A principal engineer at Just Eat Takeaway writes long-form technical articles on software architecture, authentication concepts, and iOS modular design. The excerpts offer reference-style explanations and detailed accounts of real engineering decisions from a large production system.

Jesus Guerra writes first-person engineering essays on seniority levels, debugging a slow XCUITest run caused by waiting on a web view process, and the limits of individual problem-solving as engineers grow. The posts blend personal reflection with concrete technical diagnosis.

William Boles writes about iOS development in Swift and Objective-C, focusing on software architecture and code organisation. Posts cover practical design patterns such as avoiding overgrown shared components, resisting over-engineered form abstractions, and structuring modular projects with test-helper targets.

A personal technical blog newsletter on iOS and macOS internals, covering reverse engineering, Mach-O binaries and Swift compile-time techniques. Readers get hands-on, tool-specific walkthroughs, including how AI tooling can be applied to development workflows.
