My journey in independent R&D began with a fundamental frustration: why should essential design and compliance tools be locked behind expensive subscriptions, rigid interfaces, or inaccessible complexity? As a self-employed developer with a background in architecture and business, I set out to create solutions that challenge this status quo—tools that are accessible, customisable, and intelligent, empowering users rather than restricting them.
At the core of my work are two flagship tools:
SPEC-U-Value Calculator™ – A dynamic thermal performance analyzer built to BS EN ISO 6946:2017 standards
SPEC-U-SAP Compliance Calculator™ – A streamlined solution for UK Building Regulations (Part L & SAP compliance)
But these are more than just calculators—they represent a philosophy: expert-level insights should be available to everyone, from students to seasoned professionals.
Developing professional-grade web applications like these requires a blend of technical precision, user-centric design, and AI-augmented problem-solving. Here's how I approach it:
Front-End (UI/UX):
Built with HTML5, CSS3, and JavaScript (ES6+) for responsive, interactive interfaces
Tab-based navigation for seamless switching between calculation types (walls, roofs, floors)
Dynamic form handling – adding/removing material layers, real-time validation
Mobile-first design ensuring accessibility on all devices
Back-End & Logic:
Pure JavaScript calculations for thermal resistance (R-values) and U-values
PDF report generation using jsPDF + jsPDF-AutoTable for professional documentation
Data persistence (local storage) to save user inputs between sessions
AI-Assisted Development:
LLM-powered debugging (ChatGPT, Claude) to troubleshoot complex JS functions
Prompt-engineered code refinement – optimizing algorithms for accuracy & speed
Automated documentation – using AI to generate clear technical specs
BS EN ISO 6946:2017 integration – precise thermal calculations
UK Building Regulations (Part L) adherence – ensuring real-world applicability
Mathematical rigor – correct handling of λ-values, Rsi/Rso resistances, and air gaps
Static site hosting (Netlify/Vercel) for fast, secure delivery
Future-proof architecture – designed for easy expansion (new calculation modules, user accounts)
Monetization-ready – subscription models or one-time licensing options
Architects – Quickly test insulation strategies without manual calculations
Architectural Technologists – Generate compliance-ready reports for planning submissions
Building Contractors – Verify material specs meet thermal requirements
Energy Assessors – Cross-check SAP inputs and streamline audits
University Lecturers – Teach thermal physics through interactive examples
Architecture Students – Learn Building Regulations via hands-on tools
DIY & Self-Build Learners – Understand U-values before purchasing materials
Self-Employed Architects – Reduce time wasted on repetitive compliance checks
Property Developers – Optimize designs for both performance and cost
Home Renovators – Avoid costly mistakes by modeling insulation upgrades
Beyond calculators, I'm developing a suite of AI-powered tools to help small businesses:
✔ Automated Project Management – Time tracking, invoicing, client communications
✔ Smart Compliance Assistants – Real-time regulation updates for construction
✔ Generative Design Prototyping – AI-assisted spatial planning
The future of work isn’t just about automation—it’s about augmentation. By combining:
Domain expertise (architecture, compliance, business)
Full-stack development skills (front-end, back-end, UI/UX)
AI-assisted workflows (coding, debugging, documentation)
I’m building tools that don’t just calculate—they educate, optimize, and empower.
Let’s connect if you believe in:
Democratizing professional-grade software
AI as a collaborator, not a replacement
Smarter, faster, more profitable workflows
