Full-Stack Developer Needed: Telegram Mini App (TMA) with Supabase & Paystack/Monnify Escrow Engine

We are building ThirdParty (3P), a highly specialized peer-to-peer (P2P) marketplace and reverse Request-for-Quote (RFP) engine built entirely as a Telegram Mini App (TMA) for the Nigerian market. The core value proposition is solving the low-trust barrier in local commerce using an automated escrow payment system and a volume-weighted merchant reputation engine. We need an expert full-stack developer (or small, agile agency) to build out our MVP. You must have deep experience working within the Telegram Webview ecosystem, securing relational databases, and integrating local Nigerian fintech payment processors.
