Tom Tingle developed and maintained core features across the companieshouse/acsp-web and related repositories, focusing on secure, reliable user workflows for ACSP registration, updates, and closure. He engineered middleware-driven session and transaction handling, robust error management, and policy guardrails to enforce business rules, using JavaScript, TypeScript, and Node.js. Tom enhanced accessibility and localization, implemented analytics integrations, and improved data validation and persistence, particularly in MongoDB-backed flows. His work included refactoring for code quality, expanding test coverage, and modernizing CI/CD pipelines. These efforts resulted in resilient, maintainable services that improved user experience, data integrity, and compliance across the ACSP platform.

June 2025 performance summary across ACSP web and verification streams. Delivered guardrails and reliability improvements that enhance data integrity, user experience, and analytic quality while reducing business risk. Notable outcomes include (1) ACSP Ceased Status Safeguards across close/update flows and profiles with a CEASED constant and AcspCeasedError to enforce data integrity, (2) robust Close ACSP session/transaction handling to preserve the close transaction ID and prevent duplicates, (3) Ceased ACSP re-registration flow enabling re-engagement by redirecting to the type-of-business page, (4) accessibility and error handling improvements plus analytics cleanups to improve UX and reporting clarity, (5) identity verification guardrail preventing ceased ACSPs from undergoing identity verification. These changes were supported by CI/test infrastructure improvements and targeted analytics/data quality work in Matomo/Piwik as part of the ongoing quality program.
