December 2025: TLS Library Modernization and Dependency Transition in pubky-core focused on security hardening and cross-platform readiness. Implemented a modern TLS stack for Apple Darwin targets (aarch64/x86_64) by introducing OpenSSL as a cross-compilation dependency, followed by a migration to Rustls for TLS, and updated related dependencies to Rustls for security and performance improvements. The work lays groundwork for safer, faster secure communications across platforms and simplifies future maintenance.

In November 2025, delivered significant Docker and CI/CD improvements across pubky/pkarr and pubky/pubky-core that enhance deployment flexibility, reliability, and speed. Implemented multi-arch build capabilities, stabilized CI by removing unnecessary dependency updates, and simplified Docker builds by eliminating aarch64 cross-compilation. These changes reduce build failures, accelerate release cycles, and broaden deployment options for customers and downstream services.

Monthly summary for 2025-07: Delivered Cross-Architecture Docker Image Build Support (aarch64) for the pubky/pkarr repository, enabling ARM64 builds by updating the Dockerfile to use a newer Rust toolchain and conditionally installing cross-compilation tools. This work expands deployment options, improves CI reliability for multi-arch targets, and accelerates time-to-market for ARM-based environments.

Month: 2025-06 — Key feature delivered: Multi-arch Docker image support for pubky/pkarr. Implemented TARGETARCH build argument, conditional installation of ARM cross-compiler, selection of the correct Rust target during build, and copying the appropriate binary to enable building and distributing an aarch64 image. This expands platform support for ARM-based deployments and enhances CI/CD flexibility for cross-platform releases. Major bugs fixed: none reported this month. Overall impact: broadened deployment reach to ARM-based environments, faster time-to-market for ARM containers, and a more reliable multi-arch build pipeline. Technologies/skills demonstrated: Docker multi-arch strategies, cross-compilation workflows, conditional build logic, Rust target targeting, and ARM toolchain management.
