Compliance-grade software, with the patience to ship it well
Meridian Systems builds back-office software for regulated industries: clinical trial coordination, financial reconciliation, public-sector procurement. We work alongside your in-house team for 12-to-18-month engagements and stay on for the long maintenance tail nobody else wants.
What we deliver
- Audit-ready code — every change traces back to a ticket, every ticket to a requirement, every requirement to a stakeholder sign-off
- Zero JavaScript on customer-facing pages — the most accessible, fastest, and most cacheable HTML you can ship
- WCAG 2.1 AA compliance — automated and manual testing, signed off before every release
- EAA-ready by default — every site we ship after June 2025 meets European Accessibility Act baseline
- CSP, HSTS, COOP, COEP — security headers configured per OWASP guidance, not the framework defaults
- 30-day uptime SLA — 99.95% measured at the customer's edge, not at our load balancer
Recent client work
- NHS England — clinical trial recruitment portal serving 137 trial sites, WCAG 2.1 AA, full audit trail
- Crown Commercial Service — supplier reconciliation tool processing £2.4B in annual contracts
- Bank of England — internal tooling for the Prudential Regulation Authority (under NDA — happy to discuss in person)
How we work
- Two-week paid discovery. We document the system as it stands today and write down the constraints we'd otherwise miss.
- Co-located team for the first quarter. Our designers and engineers sit with yours; nothing happens in a Slack channel they can't see.
- Fortnightly demos to stakeholders. Every Wednesday, every fortnight, no slides — just the working software.
- Open handover from day one. Source, decision records, and runbooks live in your repo, not ours.
Why teams hire us
- No surprise invoices. Fixed-price discovery, time-and-materials with monthly caps after that.
- No subcontracting offshore. The names on the proposal are the people who write the code.
- No five-year exit cliff. Maintenance contracts are renewed annually with a 90-day exit clause both ways.
