for developers who are serious about growing.

What I Offer

How I Can Help You Grow

Most people I work with are prepping for system design interviews, building an AI product, or trying to scale something they already shipped. That's where I help.

What People Are Saying

Real feedback from mentees and the YouTube community.

"One of the most valuable career conversations I've had. He didn't give me a generic roadmap. He listened, understood my exact situation, and gave me a clear, practical direction I could act on immediately. The focus on fundamentals first, and knowing WHEN to use something rather than just HOW, completely shifted my thinking."
