A solo developer built WhaleTrack, a real-time whale tracker for Polymarket prediction markets, reaching 129+ users in days using vanilla JS + Vercel serverless. For tech leads: demonstrates product-market fit with minimal infrastructure overhead and organic virality; signals growing mainstream adoption of on-chain data platforms.
