Senior🎓
Top SchoolMikhail Wall is a senior blockchain and backend engineer with 11 years of experience building high-throughput, production-grade systems across L2 scaling, MEV, and DeFi. He’s shipped core infrastructure for Polygon zkEVM—designing the sequencer, aggregator, and tx pool from scratch—and led protocol work at Primev on a P2P MEV pre-confirmation network and encrypted bidding to prevent frontrunning. At Infrared he built resilient on-chain keepers, a Safe multisig client, RPC failover, and OTEL-backed market surveillance for a top liquid staking protocol, demonstrating end-to-end product-to-protocol ownership. Previously he drove DEX execution and gasless intent settlement for a $5B+ hybrid trading platform and ran an enterprise blockchain handling up to 10M tx/day for Russian Railways. Comfortable in Go, Solidity and Rust, he pairs cryptographic prototyping (ZK commitments, sigma protocols) with pragmatic infra engineering. Based in Belgrade, he’s also an active OSS contributor to Polygon’s zkevm-node and exchange integration tooling, blending protocol research with production-grade code.

Contributions summary:Mikhail primarily created Data Transfer Object (DTO) classes for market data and trade-related functionality within the `knowm/xchange` repository, which provides a Java library for interacting with cryptocurrency exchanges. This work involved defining classes with properties representing various market data points like prices, volumes, and timestamps, and trade history details, for the DSX exchange. The user's commits demonstrate the user's focus on creating data structures to represent and handle market data from a specific exchange (DSX), indicating a back-end development focus on integration with the exchange's API. These classes are likely integral to the exchange's data processing.
