My name is Jon and I'm a Software Engineer at Heroku (part of Salesforce). I work pretty heavily in Ruby, SQL, and AWS but I can make just about any programming language do whatever silly task is asked of me.
Take a look at some of the work I've done over the years.
- Ruby Deserves Better Math So I Build enumerable-stats
- Improving the Heroku Postgres Extension Experience (Heroku Blog)
- I knew when I met you that an adventure was going to happen.
- Fix Hiring and Train a New Generation
- Embrace Chaos. Day 1 in Unfamiliar Code.
- Intro to DevOps for the Uninitiated
- Maintenance, Operational Concerns, and Cost
- benchmark_requires - Find slow loading libraries in your Rails apps.
- bettis - A toy databases that mimics redis.
- enumerable-stats - Statistical Methods for Enumerable Collections
- tobias - Recomends memory settings for your Postgres database
- gladys - Benchmarks Postgres databases, for science!
Here are the results of a lot of optimization work I did while at LivingSocial in 2015 or so. This change resulted in better response times for our users and allowed us to lower our compute footprint for a critical content distribution service.
