CALIBRA - Interactive Web-Based EdTech Platform for Automotive Measurement

Spearheaded the end-to-end development of CALIBRA, a web-based e-learning platform designed to solve the critical shortage of physical measuring tools in vocational schools (specifically for SMK Negeri 1 Cibinong). The platform facilitates hands-on learning for fundamental automotive engineering tools, such as the Vernier Caliper and Micrometer, through high-precision interactive digital simulations. Key Contributions & Features: Pedagogical Integration: Designed an adaptive learning architecture based on the Zone of Proximal Development (ZPD) to provide digital scaffolding, guiding students from theoretical knowledge to psychomotor mastery. High-Precision Simulations: Engineered real-time virtual manipulation of measuring tools (handling 0.01mm to 0.05mm precision scales) to build students' muscle memory and measurement intuition without requiring physical hardware. Progressive Gamification: Built a tiered evaluation system (Theory, Pattern Recognition, and Comprehensive Evaluation) that significantly boosts behavioral and emotional student engagement. Modern Development: Leveraged AI-assisted coding (Vibe Coding) paradigms to rapidly execute the Product Requirements Document (PRD) into a fully functional product. Tech Stack: Frontend: React.js, Next.js Backend & BaaS: Supabase, PostgreSQL Deployment & Tools: Vercel, GitHub
