Bespoke eLearning Architect | AI-Powered SCORM, PWAs & Custom Learning

Standard authoring tools often limit the scope of high-level educational projects. I bridge that gap by building custom, code-driven learning solutions using HTML5, CSS3, JavaScript, and reveal.js. With a background in higher education and research, I ensure that every project maintains pedagogical integrity while leveraging the latest in EdTech. Technical Focus: - AI-Integrated SCORM: Implementation of LLMs (Generative AI) within SCORM packages for real-time tutoring and adaptive feedback. - Progressive Web Apps (PWA): Offline-first, high-performance learning experiences that function seamlessly outside traditional constraints. - Custom Environments: Unique, brand-centric interfaces built from scratch, ensuring your content doesn’t look like a template. - Digital Credentials: Expert implementation of Open Badges 3.0 for STEM competency certification. Professional Commitment: As a Top Rated freelancer with a 100% Job Success score, I prioritize precision and clarity. My communication is efficient and professional, respecting your deadlines and project requirements through structured written updates. Ready to move beyond static slides? Let’s discuss how these technical capabilities can elevate your next project.
