Polychoral is a UK-registered technology consultancy with a proven track record across the tech industry — spanning media and broadcasting, B2B SaaS, eCommerce, music technology, and geolocation. A formal mathematics background informs every layer of the work, from type-level abstractions to distributed systems modelling.
About
Polychoral is a specialist software consultancy incorporated in England and Wales, built on over eight years of senior engineering experience across media, B2B SaaS, automotive eCommerce, music technology, and geolocation. Clients have included Fortune 500 industry giants alongside early-stage startups in accessibility-focused and location-aware domains.
Every engagement draws on a broad, proven skill set: TypeScript backend engineering and distributed systems architecture at Limio; OpenSearch performance optimisation, Python data analytics, and engineering leadership at Limio; full-stack eCommerce delivery at Ford; cross-platform mobile development for a geolocation startup; and accessibility tooling for a music technology platform. Clean architecture and measurable outcomes are non-negotiable.
A formal background in mathematics shapes the approach throughout — from reasoning about type-level abstractions and distributed consistency guarantees, to tuning search relevance algorithms and modelling data pipeline behaviour. Precision is the starting point, not the finish line.
Engaging via a UK limited company gives clients a clear, IR35-aware structure — with the hands-on technical depth of a senior engineer and the precision of a mathematically-grounded practitioner.
Immediate starts available. Proven track record of delivering value from day one with minimal hand-holding required.
AWS-certified thinking applied to every solution — scalable, cost-efficient and resilient from the ground up.
Strongly-typed codebases that are a pleasure to maintain. Frontend, backend and tooling — TypeScript all the way down.
Engaging as a UK limited company. Accustomed to outside IR35 determinations and hybrid working arrangements.
A formal maths background informs algorithm design, type-level abstractions, consistency modelling, and search relevance — rigour that shows up in every codebase.
Services
A mathematically-grounded engineering practice spanning TypeScript back-ends, distributed systems, and full-stack delivery — built on first principles and shipped with precision.
Delivery of complete, production-ready web applications across frontend and backend. Led end-to-end development of a scalable Ford eCommerce platform that improved user experience by 40%, and built accessibility-focused interfaces for a music technology product built on Ableton Live.
Distributed systems design and deployment on AWS — including architecture reviews and security audits conducted at a major public service broadcaster. Experience with ECS/Fargate, Lambda, CloudFront, and pipeline reliability at scale.
TypeScript-first backend engineering focused on service quality and longevity. At a major public service broadcaster, led migration of core services to reduce inter-service dependencies and accelerate delivery. At Limio, resolved OpenSearch performance bottlenecks to deliver faster, more relevant search results.
Embedded senior leadership with a record of lifting teams. At Limio, mentored junior engineers through code reviews and pair programming — achieving a 20% improvement in test coverage and a 25% uplift in team retention. Promotes inclusive, high-trust engineering culture.
