Announcing circle: a Haskell client for Circle's REST API(29 Nov 2022) Announcing my first Haskell package: circle! This package implements a Haskell client for Circle's REST API. It supports all V1 endpoints to let users create and manage accounts, wallets, and users; and send fiat and cryptocurrency between them. Hopefully this makes building a Haskell application that uses Circle's REST API much easier!

Data validation in Haskell with newtypes, smart constructors, and aeson(31 Oct 2022) I'm working on a library that is wrapping an HTTP API, and I'm heavily leveraging aeson for working with the JSON returned and sent to that API. This post describes how I implemented field validation on the type level using Haskell newtypes and hand-rolled ToJSON and FromJSON instances.

Reflections on my career in 2020(11 Jan 2021) 2020 felt like a particularly long year for a variety of reasons, and one of the reasons it felt long for me was because I changed companies twice after 5 years at Qualtrics! After starting the year there, I did a stint at 47 Degrees before joining Mercury at the start of December. Since this was the first time in my career that I'd actually changed companies, I wanted to write down some of my reflections on what I learned (both good and bad) throughout the process.

I drove into the sunrise today and it felt like hope(10 Dec 2020) Today I drove 12 hours from Seattle WA to Ogden, UT. This was a first for me. While I was no stranger to road trips, I'd never driven 12 hours straight before, and even though I had all day to do it, I was nervous that I wouldn't pull it off.

Implementing Dark Mode for my Website(04 Dec 2020) Now that both Windows and Mac have native dark modes for their respective operating systems, I figured I was overdue for enabling a dark mode on my personal website. Specifically, I wanted a site that inherited the dark mode settings from the user's operating system so that they didn't have to toggle in on the my website itself. Also, I wanted a solution that used pure CSS so that I didn't have to add any additional javascript to my site and modify any DOM elements at runtime. In this post, I cover how to configure dark mode based on your browser's OS, and how I went about picking CSS for dark mode that made sense for my page.

Building a Fantasy Football Draft Assistance Algorithm: Part Two(19 Nov 2020) Constructing a Fantasy Football draft assistance algorithm using Gaussian Kernel Density Estimation (Gaussian KDE) Part Two: Building the User Interface. Given my cross-sectional dataset from a variety of different fantasy football prediction sources, I implemented a DAsHA, a tool into which I could feed (a) the current draft position and (b) players already picked, and return as much data as possible for me to pick the best player that round.

Building a Fantasy Football Draft Assistance Algorithm: Part One(13 Nov 2020) Constructing a Fantasy Football draft assistance algorithm using Gaussian Kernel Density Estimation (Gaussian KDE) Part One: Collecting, Cleaning, and Preparing the Data. In order to beat my friends outperform the recommendations provided my fantasy football platform, I needed to create an cross-sectional dataset of projected player performance across a variety of different sources.

Getting Started in Open-Source(15 Oct 2020) As a software engineer at 47 Degrees, I'm ostensibly a member of the open-source community, since 47 Degrees spends a lot of time and resources on maintaining a few hundred libraries in Scala, Haskell, Kotlin, and Swift. However, unlike other folks at the company who were involved in open-source before they joined, I was never involved in a significant open-source project before joining.

My Note-Taking Process(03 Sep 2020) The other day I was asked about my approach towards packaging up my knowledge into a format that's worth sharing: 'My question to you is at what point do you package up what you have learnt to share with others? I’m a software dev and forming a habit of writing what I have done seems like it might distract me out of flow if i’m to take notes to share later when i’m working, consequently, I think i’m a little exhausted after coding to write something decent. That’s the little quagmire I find myself in at the moment, I wish to share, just don’t have the method. Any tips?' It was a great question, I figured it deserved an involved response, and when I finished writing my thoughts I'd written almost 500 words.

ValidatedNel in the Wild(24 Aug 2020) I'm keeping my streak alive and I wrote another blog post for 47 Degrees, this time a technical deep dive into a PR I made where I rewrote the error reporting in an sbt plugin to use error accumulation. There's a bunch of code examples that I cite from the blog post that guide the content.

47 Days at 47 Degrees(11 Aug 2020) I recently wrote a blog post for my new company about my initial impressions working there for the first month and a half. I ramble about several topics, including asynchronous working patterns, impostor syndrome, and the importance of seeking out work that's outside of my comfort zone.

macOS Catalina 10.15.4: Development Setup for my new Mac(06 Jun 2020) I bought a new personal laptop recently and I'm starting a new job soon, which means that I'm going to have a few new Mac laptops to set up in the near future. So, I figured it would be prudent to write my new Mac setup steps before I get the new computers and publish these steps somewhere so that I can easily get up and running with my new machine. My configurations isn't too crazy, but it is custom, and I think I have enough 3rd-party development and productivity tools installed that it's worth a blog post to cover all of the bases. On a final note, I'm primarily a backend/distributed-systems/data engineer, so my needs mostly revolve around Scala, Java, Go, Node, Python, and Haskell. YMMV!

Setting up a Functional Scala REPL with Ammonite(09 May 2020) One of my favorite tools in the Scala ecosystem is Li Haoyi's Ammonite, which is a tool that enable first-class scripting support in Scala. You can use Ammonite to run Scala code in the REPL, as scripts, or even as a system-level shell as a replacement to something like Bash. It's a great tool and one I use daily when writing Scala. My favorite thing to use it for is for advanced REPL support -- Scala is my favorite language and Ammonite lets me whip up little Scala scripts and run them in the command line as I used to do with Python or Node.
