Stack
Challenge
HighLevel users needed a flexible way to design and issue certificates for course completions and achievements. The solution required a non-technical design tool, bulk issuance, secure verification, and deep integration with HighLevel's workflows and Membership system.
Solution
Built a complete Credentials module from scratch with a WYSIWYG Certificate Builder (drag-drop elements, templates, real-time canvas preview), Badge Designer, automated issuance workflows (CSV bulk upload, scheduled sends), public shareable credential links with social sharing, UUID-based verification API, and analytics dashboard tracking engagement.
Context & Background
Multi-tenant SaaS platform requiring white-label branding, secure credential verification across internal apps, and seamless integration with HighLevel's Memberships/Courses product. Needed to handle high-volume issuance and provide a premium design experience.
Key Contributions
Architected and built the Certificate Builder with drag-drop UI, templates, logos, QR codes, custom fonts/colors, watermarks, and background images
Developed Badge Designer on the same Canvas engine for circular badge graphics with icons, ribbons, and customization
Implemented bulk issuance: CSV upload with dynamic fields, auto-send emails, scheduled issuing, and renewal workflows
Created Credential Portal: login-free access via public links, branded portal, social sharing (LinkedIn, Facebook, X/Twitter, WhatsApp)
Built verification system: UUID-based IDs, public validation API, issuer identity verification, and revocation controls
Added analytics dashboard: track opens, link clicks, verification requests, social engagement, and monthly performance reports
Integrated with HighLevel workflows: trigger certificate/badge issuance from course completions, form submissions, and other internal events
Implemented certificate expiration with automated renewal reminders (customizable lead times)
Technical Architecture
Built as a standalone micro-frontend using Module Federation (Webpack 5). Canvas-based editor with custom rendering for PDF/PNG export. Backend APIs handle bulk processing, email automation via HighLevel workflows, verification endpoints, and analytics aggregation. Real-time preview with optimized state management.
