Our pedigree?
Either BITS, an IIT, or an IIM. It was just inevitable.
We have learnt this though, over 3 years of building Latency Donuts.
Curiosity matters. Passion matters. Hunger matters.
Schooling and gpa do not.

Why are we called LD?
12 years of presenting latencies as donut charts will do that to you.
We now think eat sleep and visualize in terms of donuts.
Sometimes. We also drop in unannounced at your place of work with free donuts.
Only if you become a client

We'll do it for free.
Our development philosophy?
We charge for a Mercedes Benz because we give you a Mercedes Benz. Stable, reliable, scalable code, that is performant, elegant, and always works
SSH over PuTTY. CLI over GUI.
We dig deep, think, design, code & write from first principles,
avoid integrations.
Our own code, from the ground up.
Here's a smattering of technologies we've leveraged, things we've built for past projects
- HTML, CSS, Javascript

- Typescript, Bootstrap
- NodeJS
- PHP
- Websockets
- Server sent events, long polling
- SQL
- APIs

Steganography 101
We hid 100,000 characters from The Great Gatsby and a discount code into the pixel data for the image below.
Want to distract yourself from that midlife existential crisis?
Try clicking on the images below. Convince yourself both images are visually undifferentiated.
Then, click anywhere outside the section below to flip this card.

2022 March
First winner found. Receives a 12% discount. We are mortified it was so easy.
2022 August
2nd winner of the more convoluted steganography process found. Receives 20% off
2023 Mar
Marketing decides to up prize money to quarter of project value, no limits.
2025 Feb
First winner of new discount found. Discount awarded
2025 June
Second winner of new discount found. Discount awarded
Your mission, should you choose to accept it:
- Click below to download the edited image.
- Load the pixel data for the image with python to play around with it and discover the discount code.
- Flatten the image and store it in a numpy array for fast pixel level ops.
- Adjust for transparency, and try playing around with different encoding standards and steg techniques to discover the message.
- Standardized tools like steghide etc wont help because we wrote a custom encoder for this.
Update - March '24:
We got carried away.
Its now slightly more difficult to find our discount code. So its not really Steg 101 any more.
As compensation, if you succeed, we will do your project for quarter off.
We guess we will do 5 such projects in toto.
What a selected panoply of our clients say about us
These guys love solving problems. We run some very old software for which OEM and vendor support has run out twice in the past, both times for critical services.
One was an outage for a gas recharge system, and the other for a building access control system. Both were diagnosed by this team, with zero support from the original vendors, with zero access to the system documentation. Working with them was painless. They did all the heavy lifting, pretty ran everything on autopilot, used me to unblock the system and processes when needed.
I love waking up to a simple "Sorted, BVS" in the morning from them.

We're a shipping spare parts B2B retailer. Responding to leads used to take several hours, but LD brought this down to a second. I can receive whatever reports I want on my email, in telegram, on demand and regularly.

Not many come on as consultants, say no to our CEO, and survive. They did.
I like that I can pick up the phone and have a casual chat about tech and they understand where I am coming from, the bigger picture. They understand how tech works in tandem with strategy, marketing, analytics and product, which has made it easier for us to build better services.
They think in terms of cost, performance, compute, reliability etc, instead of trends and the latest flashy tech to come out of Silicon Valley.

We had a very slow site hosted on a major nocode platform, which couldnt handle the sudden spikes in demand from our promotions on Cred and Amazon.
LD shifted us to GCP servers, hardened them, optimized our backend code, brought down the front end package size by 58%, implemented analytics for us. We absolutely adore them.

I like working with them because I can bring LD's team into the board room with me. We work out detailed numbers, analyses and charts with them before I walk into my quarterly review, and I take one of their analysts along.

We went through three vendors before we chanced upon Latency Donuts. They were able to build an image processing pipeline for us that digitized 30,000 patient prescriptions, without needing manual intervention.
Their code detected our paper prescriptions, deskewed, desaturated, cropped, allowing us to generate clinical grade digital images of our paper Rxs.
We are now working on digitizing all our ECGs and automating their interpretation.
