Disciplines

Engineering across the whole delivery surface.

From a single automation script to a regulated multi-region platform — scoped, built, hardened and handed over with documentation.

01

Custom Software

Bespoke line-of-business systems designed around your process instead of forcing your process around off-the-shelf software.

02

Automation & Integration

Scraping, scheduling, document pipelines, ETL and system-to-system integration that removes manual handling entirely.

03

AI Integration

LLM-backed features, RAG pipelines, agentic workflows and model routing — with cost, latency and safety controls built in.

04

Legacy Rescue

Undocumented VBA, unsupported frameworks, orphaned servers. Assessed, stabilised, then migrated without a big-bang rewrite.

05

Cloud & DevOps

Containerised deployments, infrastructure as code, CI/CD pipelines, observability and cost-aware architecture.

06

Security & Compliance

Hardening, authentication, audit trails and remediation work aligned to OWASP, GDPR, Cyber Essentials and ISO 27001.

07

Embedded & IoT

Firmware, sensor networks and device fleets on constrained hardware, with telemetry back to systems that can act on it.

08

Web & E-commerce

Performance-first sites, headless storefronts, payment and fulfilment integrations, plus CMS builds that non-developers can run.

Technology

The stack we build on.

A working inventory — not a wishlist. If something isn't listed, it is almost certainly still in remit; ask the terminal.
