PROJECTS

Fine-Tuned Opensource Language Model Chatbot
 * An ongoing iterative research project focused on fine-tuning LLMs utilizing a
   curated dataset of my own personal and academic writings with the goal to
   develop a chat AI reflective of my writing style and ideation patterns.
 * Leverages open-source frameworks (including Hugging Face's Transformers
   library) and advanced self-hosted, customized hardware setups, which aims to
   create an AI assistant that engages in contextually relevant conversations
   that is locally hosted and cost-effective.
 * Utilized PyTorch for implementing and training the language model, harnessing
   its capabilities for efficient computation and optimization.
 * Utilized Nvidia Titan RTX and Tesla P40 GPUs for accelerated training and
   inference, overcoming the challenges of using legacy Tesla GPUs with modern
   transformer-based models rather than the previously predominant Recurrent
   Neural Network (RNN) models. Transformers, a new architecture introduced in a
   2017 paper, gained significant traction with the release of OpenAI's GPT-3 in
   2020. The latest Tesla and Titan GPUs, released in 2018, predate this surge
   in transformer use. Transformers are revolutionary because they save
   considerable memory compared to RNN approaches, with minimal tradeoffs.
 * Given my iterative ongoing work in developing LLMs, I have become Highly
   proficient now in developing AI centered approaches in  software application
   solutions that utilize language models ability in managing problems
   classicaly referred as non-deterministic or of polynomial time complexity.
 * I integrated RESTful APIs for model inferencing, enabling seamless
   interaction with the chat AI via web applications and other platforms,
   including utilization of streamed api protocols. Chat with my AI on my
   portfolio site at https://linkedinliu.com. Note: chat is only available on
   desktop web browsers.
 * To read a full technical report on this project, visit
   https://zi-ping.com/synthethics, a detailed portfolio report of the project
   now that is has spanned a full year of progress and of staggering results in
   multiple facets concerning machine learning and theoreotical mathematics.

Implementing CD/CI with Github Actions for my open-source project: a React
Component that displays PDFs using Adobe's SDK
 * As a distinguished leader in development operations (see:
   https://ziping.org/accolades), I have always been captivated by this
   challenge and persistently aimed to improve upon existing practices within
   the dynamic and challenging field of operational excellence and in tandem
   development operations.
 * I successfully developed and currently maintain a functional CI/CD system for
   one of my most active open-source projects:
   https://zi-ping.com/projects/react-adobe-embed. This project uses React and
   Adobe's Embed API and seamlessly integrates PDFs into web applications as a
   custom React component, currently serving thousands of users each month.

Pin-Yin Annotator for Chinese (Mandarin) Characters Web Application
 * A complimentary online text editor designed with the capability to append pin
   yin as annotated text above Chinese characters. This tool was born out of my
   personal struggle to locate an annotator that was user-friendly and harnessed
   the power of the most recent web technologies This project utilizes React,
   Vite, as well as backend Node.js (RESTFUL API)..
 * This editor is still in development but is free to use at
   https://pinyin.ziping.org.

Customized Wordpress Plugin Utilizing React
 * I began creating custom wordpress plugins, but realized that there was no
   official support of utilizing front-end frameworks or TypeScript when
   developing a wordpress plugin, especially relevant when developing wordpress
   plugins that are intended be a customized block utilized within Wordpress'
   visual editor, also known as Gutenberg. Hence, I created a solution which
   integrates usage of React, as well as TypeScript, within a wordpress plugin.
 * It is viewable as a github template repository, thus can be easily used as a
   starting point for a new repository on github for any developer who wishes to
   utilize the workflow I have created. Checkout the github template at
   https://github.com/ZIPING-LIU-CORPORATION/liulock-reactable-synthethics-chatblock.
