I'm Eshank Tyagi (known across engineering ecosystems as MrEshank)—a founding full-stack engineer and web systems architect building at the intersection of in-browser WebAssembly, local-first computing, and enterprise AI data security.

• 🛡️ Founding Full-Stack Engineer @ Matters.AI: Architecting AI-native enterprise data security platforms from 0 to 1—safeguarding sensitive data workflows across cloud, SaaS, endpoints, and distributed services with zero unauthorized leakage.
• ⚡ Local-First Computing & Client-Side Sovereignty: Heavy advocate for executing compute directly on user hardware. Leveraging WebAssembly SIMD, Web Workers, and offline data structures to deliver native application power in the browser with 0-byte network footprint.
• 🛠️ Developer Tools & Open Source: Creator of brutalist file conversion instruments (convrtr), browser DAWs (notater), published npm developer CLIs (pkill-port, mret), and modular architectures (METUI).
• 🎤 Community & Mentorship: Speaker at Google DevFest and Lead Engineering Coach at Explorin Academy, having guided 100+ software developers into production engineering careers.
• 🥁 Offline: Drumming enthusiast, music composition, sound exploration, and fitness.

An open-source, brutalist, privacy-first file conversion instrument. 100% of transformations execute locally inside client Web Workers with WebAssembly. Zero files ever leave the browser.

• 280+ Format Transformations: Audio, Video, Image, Document, Data, and Archives.
• WASM Stack: FFmpeg WASM, SQLite WASM, Libheif, 7z WASM, Apache Arrow SIMD.
• Chrome Extension: Side Panel, Omnibox trigger, context-menu viewport capture.
• Architecture: Next.js 16, TypeScript, Web Workers, Playwright network-leak invariants.

🌐 Web App • 🔌 Chrome Extension • 💻 Source Code

An offline-first, collaborative music production environment running entirely in the browser. Zero installs required—instant jam and audio synthesis.

• Real-time P2P Collaboration: Peer-to-peer note sync via WebRTC data mesh with zero central server latency.
• Pro Synthesis Engine: Polyphonic synths, dynamic sampling, DSP effect racks.
• Dynamic Cadence: Algorithmic rhythm assistant generating dynamic drum cadences.
• Ecosystem: Next.js, Tone.js, WebRTC, PWA, published notater & notater-cli on npm.
