The Workshop
Product thinking, platforms and AI, and the things I build to test them: a home lab, self-hosted tools, and the occasional experiment that didn't work.
Digital Christin, In Progress.
Engineer, Founder, Product Leader. Also Lego, F1, and more books than shelves can hold.
The Library
Books, sci-fi and fantasy, films and TV, with ratings. Mostly things I'd hand you, a few I'd warn you off, and far too much about The Expanse.
The Collection
Collectibles, Lego, and books kept as objects rather than just read. The same pieces show up on my YouTube and Instagram.

Price rules and affiliate note
A Must Buy is at least a quarter under the price a set usually sells at; Fair Price is 15% or more under it. Many sets already sell well below MRP, so a big percentage off MRP is often just the normal price.

Movement
- pageRunlog
Every run gets a replay. Slow kilometres and walk breaks are left in.
The Music
What I listen to and why it stuck, from the songs that found me in a small Kerala town to whatever's on repeat now.
The Pit Wall
F1, Hamilton, and driving for the love of it.
The Road
Places I've been and how I got there: treks, road trips, and the detours that turned out to be the point.
Everything, newest first
I Used to Wait at the Finish Line
After years of driving my wife to her races and waiting at the finish, I lost 22 kilograms and started running with her.
Nobody Asks the Kid
Children made to hug, kiss and share on demand learn that their no does not count, and one father showed me what letting them decide looks like.
We Asked Our Guide What He Used to Poach
Two days on the Periyar Tiger Trail in Thekkady with an ex-poacher guide: leeches, hornbills, gaur herds, a forest camp and no tigers.
Worth Every Piece
A review of the LEGO Technic Ferrari SF-24 (42207), built with my wife, rolled down a road and run on a treadmill.
Where We Camped Is a Road Now
Camping and stargazing at Gandikota Fort in February 2017, the weekend the whole district came for the festival, and what one year changed.
I Bought the Car Before Getting the Licence
How I failed to learn to drive three times, bought a Polo GT anyway, and have since put 1.6 lakh kilometres on two Volkswagens.
Who Cares, She's a Cat
Six cats in thirteen years, from two abandoned kittens in Cochin to the one who is left.
India is one of the best places to buy LEGO, if you wait for the sale
On an ordinary day India is about level with the US for LEGO. In a sale its best price beats the US shelf price on 78 of 84 sets I compared, and even a 30%-off sale in the UK on 67% of them.
The Steps Nobody Built
The stone steps from my family home in Erumely down to the Manimala River have no known builder, and the ghost stories grew in that gap.
Dumbledore Should Have Been the Villain
Part two of my Harry Potter series, on the adults who fail the children in their care and why Dumbledore works better as the villain.
I Replaced the Heart With a Library Stamp
How the like button on my Ghost theme became a red SEEN stamp that readers can sign, running on a Cloudflare Worker and a D1 database.
Asking Is Cheap
How I ask opinionated product managers to test their ideas with customers before arguing for them, and how interviews became part of judging a release.
I Over-Engineered the Sticky Note
I turned comments off on my Ghost blog and built a 200-character sticky note in their place, with no brief and nobody to stop me.
I Wanted to Retire at 40
I dug up the blog I started in 2009 and checked its first post, a list of worries, against where each one stands seventeen years later.
Nobody Was Building for AI
Why AI-first usually means data-first, told through a news CMS, a B2B sales database and an automotive publisher.
I Put My Bookshelves on the Internet
I photographed three bookcases, had Claude read 535 spines, and rebuilt them as a library page where visitors can rearrange my books.
97 to 83.9, One Morning at a Time
Part two of my weight-loss log: daily weigh-ins from March to July, a US holiday, and a week the scale refused to move.
Tolkien's Saddest Scene Has No Villain in It
How the scene Tolkien called his most tragic taught me to read for people, and led me from The Lord of the Rings to Malazan and Stormlight.
The Two Kids I Finished Harry Potter For
Why I read all seven Harry Potter books after losing faith by the fourth, and why I still read fanfiction about Harry and Hermione.
Sonny Hayes Would Never Pass the Medical
A Formula 1 fan's review of F1 the movie, whose hero would fail an FIA medical on day one and whose young Black driver deserved far better.
The Physics of Coffee Brewing
I grew up on coffee boiled in a pan. Then I watched Hiran treat an AeroPress like an engineering experiment.
From less than 2,900 Steps a Day to 20,000
February: 81,744 steps in the whole month. April: 339,601. In between, a walk after every meal, a friend named Anusha, and no willpower worth reporting.
What Story Points Were Hired To Do
In 2022 I coached my team into story points with LEGO. AI has changed what makes software expensive, and I'd now lead teams out of them, carefully.
Breaking the Habit
B2B users live inside our decisions. Seven years after a newsroom roadshow, this is how I weigh a product change against what it asks people to relearn.
The Dungeon Has a Look Now
A personal site should look personal. Every post here is now a tilted index card, and the light switch is a lightsaber.
