Summary
🤩
Rockstar🎓
Top SchoolAkos Farkas is a versatile software engineer with 13+ years building data-driven analytical systems and blockchain infrastructure, spanning the full stack from databases to user interfaces. He has shifted from finance and retail analytics into cutting-edge consensus and VM work, contributing to well-known open-source projects like Filecoin and zkSync Era where he refactored consensus logic and improved core VM/gas behaviour. Comfortable in many languages (Python, Scala, Rust, C#, F#) and platforms (Spark, Kafka, Docker, AWS), he combines implementation skill with business analysis—bolstered by a MSc in banking to deepen his domain expertise. Akos repeatedly lands in roles that require both research-level thinking and production-grade delivery, such as integrating consensus protocols and re-architecting storage and memory behaviour for blockchain VMs. He gravitates toward problems with a scientific twist and often bridges teams by turning ambiguous requirements into robust, testable systems. Based in Tameside, England, he currently focuses on zero-knowledge and privacy-preserving tech while joining Aztec as a Noir generalist.

zkSync era
Role in this project:Back-end Developer
Back-end DeveloperContributions:89 reviews, 15 PRs, 90 pushes in 2 months
Contributions summary:Akos primarily refactored and implemented changes related to the consensus mechanism within the zkSync Era project. Their work involved renaming consensus tasks, splitting storage modules for better organization, and adding functionality for handling L1 batch quorum certificates. The user's contributions also extended to implementing methods for persistent batch storage, specifically related to L1 batch signing and attestation processes. These changes directly impact the core functionality and reliability of the consensus layer.
