🚀 Hiring Solana Developers – Pump.fun
Hi,
I’m reaching out from Valiant Solution LLC. We’re currently working with a U.S.-based client who is an experienced crypto professional and we’re looking for a skilled Solana developer to help build a platform similar to Pump.fun.
We already have a basic codebase from GitHub that the developer can start from, so the project will mainly involve customizing, improving, and completing the functionality rather than building everything from scratch.
Key requirements:
• Experience with Solana smart contracts (Rust / Anchor)
• Knowledge of token launch mechanics and bonding curves
• Experience with Solana Web3 integrations
• Ability to work with an existing codebase and extend it
If this sounds interesting, please reply with:
• Your Solana development experience
• Links to relevant projects or GitHub
• Your availability for a quick discussion
Looking forward to connecting.
Best regards,
Valiant Solution LLC
