Subham Bhattacharjee
Founder, builder · Bangalore, India
I build software products and run the companies behind them. Right now that means Loominote, and my studio BinaryVlue.
Before this I spent ten years as a solution architect and consultant for product companies in Berlin, the US and India. Lately I have mostly been learning the parts I used to leave to other people: marketing, content, distribution, talking to customers. Turns out that is most of the job.
Coffee, consulting, or just saying hello.

Two things I'm working on
One product I'm building, and a limited amount of outside work. If either is relevant to you, get in touch.
Loominote for enterprise teams
Loominote is meeting intelligence, not just a note taker. It records, transcribes and summarizes, pulls the action items out, and briefs you before the next conversation. I am building the version enterprise teams need, and I would rather build it with a few of them than guess at what they want.
- Record anywhere, on iPhone, Apple Watch, or the LumiPin, including out in the field
- Every call comes back summarized, with the action items already separated out
- Syncs into the tools the work lives in: your CRM, Jira, Linear
- Walks into the next meeting having prepared you for it
Thirty minutes. Bring the skeptical people.
Consulting and forward deployed work
I take on a small amount of outside work through BinaryVlue. Usually that is sitting close to a customer, getting something complicated into production, and leaving the team able to run it without me.
- Mobile and web app development, from nothing to shipped
- Forward deployed engineering and solution architecture
- Platform migrations, frontend architecture, performance
- SOC 2, HIPAA and ISO 27001 readiness, for the teams who need it before a customer will sign
- Remote, across CET, EST, Singapore, Australia and Japan
No deck needed. Just tell me the problem.

Projects
What I'm building
A studio, the products I'm putting my own time into, and the side projects I build to understand something properly.
Zucini
Deliciously healthy
AI curated meals built around your mood, your goals and whatever is already in your kitchen. Curated by AI, backed by dietitians, chef crafted. Published it under BinaryVlue, shipped it to the App Store, and sold it in December 2025 to a buyer I cannot name.

Web analytics
No cookies.No creep.
Lightweight, privacy first analytics.
Cutelytics
Privacy friendly web analytics
A lightweight, cookieless alternative to Google Analytics. Small script, no personal data, numbers you could actually read. It did not find enough users and I shut it down, but I would build it again.

Speaking
Talks
Mostly about making React fast, and the trade offs nobody puts on the slide.
Supercharging React Performance with JavaScript Signal Optimisation
How signals change the mental model for React rendering, and where they earn you real performance rather than just a smaller re render count.
Setup
What I use every day
The desk, the machine, the camera, the car. Everything here is something I actually own and use.
Setup
~/desk
Herman Miller Aeron
The one piece of gear I stopped thinking about the day it arrived.
Apple Studio Display XDR
The 2026 one. Mini LED, 120Hz, and one cable to the Mac. The single biggest jump this desk has had.
MacBook Pro M1, 2021
Five years on and it still has not given me a reason to replace it.
Shure MV7+
USB and XLR, with the denoiser doing quiet work on the room. Calls, recording, and sounding like a person rather than a laptop.
Audio-Technica ATH-M50x
The pair everyone owns, for good reason. Nothing clever, just right every time.
Sony WH-1000XM5
What goes in the bag. The noise cancelling is the difference between working on a flight and not.
Sony ZV-E10
Webcam duty most days, actual camera the rest of the time.
iPhone 17 Pro
Daily driver, and where most of the desk photos come from.
Tudor Black Bay 58
The one that gets worn most. Right size, no fuss.
BMW M340i
The daily driver. Straight six, and no speed chime, because I wrote up how to remove it.
Some links here are affiliate links. If you buy through one I may earn a small commission, at no extra cost to you. I only list things I actually use.
