How NHS Neuron Built an Enterprise HR Platform with Superblocks
A domain expert with no engineering background used Clark to build a 156-API platform serving 25,000 NHS staff.

HR tools being replaced by one app
"Our technology landscape, specifically across people digital — we have 25,000 members of staff and we found that they were using nearly 200 different tools just for delivering HR services."
NHS England has 1.5 million employees across 200 trusts. At just one of those trusts, 25,000 members of staff were using nearly 200 different tools just for delivering HR services. The Neuron team saw an opportunity to build something better.
With Superblocks, business teams now build their own enterprise-grade applications connected to live NHS data across Supabase, AWS, and Microsoft Entra ID. Lukas Saridis, a designer with no engineering background, built the entire platform.
Rethinking how a trust delivers HR
The NHS is the world's largest healthcare provider. Within a single trust, staff rely on dozens of disconnected tools for HR, procurement, recruitment, helpdesk, and case management. Each workflow operates slightly differently. Off-the-shelf enterprise software was never designed for this level of complexity and customization.
The Neuron team saw a different path: build one modular app that handles all of it, designed around the way their trust actually works.
"The size of team we have and the level of expertise we have — building an enterprise application to this complexity simply would not be possible without Clark."
The people who understood NHS workflows best weren't engineers. They were the staff living inside these processes every day. They just needed a platform that let them build without waiting on traditional development cycles. Superblocks gave them that path.
Subject matter experts become app builders
Lukas Saridis studied design. He had never connected to a database or shipped a production application. With Clark, the AI coding agent in Superblocks, he built one of the most sophisticated applications the platform has seen: 156+ APIs, 45+ pages, multi-factor authentication, role-based access control, and complex approval chains.
Clark as co-builder. Lukas describes what he wants to build. Clark generates the application logic, database connections, and API integrations underneath. 156 APIs and counting, built by a designer.
Governance handled centrally. EU cloud deployment, Microsoft Entra ID authentication, row-level security policies, and GDPR compliance. Lukas focuses on building. Superblocks handles the guardrails.
Connects everything. Supabase/Postgres, AWS Secrets Manager, Microsoft Entra ID, and REST APIs all integrate into one platform. No more moving data between 200 systems.
Built on Supabase + AWS
NHS Neuron runs Superblocks within a secure, EU-compliant infrastructure. The platform connects directly to Supabase/Postgres and AWS services, keeping data within NHS-approved environments while giving Lukas full access to build.
"As a leader, it's vital for me that whatever product we choose provides the guardrails and the security to know that the data is being used correctly. Superblocks not only provides that security for us, but it also gives us the creativity and the line within NHS guidelines."
Axon: All-in-one HR for the NHS
Axon is an all-in-one HR platform split into modules: establishment management, case management, recruitment, helpdesk, and more. The modular design means teams adopt only what they need and configure each module to their specific workflows.
Lukas built the entire application with Clark. The platform handles organizational structure visualization, fill rates, FTE management, dynamic approval chains, and a permissions system attached to posts rather than people, so access updates automatically when staff move roles.
Permissions attached to posts, not people. Every time an NHS staff member moves roles, permissions update automatically. No more manual access management across thousands of staff.
156 APIs and 45+ pages. Multi-factor authentication, role-based access control, org structure canvas, dynamic approval chains. Built by one person.
Replacing ~200 tools in one trust. One platform instead of hundreds of disconnected systems for delivering HR services.
"We've tried tools like Lovable and other IDE's, and they just don't have the enterprise-grade guardrails to make sure your application is secure, performant, and can scale."
5+ modules and growing
"With Axon built on Superblocks, our vision is to create an all-in-one HR solution for the NHS and wider, so that staff can focus on people and patient care."
Measurable outcomes. And a vision for what comes next.
"I have an idea, and the idea comes to life. My only limitation at the moment is my imagination."
