Solana TypeScript Trading Bot Development

I’m looking for an experienced Solana / TypeScript developer to help build a real-time wallet analytics and automated trading platform. The system will use Helius to monitor Solana on-chain activity and identify, analyse and rank wallets based on historical and ongoing trading performance. The initial system should include: Real-time Solana transaction ingestion using Helius (WebSockets/webhooks/RPC) Automated wallet discovery and tracking Wallet performance profiling including win rate, P&L, profit factor, trade count, holding time and other metrics Configurable wallet and token filters Wallet scoring/ranking system Candidate / shadow-testing / challenger workflow Paper/shadow trading engine to forward-test wallet signals without real capital Realistic modelling of fees, slippage and execution latency PostgreSQL/Supabase database Real-time web dashboard showing wallet discovery and shadow performance Architecture capable of supporting automated Solana trade execution at a later stage Preferred stack: TypeScript / Node.js, Solana, Helius, PostgreSQL/Supabase, Next.js/React, Vercel. Experience with Jupiter, Solana DEX execution, RPC/WebSockets and automated trading systems would be highly desirable. I want to develop this in milestones. Phase 1 will focus on data ingestion, wallet discovery, wallet profiling and the dashboard. Live trading is not required initially. Please include examples of previous Solana/on-chain analytics/trading bot projects you have built and specifically mention any experience with Helius and Jupiter. Please also explain briefly how you would architect the wallet discovery and real-time data pipeline. Important: I am looking for someone with genuine Solana backend experience, not solely general web development or smart-contract experience.
