Unreal Engine C++ gameplay feature
A gameplay feature written in Unreal Engine C++ inside the client's own repository and contributor rules: gameplay video evidence, session logs and their automated checks all had to pass before review. It passed both stages of their QA.

3D models rebuilt from printer G-code
The client had only the sliced G-code for their printed cases, not the models. We rebuilt each part layer by layer into STL and editable STEP, then redesigned later versions to their notes. The final version printed perfectly, and the client now hires us directly.

AI sublimation-print design software
A photo of a finished jersey goes in; an editable CorelDRAW print file comes out, ready for sublimation printing, instead of being redrawn by hand. A second paid phase put it online as a web app the client's team works in, and every update has to pass a regression gate on their real designs before it goes live.

MetaTrader 5 basket trading bot
A multi-pair basket EA built to specification, with a per-trade backtest delivered alongside it. The analysis showed no edge at the 5-minute timeframe, and we disclosed that at delivery instead of hiding it in a total. The same client came back for two more orders, and both bots now run live.

How we work
Four things we always do
Checks before code
We turn the agreed requirements into pass/fail checks before building. On our last Illustrator job, the checks caught six defects in one day, and none of them reached the client.
We look before we call it done
Every page is rendered at phone and desktop width. A missing card, an empty spec table and a contradicted warranty were all caught this way, and none of them raised an error.
Honest numbers
Backtests are reported per trade, never as a flattering total. When a strategy had no edge, we said so at delivery.
Fixed price, fixed date
Both agreed before we start. Half up front, half on handover. If we misjudged the effort, that is our cost.
Built for busy owners
You run the business. We run the build.
No agency layer in between. One chat, one preview link and the person who builds it, from the first message to the handover.
One chat, start to finish
Every question, preview and decision sits in one WhatsApp or email thread. Nothing is scattered across tools you have to learn.
One link to check progress
From the first build you get a live preview link. Open it on your phone whenever you like; it always shows the latest version.
One person who builds it
The person you talk to is the person writing the code. Nothing is lost in a handoff between a salesperson, a manager and a developer.
FAQ
Questions we get asked
Who is Brain Grain Technologies?
Brain Grain Technologies (BRAINGRAIN TECHNOLOGIES LLP, LLPIN ADC-3296) is a software studio in Chennai, India, led by Amul R. We build web products, Shopify stores, mobile apps, AI automation and MetaTrader trading tools for clients worldwide, and run our own products on the same stack.
Do you work with clients outside India?
Yes. Our client work so far has come through Freelancer.com and MQL5 Freelance, including clients in Europe. We work in English, and our hours overlap with European mornings and US evenings.
How do you price projects?
A fixed price and a fixed delivery date, both agreed before we start, with half up front and half on handover. We do not bill by the hour.
What do you not do?
We do not sell link-building campaigns, ad management, or guaranteed rankings. For trading we do not promise profits; we build and test your logic and report the results honestly.
How do we start?
Open the Build for me page, add what you need to the cart (a business website starts at ₹4,990) or describe it in your own words, and press Start building. You can also message us on WhatsApp or book a 15-minute call on the How we work page. We reply with what is actually needed and confirm a fixed price and date before any work starts.
Have something to build?
Tell us what should happen that does not happen today, and your deadline. We reply with what we think is actually needed before we quote.
