Howdy!

An ikigai is where your passion, career path, talents, and ability to provide value meet.

Programming is my ikigai. That's why I always seek to learned and grow to better provide value with code.


About Me

I'm Charles Pustejovsky.

Some things you're good at. Some things are good for you. For me, programming is both.

That's why I love programming and why I always seek to provide value with it.

It's why I love Go, Test-Driven Development, and SDLC methodologies (Agile/Scrum/Kanban).

They are all tools that help me provide value to my team and help the software we write provide value to users.

Projects

Here is a growing list of projects I'm working on or have worked on in the past (click to close)

Estuary

React/TypeScript, Go, PostgreSQL

During Thanksgiving weekend 2019, I started reading Getting Things Done by David Allen and had the idea to turn Estuary into a MERN app that could facilitate the GTD process.

That would have the dual benefit of cementing these practices for me and also building a robust app that I can proudly show off in my portfolio.

I'm currently rebuilding the client in TypeScript, the server in Go, and the database in PostgreSQL.

Twitter Bot

Go

My first Go application, this Twitter bot gives me less reasons to check Twitter by sending me updates from people I want to keep up with.

Since then, with the help of the amazing people on the Gophers Slack Channel, I was able to refactor it to better use Go's concurrency primitives (goroutines and channels).

CS:GO (Custom Sort: Go)

Go

Frustrated with some whiteboard interviews I encountered, I decided to start making a repo to collect code that sorts, reverses, etc.

This allowed me to learn how to set up benchmark tests to see which reversal algorithm was faster.

Also, trying to set up a generic sorting function, unsurprisingly, gave me an appreciation for Go's upcoming inclusion of Generics.

Life Together Calculator

React/TypeScript

The first application I created which calculated how long my wife and I had known each other and showed what percentage of our lives that was. It gave me hands on experience with working with the DOM and JavaScript's Date Object.

I then made it interactive so anyone with a significant other can calculate their life together.

Most recently, I've rebuilt the app in React and allowed it to calculate any kind of friendship or personal relationship.

BitPay Headless CMS

Nuxt.js / Vue.js

I used Ghost's Content API to turn BitPay's blog into a headless CMS and add the blog to BitPay's Nuxt.js site.

This created design consistency and allowed non-developers to make basic copy edits to BitPay's site without a full development process.


GDPR Toggler

jQuery

Love it or hate it, GDPR is a reality for businesses so I created a jQuery script to dynamically display an opt-in option for countries where that option was required (I used this AJAX script to determine the country by IP address). This was my first real taste of working with jQuery. The scripts would need customization for the countries and for the specific assets that are being displayed or hidden.

Dyno Waker

NodeJS

I created this to keep two of my Heroku dynos active from 6am to 9pm EST. I realized it might be useful for others who have a paid dyno and some free dynos, so I published it as a NPM module.

BitPay Blog Redesign

CSS/SASS

I forked Ghost's Casper theme and modified it with the help of an amazing marketing designer to give it a modern look.

Reading List


The Go Programming Language

I'm going through this book and will be finishing it around the end of Hacktoberfest.

Brian Kernighan has already written [one classic programming book](https://www.amazon.com/Programming-Language-2nd-Brian-Kernighan/dp/0131103628), so I believe I'm in good hands

Recurring Reading

The Pragmatic Programmer

This book is filled with wisdom and best practices that any programmer can use to improve their craft and better provide value with the software they help create. Now that I've finished reading it, I'm slowly going back throught it to really grok its lessons.

The Alphabetical Sayings of the Desert Fathers

The Desert Fathers of Christianity hold a special place in my heart. Their lessons of self-discipline, humility, perserverance, and not judging others help me not only as a developer, but as a human being. It is why I read some of their sayings at the beginning of each day, to center and focus me for the day ahead, with all the challenges it may bring.

Books I've Read

Concurrency in Go

Go is my favorite language for many reasons, but chief is how it handles concurrency. Given that, I thought it wise to dive deeper into that.

Katherine Cox-Buday has written an amazing introduction into Go's concurrency primitives (goroutines and channels), libraries (sync and context), and best practices.

This is definitely a book I'll be rereading in the future.

Check it out on O'Reilly Media


Let's Go

This book is absolutely wonderful for any newcomer to Go wanting to dive into web development.

Alex Edwards shows you how to build scalable, composable, maintainable backends with Go.

Learn Go with tests

I believe both Golang and TDD are excelent tools for writing scalable, maintainable code so it made sense to improve my Golang skills while also getting into the habit of doing test-driven development.

Learn Go with tests

I've never been at company that used Agile/Scrum and, as a result, have been able to see first-hand the issues that can arise from not following a system like this.

Jeff Sutherland does not only an amazing job of explaining the "what" and "how" of Scrum, but also the "why". Through anecdotes and philosophical asides, he lays a foundation for why Scrum can and will help any team be more effective.

It's very easy to read and is almost certainly worth reading multiple times. There are short summaries at the end of each chapter and an appendix for someone looking to implement Scrum for their team. It's an excellent book that anyone, but especially those working as developers, product managers, and project managers, should read.

Grokking Algorithms

I love learning about computer science both because it's fun and to fill in the gaps that I likely have from not getting a computer science degree. Grokking Algorithms by Aditya Y. Bhargava was a great place to start that journey.

Getting Things Done

I really love the system David Allen lays out in Getting Things Done. This system is what I am basing my productivity app Estuary around.
