Top Token Trader crypto analytics visualizer
Top Token Trader D3.js / React / Alchemy API

Top Token Trader Visualizer

Client needed a developer to build an interactive crypto analytics tool that visualizes top ERC20 token traders across multiple chains. I created a Telegram Web App and web dashboard that displays real-time trading activity using an advanced D3.js bubble map, powered by live data from the Alchemy API. Users can explore wallet performance and token movements within custom time frames. The result was a fast, intuitive platform built for a crypto analytics challenge, giving traders clear insights into emerging market trends.

Matchlock peer-to-peer sports wagering on Solana
Matchlock Anchor / Go / React

Peer-to-peer sports wagering on Solana

Two people, one match, opposite outcomes. Escrow on-chain, settlement via CPI into TxLINE's oracle program. The winner pays the Solana fee to claim. Loser's funds go to the winner. No house, no spread, no funny business. Built for the Solana + TxLINE hackathon.

  • Anchor program (Rust) with escrow, CPI settlement, pause switch — funds never get trapped by admin action.
  • Go backend (Gin, GORM, Redis, solana-go) serving as keeper + API.
  • React 19 frontend (Vite 8, TypeScript 6, Tailwind 4, Base UI, Zod 4).
