During August 2025, work focused on expanding the Michaelkelly71/C_Programming repository with a suite of three C programs designed for educational and tooling purposes. The developer implemented a Caesar Cipher tool supporting user-defined encryption keys, a DNA complement generator for efficient sequence transformation, and a readability analyzer that estimates the U.S. grade level required to comprehend a given text. All programs were written in C, leveraging algorithm implementation and text processing skills to deliver clear, traceable solutions. The approach emphasized maintainability and practical utility, with well-documented commits reflecting a methodical workflow and attention to both usability and code clarity.
