Medication Management Application for Psychiatric Hospitals

Following design reviews with medical staff, I designed the underlying software architecture and led an Agile team in the development effort using .NET Core, React, and Microsoft SQL Server.

A tablet-optimized web app to aid in administering drugs in psychiatric hospitals. I designed a clear, task-focused UI to ensure that nursing staff could work most efficiently in the busy and often distracting environment of a mental health inpatient ward.

Following design reviews with medical staff, I designed the underlying software architecture and led an Agile team in the development effort using .NET Core, React, and Microsoft SQL Server.

The business outcomes included fewer medication errors, cost savings due to more efficient re-ordering from a central pharmacy, time savings by allowing doctors to remotely approve prescriptions, and improved oversight due to instant management reporting.

Temporary Staff Procurement Tool for Care Homes

A web application for coordinating temporary staffing requests across hundreds of care homes, based on ASP.NET MVC, Bootstrap, and Microsoft SQL Server. The application allows local managers to request staff for shift cover, whether planned or in response to emergency needs, then applies complex business rules to procure cover from the most appropriate local staffing agency according to the type of shift, time of day, holidays, etc.

BUSINESS BENEFITS
• Shifts are filled at the most economic hiring rates.
• Head office procurement staff have an overview of all the orders placed and the ability to keep area managers within budget while maximizing compliance.
• Individual workers' qualifications and experience are tracked while ensuring that the human touch overrides the algorithm.
• Home managers can request return shifts from high-performing workers and reject those who are not found to be a good fit.

Clinical Assessments Tool for Special Education and Mental Health

I designed the software architecture (ASP.NET, Microsoft SQL Server, and React) with an extensible schema to transition easily into other domains. This paid off when the system was swiftly adopted by the client's adult mental health division and after the acquisition of another business in the children's social care space. When the client sold that division, the IP in the solution was reckoned as a large part of the realized value.

A web-based clinical tool to measure and track the overall performance of special needs children, such as those with autism and/or learning difficulties, within residential school settings. Clinicians in various disciplines, such as psychology, occupational therapy, and speech and language, and educational staff used the tool.

Users were presented with domain-specific questionnaires that convert qualitative observations into numerical scores to guide decision-making about appropriate support and interventions and demonstrate to stakeholders that care plans resulted in positive outcomes. The observation and measurement methods were developed with clinicians, initially trialed using paper forms and manual calculations, and then validated by published research before committing to the project.
