Experience

Building product features for a creator-clipping platform across authentication, rewards, gamification, content, and automation, spanning frontend, backend APIs, and SEO.

• Strengthened account security with single-device session enforcement using Supabase GoTrue and server-side validation, invalidating older sessions and prompting re-authentication when an account is accessed from another device
• Built a seven-day consecutive-login onboarding system with Rp15,000 reward eligibility and a guided walkthrough covering profile completion, campaign discovery, brief review, video upload, and withdrawal
• Developed a weekly Clipper leaderboard and five-tier progression system for Base, Verified, Certified, Professional, and Elite Clippers, combining view thresholds, 0–20% campaign bonuses, and monthly rank reviews
• Built an SEO-ready blog system using dynamic metadata, structured data, tables of contents generated automatically from H2 headings, and FAQ schema, and automated daily Discord activity reports through cron jobs and webhooks

• Built the backend domain from scratch using Express.js and strict TypeScript, delivering 76 endpoints across student and admin workflows, 22 PostgreSQL tables, and 23 additive migrations on a shared production database serving approximately 150,000 accounts
• Unified authentication across Konten.com and Kelas Clipper through a single Supabase GoTrue tenant, letting existing users sign in directly while automatically provisioning clipper accounts, wallets, and roles for email/password, Google PKCE, and payment-based registrations
• Secured the 24-hour trial and paid-subscription lifecycle using compare-and-set activation, idempotent Xendit invoice and webhook processing, callback-token validation, and double-entry ledger records
