National grocery retailer (confidential)

Nationwide digital signage rollout for a supermarket chain

A national supermarket chain relied on printed posters and shelf-edge cards for every promotion. We designed and rolled out a store-wide digital signage network with central scheduling, so a national campaign goes live from head office in minutes instead of weeks.

Predictive maintenance for airport facilities with IoT Facilities management / Aviation
Major airport (confidential)

Predictive maintenance for airport facilities with IoT

A major airport maintained over a million square feet of terminal reactively: HVAC, lifts, escalators and baggage systems were fixed after they failed. We built an IoT-driven facilities platform that sees faults coming and schedules the work before passengers notice.

PredictiveFaults flagged before failure

Smart-building energy and compliance platform for a large hospital Healthcare / Facilities management
University teaching hospital (confidential)

Smart-building energy and compliance platform for a large hospital

A 600-plus-bed teaching hospital had a multi-million-pound energy bill with no visibility by department, and ventilation compliance checks that relied on engineers walking the site with clipboards. We delivered a smart-building platform that meters, monitors and reports automatically.

Department-levelEnergy visibility instead of one site total

AI-assisted traffic management for a city council Smart cities / Transportation
City council (confidential)

AI-assisted traffic management for a city council

A city centre's traffic signals were still running fixed timing plans set years earlier, with hundreds of junctions operating independently. We built a coordinated, AI-assisted traffic-management platform that adapts signal timing in real time to what is actually on the road.

Real-time fleet intelligence for a national logistics operator Logistics / Transportation
National logistics operator (confidential)

Real-time fleet intelligence for a national logistics operator

A logistics business running thousands of vehicles across the UK had no live view of its fleet: dispatch worked by phone, ETAs were guesses and fuel and driving behaviour went unmonitored. We delivered a real-time fleet-intelligence platform with dispatch, tracking and driver tools in one place.

Precision-engineering manufacturer (confidential)

Industrial IoT on a precision-engineering shop floor

A precision-engineering firm ran its CNC machining lines well below industry benchmarks for equipment effectiveness, with downtime recorded on paper and maintenance entirely reactive. We connected the machines and gave the floor live data, OEE dashboards and predictive alerts.

Patient-record integration across a multi-hospital NHS trust Healthcare / NHS
NHS hospital trust (confidential)

Patient-record integration across a multi-hospital NHS trust

A trust spanning more than a dozen hospitals ran several different electronic health record systems that could not share data. We built a FHIR-based integration platform giving clinicians one view of a patient's history across every site.

Primary care network (confidential)

A patient app that cut missed GP appointments for a primary-care network

A group of GP practices serving tens of thousands of patients relied entirely on phone booking, with long hold times and a high no-show rate. We built a patient app for booking, reminders and repeat prescriptions, integrated with the practices' clinical system.

A full property portal for a multi-branch estate agency Real estate / PropTech
National estate agency (confidential)

A full property portal for a multi-branch estate agency

An estate agency with dozens of branches depended on third-party property portals for almost all of its leads, with no direct relationship with buyers online. We built its own end-to-end portal — search to offer to exchange — with virtual viewings and a mobile experience.

Search → exchangeWhole buyer journey in-house

AI-assisted recruitment platform for a large retailer HR / Retail
National retailer (confidential)

AI-assisted recruitment platform for a large retailer

A retailer hiring thousands of people a year across more than a hundred sites was drowning in CVs. We built an AI-assisted recruitment platform that screens, ranks and schedules — so hiring managers spend their time interviewing, not sorting.

Long-haul travel agency (confidential)

A multi-supplier booking platform for a specialist travel agency

A specialist long-haul agency built every itinerary by hand across a dozen supplier portals — hours per quote while customers expected instant prices. We built a booking platform that assembles flights, hotels and transfers from all suppliers in minutes and lets customers book online.

Package holiday operator (confidential)

A personalisation engine that lifted ancillary sales for a holiday operator

A mid-market holiday operator was selling far fewer extras — transfers, insurance, excursions, upgrades — than the industry norm, because every customer got the same generic emails. We unified their customer data and built a personalisation engine that offers the right extra at the right moment.

Tier-1 fintech (confidential)

A real-time compliance engine for a tier-1 fintech

Onboarding an institutional client took days of manual compliance checks across half a dozen internal systems, and regulatory reports were assembled by hand. We built a real-time compliance engine that automates the checks, the decisions and the reporting.

Payments fintech (confidential)

Scaling a fintech platform to tens of millions of transactions a month

A fast-growing payments company was hitting database timeouts at a few hundred thousand transactions a day, with engineers spending most of their time firefighting infrastructure. We re-architected the platform for multi-region resilience and let the team get back to building product.

From no security programme to SOC 2 ready in twelve weeks

A SaaS company had an enterprise contract on the table that depended on SOC 2 Type II readiness within three months — with no security team, no controls and no prior compliance experience. We ran the programme end to end.

Scaling a fintech engineering team fast without losing velocity Fintech / Staff augmentation
Series-B fintech (confidential)

Scaling a fintech engineering team fast without losing velocity

After a Series B raise, a fintech had product commitments its eight-person engineering team could not deliver, and local hiring for its Go, React and AWS stack would take most of a year. We stood up embedded engineering squads that quadrupled capacity in five months.

Re-engineering a legacy retail platform for ten times the peak traffic

A decade-old monolithic e-commerce platform slowed to a crawl and regularly fell over during seasonal campaigns, with pages taking many seconds to load and a third of checkouts abandoned. We re-engineered it to handle an order of magnitude more concurrent shoppers.

B2B data-integration SaaS (confidential)

Monolith to microservices with zero downtime

A half-million-line legacy monolith had become a bottleneck for a SaaS company: slow releases, outage risk in every deploy and engineers who did not want to work on the stack. We migrated it to microservices incrementally, without a single planned outage.
