Staff Infrastructure Engineer | Tech Lead

2016 - 2024
  • Refactored the existing infrastructure automation to support the deployment of various environments on non-overlapping CIDR ranges. This allowed me to create a unified VPN experience for all Toast employees.
  • Migrated the configuration management code from Ansible 1.9 to 2+ and built a test suite to verify end-to-end functionality.
  • Created Apache Spark infrastructure for long-term reporting and analytical workloads, providing enhanced stability and performance for customers migrating from an existing transactional PostgreSQL database.
  • Played a key role as a 1st responder in all major service incidents and evangelizer for reliability engineering best practices.
  • Built a PCI egress control as a service solution on top of the existing cloud platform, bringing deep observability and metrics for each microservice for our service teams and SOC.

Infrastructure Building Blocks at Saylent

Saylent, later acquired by MeridianLink, was a technology company building a new fintech analysis product. Their developers had multiple software artifacts, but they needed a way to start deploying it into the cloud. Still, it didn't make sense for them to hire an infrastructure engineer full-time.

I built a lightweight deployment automation, continuous delivery pipelines, and infrastructure tooling that was low-maintenance, easily understood, and gave their team a good place to start.

This improved their ability to set up new customer environments, provide demos, and get faster feedback on their work.

Reducing the Cost of Downtime

At Puresend, the deployment of their core application code was done once a month due to the impacts of downtime. During the downtime period, marketing links that had been sent out would not function and would result in a request timeout error.

By implementing a failover application that could handle this traffic and record the metrics for later consumption, we were able to reduce the cost of downtime and set up a roadmap for improving developer velocity without damaging the business.

Scaling WordPress for Broadcast Television

A well-known television talk show had a WordPress-powered website that was going offline during their live broadcast, where they often featured promotions and other consumer engagement opportunities. This was costing their business revenue and was a common point of frustration for those watching the show and following along via social media.

I worked alongside a small team that identified performance issues in the website and helped bridge the gap between their internal team's understanding of the software project and their cloud providers. We solved technical challenges such as N+1 queries, migrated them to AWS, and provided a reliable and predictable means to scale up cloud resources during the live broadcast since auto-scaling wouldn't react fast enough.

We ultimately improved their website to a point where it could handle the live broadcast traffic without sweat and still save on hosting costs when they were off the air.
