Founder + sole engineer

Founder and sole engineer behind InstaYolo. Built the site, runs the VPS, writes the technical blog. The /about page describes the team as 'one operator, some contractors for copy and translation' — that operator is me. I don't have a previous-company résumé to drop here; what's on this site is the work.

What I write about

·Instagram CDN URL signature anatomy (DASH manifests, the `efg` parameter, Meta's vencode_tag)
·Video codec pipelines — H.264 baseline vs VP9 vs HEVC, decode-time tradeoffs, ffmpeg -c copy remux
·Residential proxy networks for high-volume CDN reads without account attribution
·Next.js 16 + Cloudflare + Docker on a VPS — the boring infrastructure that keeps a downloader working at 3 AM
·Honest technical writing — no fabricated user counts, no fake AggregateRating, no 'unlock the power of' marketing slop

April 23, 2026Inside Instagram's DASH manifest — from MPD to segment to stitched MP4The first surprise when you reverse-engineer an Instagram Reel download is that there's no single MP4 to fetch. There's an MPD file, separate video and audio representations, and a bunch of segment UR…
