Custom Software, AI Automation & Data Platforms
I'm Ger O'Sullivan — an independent software engineer and product builder based in Ireland 🍀. I partner with organisations to design, build, and ship full-stack platforms: from AI-assisted tools and document-intelligence pipelines to compliance-grade systems for healthcare, professional services, and education.
What I do
End-to-end product development — from strategy and architecture through hands-on engineering and ongoing support.
Custom Software & Full-Stack Product
- Full-Stack Development: Building web applications with modern frameworks — React, Next.js, Node.js, and TypeScript.
- System Integration: Connecting new solutions to existing infrastructure, databases, and third-party services.
- Hosting & Maintenance: Reliable cloud hosting, ongoing support, and maintenance.
AI & Intelligent Automation
- Document Intelligence: OCR and table-extraction pipelines (e.g. AWS Textract) that turn PDFs and statements into structured, system-ready data.
- AI-Enhanced Features: LLMs, RAG, and ML for personalisation, insight, and automation.
- Process Automation: Streamlining workflows and removing manual, repetitive tasks.
Platforms for Regulated Sectors
- Compliance & Audit: Role-based access, audit trails, and data-protection-aware design.
- Secure Integration: Safe, read-first integration with existing systems of record.
- Learning & Training Platforms: LMS and EdTech (Canvas, Moodle, SCORM, Articulate) — one of several domains I work across.
Selected Work
A few projects that show how I take products from first sketch to production.
ICGP Clinical Placement Platform
A placement-management system of record for a national GP training network, replacing spreadsheet and legacy workflows. Taken from domain brainstorming through a working prototype to an enterprise-grade build with SSO, role-based access, full audit trails, and safe integration with existing training-records systems.
PackCheck
A white-labelled document-intelligence service for an accountancy practice. Clients upload year-end paperwork to a branded portal; the system checks completeness automatically and uses OCR to turn bank statements into accounting-software-ready data — ending the manual chase.
More of my work
Teachers Pet
An AI-powered educational ecosystem combining a teacher-facing web portal for lesson planning and student insights with a student-facing app featuring an adaptive AI learning companion.
Learntime
Modern open-source learning platform featuring evidence-based spaced repetition, adaptive personalisation, and multi-format content delivery. Built with scalable architecture supporting thousands of concurrent learners.
iheed Medical Training Platform
Award-winning healthcare education system featuring a content management platform that reduced authoring costs by 75% and comprehensive clinical training simulations. Successfully deployed across multiple healthcare organisations serving 10,000+ professionals.
Why work with me
I bring 20+ years of experience delivering mission-critical platforms for healthcare, education, and public sector organisations — from full-stack web development to applied AI and automation.
Proven delivery in regulated sectors
I've delivered learning platforms, compliance and training systems, and web applications serving over 10,000 professionals across healthcare and education.
End-to-end ownership
I take projects from first requirements through prototype, enterprise build-out, deployment, and ongoing support — including migrations and integration with existing systems.
The bridge between tech and business
I translate complex technical challenges into clear, client-focused solutions, keeping engineering aligned with your goals and your users.
Practical, measurable results
My work focuses on cutting manual effort and operational cost through efficient architecture and automation — for example, an authoring system that reduced content costs by 75%.
About me
I'm Ger O'Sullivan, an independent software engineer and product builder working from Ireland 🇮🇪 under the name Robot Nerd Face. With over 20 years of experience, I design and build comprehensive technology solutions for education, healthcare, and professional-services organisations.
My work is defined by shipping mission-critical systems end to end. I'm the founder behind Learntime.ai, a modern learning platform with adaptive capabilities. As Head of Engineering at iheed I led healthcare training systems serving over 10,000 professionals and built an award-winning authoring platform that dramatically reduced content costs.
My strength is the full span of the work: from architecture and integration to hands-on development and ongoing support. I work with organisations that need a reliable technology partner — whether that means building something new or modernising what they already have.
