Oylkka Graphics

• Give designers a dead-simple upload flow — drag, drop, add title/description, publish.
• Build fast search that works across thousands of assets with category and tag filtering.
• Optimize images on upload so the site loads fast even with high-res originals.
• Create a creator dashboard showing earnings, download counts, and asset performance.

Built this alongside Oylkka (the e-commerce platform), reusing the auth and payment infrastructure. The main new challenge was the image pipeline — I needed to generate thumbnails, WebP variants, and responsive sizes on upload. Deployed on Vercel with MongoDB Atlas.

• Challenge:

  Uploading 10MB+ source files was timing out on Vercel's 4.5s serverless limit.

  Solution:

  Moved uploads to a presigned URL flow — client uploads directly to cloud storage, then triggers a processing job via webhook.

• Challenge:

  The search was too slow once the library hit 2000+ assets — MongoDB text search couldn't keep up.

  Solution:

  Added Atlas Search (Lucene-based) with faceted search for categories, price ranges, and popularity scoring.

• Challenge:

  Creators wanted to see real-time earnings, but the payment webhook processing was asynchronous.

  Solution:

  Built a webhook handler that updates creator earnings immediately on payment confirmation, with a push notification via Server-Sent Events.

• Presigned upload URLs are the only way to handle large files in serverless — don't try to proxy through your API.
• Atlas Search is basically free Elasticsearch if you're already on MongoDB — worth the switch from text indexes.
• SSE (Server-Sent Events) is underrated for real-time updates when you don't need bidirectional communication.
