What this actually is

API Development & Integration, explained properly

Modern businesses run on integrations. Your CRM needs to talk to your e-commerce store. Your app needs to accept payments. Your support system needs to pull data from three different places. We build the APIs and integrations that make it all work seamlessly.

We build RESTful and GraphQL APIs from scratch for applications that need a robust backend, and we integrate third-party APIs for businesses that need to connect existing tools. From Stripe and Twilio to Salesforce and custom enterprise systems, we've integrated it.

Every API we build is documented, secured, versioned, and built to scale. We think about rate limiting, authentication, error handling, and monitoring from the start, not as afterthoughts.

What you get

VIX & Volatility Analytics Backend

We designed and built the entire backend for a VIX and volatility analytics platform. That covers the signal calculation engine, the VIX term month handling that maps each futures contract to the correct expiry so the curve is built in the right order, the charts APIs that feed the front end, the supporting services and the cloud infrastructure it all runs on. The platform shows the VIX futures term structure sourced from CBOE, contango as a percentage, the VIX1D, VIX9D, VIX30D, VIX90D, 3M and 6M indices, historical volatility over 10, 20 and 30 days, a table view and a speed tracker with news. Quotes refresh every minute, so the ingest and calculation path has to stay correct and fast on every cycle rather than only on a cold load.

Dispatch Portal Rebuild & Migration

Rebuilt the dispatch portal that runs day-to-day operations for a large Canadian transport company. The system was migrated off ASP.NET onto PHP and Laravel, then upgraded end to end: dispatchers assign loads and drivers, log trips, track vehicles and pull operational reports from one portal instead of several disconnected screens. The heavy work was on the data layer, where reworking the queries, indexing and payloads turned retrieving large datasets from something a dispatcher waited on into something that returns while they are still looking at the screen.

Event & Venue Management Platform

Built a full event and venue management SaaS that covers the whole lifecycle of an event. Organisers can sell in several ways from the same listing: standard ticketing, an external link, box office sales on the door, a waitlist, free RSVPs or pay what you want. Seats are picked from an interactive floor plan built in the seat chart builder. Payments run through Stripe and PayPal, with coupons, and ticket or whole-order transfers verified by one-time code. On the day, staff scan QR codes at the door as an assigned scanner team. Around that sits a venue directory with an approval workflow between organisers and admins, recurring events and templates, revenue and attendance analytics per organiser and platform-wide, a help desk, moderated reviews, newsletters and a media library.

questions

The things people ask before they commit.

Still have questions?

Call us: +44 7782 225572[email protected]

What's the difference between REST and GraphQL?

REST is simpler and works well for most use cases. GraphQL gives more flexibility for complex frontend needs where you want to fetch exactly the data you need. We'll recommend the right approach for your project.

Can you integrate with [a specific tool or API]?

Most likely yes. If they have a documented API, we can integrate with it. Tell us what you need on the call and we'll confirm.

How long does an API integration take?

Simple integrations (a single API, one-way data sync) take 1–5 days. Complex integrations with bi-directional sync and error handling take 1–4 weeks.

Do you write API documentation?

Yes. We provide Swagger/OpenAPI documentation for all APIs we build, and general documentation for integrations.

Will the API be secure?

Yes. All our APIs are built with security as a baseline: proper authentication, input validation, rate limiting, and HTTPS enforcement.
