Media-rich SaaS platforms, photography/design marketplaces, and e-commerce stores spending thousands of dollars a month on AWS S3 egress fees or slow image rendering frequently search to hire a freelance Cloudflare R2, S3 presigned upload & dynamic image transformation CDN (`imgproxy`, `Sharp`, Cloudflare Images) programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack & Cloud Programmer.
Core High-Speed Media Storage & Image Delivery Capabilities
- Zero-Egress S3-to-Cloudflare R2 Migration: Migrating multi-terabyte AWS S3 buckets to Cloudflare R2 using incremental background sync workers and dual-read fallbacks—eliminating $0.09/GB AWS egress fees completely.
- Direct-to-Storage Presigned Multipart Uploads: Uploading 10MB–50GB files directly from React / React Native clients to S3/R2 via presigned URLs so file bytes never bottleneck your application servers.
- Dynamic On-the-Fly AVIF/WebP Resizing (`imgproxy` / Cloudflare Workers): Serving HMAC-signed, responsive `srcset` images resized and converted to AVIF/WebP at the CDN edge with BlurHash / ThumbHash instant placeholders.
Frequently Asked Questions
How do you prevent users from abusing presigned upload URLs to upload malware or 100GB files?
I enforce cryptographically signed S3/R2 POST policies (`content-length-range`, allowed `Content-Type` prefixes, SHA-256 checksums) and scan uploaded objects asynchronously via ClamAV / magic-byte verification workers before marking them public.
How do I hire you for media pipeline and CDN optimization?
