Case studies

Selected work, measured by what changed.

A few anonymised examples of technical work across established systems, specialist products and large digital portfolios.

Performance optimisation

Lower infrastructure load across a large hosting estate

Overhauled an inefficient, memory-intensive system running on infrastructure shared by more than 120 systems.

32% reduction in CPU utilisation

The challenge

A high-traffic background process was consuming disproportionate memory and CPU on infrastructure supporting a broad portfolio of business-critical systems.

The approach

Profiled the workload, traced the most expensive execution paths and reworked the processing model to reduce repeated work and memory pressure. The changes were introduced carefully to protect neighbouring systems.

Profiling
Systems analysis

Bespoke product engineering

Sports science and movement-analysis platforms

Led technical work across bespoke applications used to collect, process and present specialist movement data.

Cross-platform systems delivered from API to mobile

The challenge

Specialist teams needed dependable software spanning web applications, cloud services, APIs and a mobile experience, all shaped around domain-specific workflows.

The approach

Led the technical delivery of connected PHP and Azure applications, designed REST API capabilities and contributed to a Unity/C# mobile app, keeping the architecture practical across a varied stack.

Portfolio support

Ongoing modernisation of LAMP-based websites

Supported and improved a large portfolio of established websites while keeping day-to-day operations moving.

Safer, more dependable sites with useful new features

The challenge

A varied estate of established sites needed responsive maintenance, security attention and feature work without the cost or disruption of wholesale replacement.

The approach

Investigated and resolved defects, tightened vulnerable areas and delivered focused enhancements. Work was prioritised around operational risk and business value rather than unnecessary rewrites.

A note on confidentiality

The useful detail, without exposing client information.

Client names and identifying details are intentionally omitted. More context about relevant experience can be discussed privately where confidentiality allows.
