Sinara Build: Bespoke System Development

Custom systems for financial markets, built end to end

When off-the-shelf won’t do, Sinara designs, builds and runs bespoke operational systems for capital markets.

From first concept to live production — and long-term support beyond — we take on the whole project, with engineers who understand the markets as well as software.

End-to-End Software Development

Bespoke operational systems, built by people who understand the markets

A lot of what a trading business needs can be met by configuring or extending proven products — and where that’s the right answer, we’ll point you to SinaraTLC.

Bespoke development is for everything else: the requirements so specific to your business that no off-the-shelf system fits.

When a problem is genuinely unique, or ownership matters, it takes new software built properly — scoped, designed, engineered, integrated, deployed and supported by a permanent team that speaks the language of trading, risk and market operations.

That’s what Sinara does.

Why Sinara

The team you turn to for bespoke software

Purpose-built operational systems

When a new product, service or process is unusual enough that no off-the-shelf system fits, we build the operational platform it actually runs on — engineered to fit the workflows, robust enough to run from day one, and owned by you if that’s what you want.

Modernising internal & operational systems

Not every project is client-facing. We replace fragile spreadsheets, manual workflows and ageing internal tools with bespoke software that’s reliable, auditable and built to scale with the business.

We handle every part of development

Requirements and discovery, architecture, UX and interface design, engineering, testing, integration and deployment all under one roof. You get a single accountable partner for the whole build.

Engineers who understand the markets

Our permanent, full-time teams are steeped in capital markets, so they engage as informed partners from the first conversation. They grasp the nuances of your business — and the intricacies of a specific asset class — quickly, and turn them into the right software. And because they’re not a rotating pool of contractors, that understanding stays with the people who build your system and keep evolving it.

Designed to integrate

New systems rarely live in isolation. We build to fit your existing trading ecosystem — market data, connectivity, downstream risk and settlement, internal services and APIs — so the new system slots into your landscape rather than fighting it.

Production-grade from day one

Enterprise-quality engineering is the baseline: containerised, scalable architecture, rigorous testing, and the security and resilience institutional trading demands.

Accelerate with ready-made products

You don’t have to build everything from scratch — where it helps, and if you want to, we can bring in proven components from our SinaraTLC suite — trade lifecycle, order management and CTRM building blocks — to cut delivery time and cost, then extend and tailor them around you. Prefer a fully bespoke build with no Sinara products? That’s entirely your call.

Hosted and monitored, if you want it

We can run your system for you — hosted on a dedicated cloud tenancy, fully managed and monitored 24×7. Prefer to run it yourself? Deploy it on-premise or in your own cloud, and keep Sinara on as third-line support behind your team. The choice stays yours.

Support on your terms

Once it’s live, we can support it for as long as you need: 24/7 cover, maintenance, and a pipeline of new features and enhancements at your request, with short lead times. Or take full ownership with a clean handover. Either way, you’re never locked in.
