Financial software is ordinary software with an unforgiving audience: a regulator, a security reviewer and a customer moving real money.

We built and maintain the e-commerce and trading platform for a London bullion dealer, where every price is derived continuously from the world market rate by weight and purity and has to hold from listing through basket to payment. Around it sit mandatory identity checks, insured high-value fulfilment and an inspection-led sell side so customers can trade back.

That engagement is the reason we talk about quote integrity, settlement and identity verification as engineering problems rather than features. Every capability described on that case study is visible on the client’s own live site, so you can check it in a click.

We work to Western procurement, security-review and compliance expectations as an offshore partner, and we put data-residency and access constraints in writing before development starts.
