ABOUT ME

Software Developer

I am a software developer, in the sense that I help bring software to life, whether it is through programming, testing, enabling continuous integration and deployment, documentation, or reaching congruence with other team members, teams, and client representatives. I love to make life easier for others by advocating for internal and external consumers, supporting the team with the best tools available, and enabling developers of all levels to excel in what they do.

I love to learn, and spend a good portion of my time outside of work learning new concepts and technologies in the field. I enjoy sleeping, volleyball, and watching e-sports in my spare time. I also write at blog.neverendingqs.com

Our company started moving from self-hosted to AWS-hosted a few years ago, and I was on one of the first projects to AWS. We first experimented with CloudFormation and Elastic Beanstalk, but with our transition to being a DevOps team (being responsible for development, deployment, and monitoring), we switched to a serverless architecture to reduce operation (dollar and time) costs.

I introduced myself to Node.js via a Udemy course, and have since used it and am still using it to develop and maintain a big data platform in a corporate setting. My experience has been mostly on back-end (Node.js, especially with AWS Lambda and the Serverless Framework), but I have developed some single-page applications (Angular and React) on the side.

Before transitioning to a serverless architecture, we leveraged Python 3.x.x and boto3 (AWS SDK) to deploy our product into AWS. I wrote a functional library on the side that mimics the likes of C# LINQ / Java streams / Apache Spark's RDD transformations, although I now find delight in list and dict comprehensions and the magic that is in slicing.

C# was one of the first languages I encountered (after Java), and I find it to be the most enjoyable compiled language to write to date (although deploying it is another story). Being in company where the main product is written in C#, I am quite comfortable with it.

I have worked with several SQL engines throughout my career, starting with SQL server while I was working on an analytics project (especially the data ETL process). I have since worked with PostgreSQL in code examples and MySQL via AWS Aurora.

pyiterable

Python comes with some nice built-in methods for operating on iterables, but it can get messy really quickly if you want to transform an iterable multiple times. Write more expressive code by chaining built-in transformations with this module.
