A real-time audience-engagement platform — live polls, word clouds, Q&A and quizzes the whole room joins from their phones, no app install. Next.js 16, Socket.IO over Redis, Postgres.
YouTube & HLS video downloads, browser-capture, and signed auto-updates for the macOS download manager.
Documenting how the download engine, actor concurrency, and AI agents actually get built — in public.

About Me
I'm a Full Stack AI Engineer building financial research AI agents — production systems that pull live market data, reason through financials, and generate analyst-grade reports, fully automated.
Currently at Spiral Kite Labs, I own the full stack: LangGraph agent architecture, LangChain tool integrations, FastAPI backend, Google Cloud Run infrastructure, and the React frontend that makes it usable.
When you're the AI + DevOps + backend + frontend person at a startup, you stop thinking in layers and start thinking in outcomes.

Flagship · Open source
A fast, multi-threaded download manager for macOS — chunked HTTP downloads, browser-extension capture, and YouTube/HLS video via bundled yt-dlp. SwiftUI + an actor-based engine.
Live audience engagement for talks, classes and events — polls, word clouds, Q&A and quizzes the room joins from a phone browser with a code, no app or account. Next.js modular monolith plus a separately-scaled Socket.IO + Redis realtime tier, load-tested at 1,000 simultaneous joins.
Run npx signalboy and walk your house watching the dBm move on a Game Boy-style LCD. Kalman filter settles the reading, EWMA keeps the sparkline live; zero dependencies, per-OS backends for macOS/Windows/Linux, plus a native Android app that reads the phone's own radio.
Recommendation
A word from someone I've built with.
I had the privilege of mentoring Suryansh, and I've been genuinely impressed by his technical expertise and problem-solving abilities. He's highly skilled in web development, with a strong grasp of Next.js, React.js, and JavaScript frameworks, and he has hands-on experience working with OpenAI technologies and AI/ML applications.
Suryansh approaches challenges with a clear, analytical mindset, consistently delivering thoughtful and effective solutions. His dedication to learning, coupled with his ability to share knowledge and collaborate, makes him a standout professional. I'm confident he'll excel in any role he takes on.
