Solana Developer Needed – Pump.fun Style Platform (Starter Code Available)
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

Develop and execute user growth strategy end-to-end
Drive measurable increases in active users and platform volume
Build acquisition funnels (organic + partnership-driven)
Optimize onboarding flows and activation metrics
Lead social presence across Twitter/X and other platforms
Represent the project in Twitter Spaces and relevant community events
Launch and manage growth campaigns, incentives, and referral programs
Track and report on growth KPIs (CAC, activation rate, retention, volume impact)
Must-Have Experience
Proven track record of growing users and/or trading/activity volume in a startup, Web3, fintech, or SaaS environment
Demonstrated ability to turn social presence into measurable growth
Experience hosting or speaking in Twitter Spaces and similar forums
