PROFILE
David Koski
Over four months, Daniel Koski developed and optimized machine learning infrastructure in the ml-explore/mlx-swift-examples repository, focusing on Swift and YAML for model configuration and CI/CD automation. He introduced a modular LoRA layer to enhance model adaptability and implemented configurable gradient control for flexible training. Daniel streamlined model configuration with Swift macros, improving serialization and concurrency safety, and refactored the ChatSession API for greater code consistency. He also optimized Llama model parameters to reduce resource usage and expanded CircleCI workflows to support multi-version Xcode testing. His work demonstrated depth in model optimization, build configuration, and maintainable Swift development practices.

May 1, 2025May 2025: Delivered three macro-driven features in mlx-swift-examples focusing on configuration safety, serialization consistency, and development workflow improvements. Key outcomes include a ReerCodable macro enabling default values and Sendable configurations (reducing boilerplate and enabling safe concurrent usage), adoption of Codable macro across model configurations for easier serialization, and build-time macro runtime along with CircleCI CI workflow enhancements to accelerate development and testing. Impact: safer, easier-to-initialize configurations, improved data encoding accuracy, and faster iteration cycles with a more robust CI process. Technologies demonstrated: Swift macros (ReerCodable, Codable macro), Sendable configurations, @Codable attribute, CircleCI.

Dec 1, 2024December 2024 — Delivered two core features in ml-explore/mlx-swift-examples: LoRA Layer Integration for Adaptive Modeling and Configurable Overridable noGrad for Training Flexibility. These changes establish a modular framework to wrap UnaryLayer with LoRA, adjust the attention path, and introduce overridable gradient control, enabling faster experimentation and more efficient training. No formal major bugs fixed were logged this month; groundwork was laid for improved stability and future optimizations. The work increases model adaptability, reduces training costs through weight/module consolidation, and improves evaluation workflows by enabling flexible gradient behavior. Technologies demonstrated include LoRA, Low-Rank Adaptations, training pipelines, and protocol/class design for extensibility.
