High-concurrency platforms
Built for the spike on launch day, because the average day will not break anything.
Fintech
Fintech software built for the first day of real traffic
Platforms that carry thousands of concurrent users from launch, and the controls around money that regulators expect. We shipped the first phase of one in a month.
30,000+Concurrent users the platform was built for

What this is
Scale and compliance arrive on the same day
A launch in a regulated market has a traffic problem and a promotions problem at once. The architecture has to absorb the spike, and the product has to carry the wording the regulator requires.
Microservices from the first sprint
The platform we built used a microservices architecture with AWS Kinesis, so traffic spikes scaled without a rewrite.
Senior developers, briefed once
A handpicked full-stack team and a clear brief let the first phase ship in a month.
Services
What we build for fintech teams
Event streaming on AWS
Kinesis and related services for traffic that arrives in bursts.
Reward and wallet mechanics
Earn, hold and pay-out flows with an audit trail behind them.
Payment flows
Checkout and pay-out paths with failure handling written down first.
Onboarding and verification
The steps that stand between a visitor and an account.
Reporting and ledger tooling
What came in, what went out and who it belongs to.
Regulation
What the UK crypto promotions regime asks
In force since 8 October 2023, and it applies to firms based overseas as well.
Who it coversAll cryptoasset firms marketing to UK consumers, including overseas firms, whatever technology makes the promotion.
Lawful routesA promotion can be communicated by an authorised person, approved by one, or made by a cryptoasset business registered with the FCA under the money laundering regulations.
Restricted mass market investmentQualifying cryptoassets are treated as restricted mass market investments, so promotions carry a mandatory risk warning.
Incentives to investThe FCA has banned incentives to invest, which matters for any reward or referral mechanic.
Case study
A launch in a month, for 30,000 concurrent users
Fintech, Hong Kong
Cryptocurrency marketing platform
A Hong Kong business wanted a blockchain-powered site connecting thousands of users, earning cryptocurrency through games and watch-to-earn ads. It had to support 30,000+ concurrent users with one month for the first phase. We delivered on microservices and AWS Kinesis, with .NET and Angular.

FAQs
What buyers ask first
Can you build under a hard deadline?
Yes, when scope is cut to one phase and the team is briefed once. The platform above shipped its first phase in a month.
Do you handle FCA compliance?
No. Compliance advice comes from your lawyers. We build the controls they specify, such as risk warnings and promotion gating.
Can the platform take a traffic spike?
That is the first design question. Microservices and event streaming on AWS kept the platform above responsive for 30,000+ concurrent users.
Who owns the code and the cloud accounts?
You do, from the first commit. Repositories and cloud accounts stay in your name.
