At Matheson, Ireland’s premier law firm, I led the full-stack development team in delivering a transformative suite of internal enterprise applications serving nearly 1,000 staff. My flagship achievement was architecting and launching People Finder—a LinkedIn-style staff directory that revolutionized internal collaboration. This platform features dynamic profile photos, instant search, skills tagging, organizational charts, and integrated office floor plans, all automatically synchronized with HR and access card systems. Celebrated in a firm-wide launch and still running maintenance-free over 8 years later, People Finder set a new standard for internal software quality and longevity.
I also engineered an end-to-end Event Registration System, enabling seamless management of firm events with automated attendee tracking, analytics, and deep integration with staff directories. My technical leadership spanned database design (SQL Server), secure authentication (Active Directory), responsive web interfaces (ASP.NET MVC, jQuery, Bootstrap), and process automation—while mentoring junior developers and delivering comprehensive training across the firm.
Matheson’s leadership praised my attention to detail, strategic thinking, and collaborative spirit. My work empowered staff, streamlined operations, and established best-in-class internal systems that continue to deliver daily value and reliability—demonstrating expertise in full-stack architecture, enterprise integration, and high-impact solution delivery.
As Senior .NET API Developer and Cloud Architect, I designed and delivered TrialView: a production-grade legal document management platform now trusted by leading law firms across Ireland. TrialView automates the generation of professional trial books for courtroom use, featuring a sophisticated .NET Core REST API backend with Azure cloud deployment, dual-database architecture, and enterprise-grade security (Azure Key Vault, RBAC).
Key innovations include an advanced PDF processing pipeline—automatically merging documents, generating custom divider and index pages, and applying professional watermarking and sequential page numbering logic tailored for legal evidence presentation. The system efficiently manages large-scale document repositories, integrates seamlessly with Azure Blob Storage, and ensures robust error handling and audit trails through structured NLog logging.
TrialView has transformed trial preparation, reducing document collation time from days to hours while improving consistency, security, and compliance. This project exemplifies my expertise in .NET architecture, cloud infrastructure, complex file processing, and scalable API development for high-stakes, regulated environments.
Over a decade-long partnership with Ireland’s Department of Education, I architected and delivered five mission-critical enterprise applications, all still serving thousands of users nationwide. My work spans two major contracts (2015, 2020–2022), establishing a foundation of trust, technical excellence, and long-term maintainability across the national education system.
Highlights include the award-winning Translation Service Platform—a secure extranet serving 20+ external supplier organizations—which has operated flawlessly for over 10 years. I developed the bilingual Student Grant Appeals Board (SGAB) portal and School Transport Appeals (STA) platform, both replacing fragmented manual workflows with modern, accessible, and government-compliant digital systems. For the National Educational Psychological Service (NEPS), I delivered the PsyMIS Critical Incidents application, enabling precise workload analysis and national-level BI reporting. The ePlanning Strategic Governance Platform unified 25+ departmental divisions under a single action plan framework, achieving a 70% reduction in PMO report preparation time.
Technically, these solutions leverage SharePoint 2016/2019/Online, SPFx, React, TypeScript, ASP.NET, Power Automate, C#, Azure AD, SQL Server, and robust REST API integrations. I implemented multi-role RBAC, bilingual content, comprehensive audit trails, and government-grade security and accessibility (WCAG 2.1). My systems remain in active production, reflecting expertise in enterprise architecture, workflow automation, and high-impact public sector delivery.
At BCM Global, I led two consecutive contract engagements—spanning 19 months—as Senior SharePoint and Power Platform Developer, delivering a complete modernization of their enterprise collaboration infrastructure. I managed a large-scale migration from legacy SharePoint 2007/2010 environments to SharePoint 2019 (on-premise) and SharePoint Online, architecting and deploying the entire SharePoint Subscription Edition from the ground up.
My solutions included developing critical PowerApps for HR requisition and business workflow automation, seamlessly integrating them with SharePoint Online and Power Automate to enable end-to-end process automation. I executed complex content migrations using ShareGate and custom PowerShell scripts, ensuring zero data loss and minimal business disruption. The project encompassed advanced security and maintenance frameworks, SPFx component libraries for a consistent user experience, and comprehensive documentation and training programs to support ongoing adoption and maintenance.
BCM Global’s leadership commended the quality and reliability of my work, reflected in their decision to re-engage me for a second contract. This project showcases deep expertise in Microsoft 365, Power Platform, SharePoint administration and migration, and enterprise-scale automation—delivering measurable improvements in operational efficiency, security, and user experience.
