Worked on the harvard-edge/cs249r_book repository to enhance installation reliability and tokenizer robustness, focusing on user-facing improvements. Addressed installation challenges on Ubuntu 20.04 by updating the install script to require Python 3.9 or higher, adding Git version checks, and clarifying setup requirements, which reduced install-time failures and improved onboarding consistency. Refactored tokenizer constants and improved vocabulary initialization to ensure consistent handling of unknown and end-of-word tokens, supporting more reliable natural language processing workflows. Utilized Python and shell scripting, along with version control and system administration skills, to deliver maintainable code changes that improved cross-environment reliability and developer guidance.
