A multifaceted, versatile, senior data/ML/software development engineer, computer scientist, mathematician, poet, writer, and lover of cats.
Greetings and felicitations! I'm William Fletcher Gilreath (he/him/his)
I am a multifaceted data scientist, senior machine learning/software engineer, computer scientist,
mathematician, poet, writer, and love cats.
I love working with software developing, testing, writing, and analyzing source code. In my spare
time, I write both code and technical articles, and narrative prose: novels, short stories, book
chapters, and poetry.
This home site illustrates some of the algorithms, code, programming languages, research papers, and
projects I have created, written, and published.
I am now as of May 2025 a data engineer (mix of computer
science+data science+software engineer) with Bayer. So...please
bayer with me 😜 ( very punny...) 🤪 as my career
takes a new trajectory.
For the curious and intrigued, an icebreaker question I often get asked is: "How did you get started
in software engineering?" I am more of a writer, so for this frequent question I have written a
five-minute reading time short article describing my path in
software/computer science/coding since I was a young boy.
Yet other questions I am asked are "What is the most difficult technical problem you had in your
career?" and "What is a time when you were wrong?" Both these questions are answered with this short
essay about an experience
I had early on in my career as a software engineer.
Get-Star (get)* is a
technical project I created, developed, and deployed that is a web search app. The project was a fun
mix of creating a website with a custom domain, and using HTML/CSS/JavaScript to create a useful web
tool for more efficient search.
The name "GetStar" is a homage to the 1970s movie Dark
Star" and the use of forty-two (another homage to Douglas Adams The Hitchhiker's Guide to the Galaxy" novel, the
answer to the great question...) parallel HTTP getrequests.
The Get-Star web app searches different sites and search engines with a search query but locally in
the web browser. This requires pop-up windows so that each searched website appears with any
results. Hence, this is not a super-search
engine, but a parallel, in-tandem search of heterogenous sites for different content, all
different.
A technical whitepaper "Get Star: The Problem of Finding Information across Multiple Web
Sites" [pdf (506 Kb) ] goes more in
depth, and is available on the get-star.org website.
My current technical project is a new programming language "ZeptoN"
from "zepto" + "N". A small programming language (zepto- is a factor of 10-21) that is
the Nth programming language (as programming languages go from 1 to N) where this is the Nth
programming language.
The ZeptoN whitepaper [ epub
| pdf (6 Mb) ]
describes the ZeptoN language, its goals, and gives many examples with output to illustrate the
ZeptoN programming language.
ZeptoN extends Java by adding a program entity "prog" construct like a class (without the
object-oriented trimmings), with an implicit program entry point as a block. Yet
ZeptoN is completely Java syntax and concept compatible. ZeptoN puts the program back into Java
programming!
ZeptoN is now available on my GitHub
repo for download, or the GitHub
page. This is the ZeptoN "Echo" transcompiler which transpiles to Java, and then uses the Java
Compiler API to build a Java bytecode .class file.
I have had an article about ZeptoN
published on JavaCodeGeeks explaining how to extend the ZeptoN language.
There are three articles on HackerNoon that
introduces, setup, and provides a "taste" of the ZeptoN language. These articles are:
Part 1: "What the Do-While Is ZeptoN?"
Part 2: "What the Do-While Is ZeptoN? Part II: Getting Started...What You Need"
Part 3: "What the Do-While is ZeptoN? Part III: A Taste of ZeptoN..."
More articles about the ZeptoN programming language will be written for greater examination, evaluation, and illumination of concepts, ideas, and other notions.
I have an inactive blog about my technical dabbling and other things...entitled Much Ado About Nothing where I write about this, that, and the other, but not of late. Note that I am not on social media (except LinkedIn) too much melodrama, and I do not want my personal life on the Internet.
I do write an occasional treatise or essay about a particular theme or topic.
One essay I have recently written is Innovator's Beware that
describes the 25-years timeline after creating an 'impossible' algorithm that sorts in linear
time by hashing, yet all the skeptics never got the source code to see the hash sort algorithm in
action. Quod, quod, fiat.
Here are some of the technical books I have written...
Computer Architecture: A Minimalist Perspective - explores computer architecuture of a one-instruction set computer the ultimate minimal instruction set.
Computer Architecture: A Minimalist Perspective Exercise Solutions Manual - the exercise solutions manual for Computer Architecture: A Minimalist Perspective problem questions at the end of each chapter.

Zing This! - The book covers the origin, history, implementation, and software architecture of the Zing network utility. The reader will explore utilizing, operating, and the functionality of the Zing network utility that are examined and discussed in depth. Available on GitHub.
I am a writer, and I write narrative stories as books, or novels. The fun is in the writing of a story, and how the story unfolds, and comes together into a novel. My published novels are:
Final Deadline: Foul Play without a Clue- I wrote this novel in 2014 under the pen name of "Moses Carlton Kery" or "Mo C. Kery" (get it?)... The story is a parody and satire of the classic murder mystery, and has multiple endings like the Choose Your Own Adventure style books from the 1980s. Whodunit? Read the book...
You're One of Those!? - I wrote this novel in 2022 about being a believer in Jesus Christ, but also gay...as two close college-bound friends experience and realize in this novel. The power of the maxims of: "love wins" and "love is love" yet in narrative story about going from hate of "dislike of unlike" to acceptance of another. The hardest persons to accept as-is are often those that are closest to us. Life is too short for hate--there is enough of that in the world.
Both a novel and short story I wrote is available on two social storytelling platforms Inkitt and
Wattpad; and these original stories are freely available to get and read. 😉 These stories are:
A murder mystery short story I have written in 2018 published in 2024 (using the Toki Pona name
of "Wilelelawa") is "The One at the Eleventh Hour" which I have published on both Inkitt
and Wattpad for anyone to freely read.
A sci-fi thrill novel I have wrote in 2024 is Mindtease which I have published on both Inkitt and Wattpad for anyone to freely read.
Do get, read, think, comment, and share. Writing was the easy part, now to find readers... 😜
Here are some theoretical research papers I have written, and have been published.

I do this, as I believe in the cliché "the power is in the sharing..." and my goal is to promote
acceptance and understanding of neurodiversity.
