Irfan Murad

Full-Stack Developer & AI Enthusiast building backend systems, full-stack applications, and AI-powered tools. Focused on shipping practical software that solves real problems.

Active in the Malaysian developer and Solana community. I care about clean architecture, structured workflows, and lean tooling.

When not coding, I'm journaling trades in Obsidian, tinkering with local AI models on a 4050, or looking for the next thing to automate.

Projects

echo-wallet-tracking
Automated Solana wallet discovery and scoring pipeline. Fetches on-chain data from Helius (Shyft failover), scores wallets on a 0-100 composite metric covering risk-adjusted returns, win rate, consistency, and activity health. Filters scam wallets via bundler and wash-trader detection. Exports ranked results to Axiom for copy-trading. Deployed on Railway with web dashboard, Telegram bot, and REST API.
sumsum-bot
Python-based trading bot for Polymarket. Uses NOAA forecast data to calculate an informational edge on weather contracts (temperature and precipitation). Trades fire only when derived probability exceeds market price by 10%+, sized with quarter-Kelly and capped at 5% per-trade exposure. Currently in paper trading with live execution gated behind a 2-week forward test.
superteam-telegram-bot
Telegram onboarding bot that gates group access behind member introductions. Admin tools for manual approvals, status lookups, and intro resets. Handles edge cases like rejoin tracking for ban evasion prevention. Built solo with TypeScript, Telegraf, and SQLite. Dockerized and deployed on Railway.
deriverse-dashboard-bounty
Full trading analytics dashboard built from scratch for a Solana perpetual DEX. 13+ interactive visualizations including drawdown charts, rolling Sharpe ratio, P&L distribution, and trade duration analysis using Recharts. Built with React 19, Zustand, shadcn/ui, Framer Motion, and URL-persisted filters. Realistic mock data generation for demo purposes.
