**Wingfoil: Stream-Oriented Programming for Latency-Critical Systems**

Wingfoil is a blazingly fast, highly scalable stream processing framework designed for ultra-low-latency use cases such as electronic trading and real-time AI. Embracing stream-oriented programming makes it simple to receive, process, and distribute streaming data. This talk will explore where stream-oriented techniques are most effective and demonstrate how Wingfoil can be leveraged to build robust, high-performance systems.

**Building AI Copilots in Rust with Rig**

AI copilots are reshaping how we interact with software—but what makes them really work under the hood? In this talk, we unpack the design patterns and architectural choices that go into building a reliable copilot, then show how Rust and Rig make it practical to implement. From streaming responses to modular agents, we'll cover the key techniques while demystifying systems that enhance and power many developers' workflows.

**A deep dive into Ethereum and the Reth Ethereum client.**

Blockchain networks are built from multiple clients that communicate via a peer-to-peer (P2P) network. For a long time, the Go Ethereum client (Geth) has been the dominant force in blockchain. However, the Rust Ethereum client (Reth) is a significant challenger, being faster and more compact than the Go equivalent, costing less to run and able to handle breakneck execution speeds.
Rust brings modularity and high performance to Ethereum. With Geth, it is necessary to fork the repo, but with Reth, you can add components such as consensus whilst using Reth as a library.

**REDscript - building a compiler and language tooling in Rust**

My journey in reverse engineering the Cyberpunk 2077 game engine culminated in the creation of a new programming language and a comprehensive development toolchain, which included a compiler, decompiler, and additional tools.
