Work Experience

Developer

ShadowWall

Jan 2025 - Present

Engineered synthetic fake camera and microphone streams injected directly into the MediaStream API — websites receive a realistic black screen and silent audio instead of real feeds, remaining completely undetectable to anti-extension scripts. Implemented self-protecting toString() override that hides the protector itself, making all 41 API interceptions appear as native browser code — verified resistant to FingerprintJS Pro and Cloudflare bot detection. Built WebRTC IP leak protection by intercepting RTCPeerConnection API to strip real ICE candidates — prevents IP exposure even when a VPN is bypassed at the browser level. Achieved complete fingerprint neutralization across 12 tracking signals: Canvas noise injection, WebGL GPU spoofing, AudioContext randomization, font timing attack prevention, and 15-point User-Agent profile rotation. Developed hybrid IndexedDB + chrome.storage log system supporting up to 1 lakh tamper-proof entries (HMAC-SHA256), with batched writes producing zero browser lag and all-time tracker counters surviving restarts. Deployed with context isolation making the extension invisible to anti-extension fingerprinting, blocking 100,000+ tracker domains via auto-updating filter lists from EasyPrivacy, EasyList, Peter Lowe, and Steven Black.

Personal Domain Infrastructure

Jan 2025 - Present

Configured full Cloudflare DNS zone including A, MX, CNAME, and TXT records for custom domain hosting and email routing. Implemented complete email authentication stack (SPF, DKIM, DMARC) eliminating spoofing attack surface for the domain. Enabled Cloudflare CDN, DDoS protection, and HTTPS/TLS termination for hosted blog and portfolio — zero downtime since deployment.
