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.
