Solana/DeFi Developer for DEX MVP Fixes

We need a Solana/DeFi developer to make small fixes and adjustments to an existing simple AMM-style DEX MVP.

Scope is minimal and should fit a $20–$50 task:

Fix or adjust on-chain program logic (Anchor/Rust) for swaps or LP creation.

Correct SPL token handling issues (base/quote tokens).

Resolve small problems in liquidity pool creation or optimization of account usage.

Improve or patch simple AMM functions (add/remove liquidity, swap).

Fix small integration issues with Jupiter Aggregator (routing or API calls).

Correct minor UI bugs in the React/Vue front-end used for wallet connection, listing token pairs, adding/removing liquidity, or basic swaps.

Ensure fees/transactions are working properly and not failing.

Deliverables (small-scope only):

Fixes to on-chain code (no new features).

Adjusted front-end components.

Quick test to show swap and liquidity actions working.

Short notes about what was changed.

This is not a full DEX build — only bug fixing or patching the existing MVP.
