zk-SNARK Circuit Setup for Ethereum

I'm looking for an experienced blockchain developer to set up a zk-SNARK circuit on Ethereum. The primary purpose of this circuit is to enable zero-knowledge proofs for privacy, specifically for confidential transactions.

Key Requirements:
- Expertise in zk-SNARKs and zero-knowledge proofs
- Proficiency in Ethereum smart contract development
- Experience with cryptographic protocols and privacy-preserving technologies
- Ability to design and implement secure, efficient zk-SNARK circuits

Ideal Skills:
- Strong background in cryptography
- Familiarity with tools like ZoKrates or Snarky
- Previous experience with confidential transaction implementations

Please provide examples of relevant work and a breakdown of your approach.
