What PETER MILLER SOFTWARE LTD does

Peter Miller Software Ltd is a UK-based, founder-operated contract software engineering consultancy providing senior React and frontend engineering services to B2B clients. The company is effectively a single-person professional services firm, with director and principal engineer Peter Miller personally delivering all engagements from the company's headquarters in Leamington Spa, Warwickshire. Service delivery spans six core modules: React & Frontend Development, Architecture & Technical Leadership, Performance Optimisation, Design System & Component Libraries, Code Quality & Testing, and Full-Stack & API Integration, with technology centred on React, TypeScript, Next.js, Node.js, GraphQL, and supporting tooling (Tailwind, Redux, Jest/Vitest, Cypress, AWS).

The business model is pure professional services revenue on a project or time-and-materials basis, with pricing determined per engagement and no publicly disclosed rate card. Go-to-market is direct B2B engagement driven by enquiry and personal network, supplemented by a minimal LinkedIn and GitHub presence — there is no formal marketing function. Customers are horizontally distributed across politics, e-commerce, emergency services, legal, healthcare, insurance, and construction. The firm positions insurance, IR35 compliance (via Kingsbridge), WCAG 2.2 accessibility expertise, and architectural-integrity-led engineering as primary differentiators against speed-oriented contractor alternatives.

Operationally, the company is a private limited company incorporated in the United Kingdom, founder-owned with no external investment, subsidiaries, or M&A activity. No funding rounds have been raised and no revenue figures are publicly disclosed. Capacity is inherently constrained by the single-deliverer model, with the firm's website reserving the right to provide a qualified substitute — signalling an awareness of key-person risk, but no evidence that a substitute has been deployed.
