0 BIO
Hello! My name is Chris, and I am a Software Development Engineer on the Network Load Balancing Control Plane team at Amazon Web Services! As an SDE, I work to deliver features and system improvements to the NLB product! I graduated from Carnegie Mellon University with a dual degree in Information Systems and Civil & Environmental Engineering with a minor in Business Administration. In my free time, I am a tech consultant and founding member of Old Salt Coffee Company, which has been in operation since September 2020.
If I'm not in my office, you can find me at a rock climbing gym, on a hike, or at a local coffee shop working on various projects. I love the outdoors and try to get out as much as possible. That involves anything from snowboarding to scuba diving, and anywhere in between.
Currently, these are some of my daily languages:
- Java
- Python
- Ruby
- Liquid
- HTML & (S)CSS
- Javascript
- SQL

Software Engineer II @ AWS - Network Load Balancing (NLB) Control Plane Team
September 2023 - Present
- Adapted and zonally isolated the existing NLB deletion logic to mitigate risks during rollout while also expediting delivery in order to meet a critical customer deadline for a highly anticipated feature allowing users to remove availability zones from existing NLBs ultimately enabling customers to reduce their operational costs and overhead of maintaining unused resources.
- Transformed an existing beta feature’s design and was the team’s sole developer of an automated workflow for NLB on-demand capacity reservation, allowing enterprise customers to preemptively secure network bandwidth for high-traffic events. Worked closely with internal dependency services to iterate through the various constraints of handling large provisioning orders and escalated key design changes to product management to craft a viable customer experience ahead of the official launch at AWS Re:Invent conference 2024.
- Led the design and was the team’s sole implementer of AWS Route 53’s ARC Zonal Shift integration for NLBs, enabling seamless traffic redirection by availability zone—adopted by over 500K NLBs. Coordinated with five teams to deliver a rollout plan involving a backfill and migration of hundreds of thousands of users to an opt-in model with an automated monitoring and rollback system triggered in the event customer behavior regression was detected.
- Built a resource auditor which identified $1M ARR in leaked resources. Designed a cleanup mechanism to release unused resources while guaranteeing 100% safety to inflight production workflows.

Software Engineer I @ AWS - Network Load Balancing (NLB) Control Plane Team
April 2022 - September 2023
- Diagnosed and resolved issues in high-pressure, ambiguous situations - requiring advanced on-the-spot debugging and root-cause analysis –while also working to address systemic and noisy issues that previously generated 100+ weekly pages which now averages less than 35.
- Led the testing and enablement of 12 public-facing features and multiple internal service upgrades in government-isolated regions, ensuring compliance and code parity across all deployments while adhering to strict change management protocols.
- Organized and optimized the CI/CD pipeline for over 100 deployment stages across 20+ internal services, balancing rapid software delivery with safety by isolating complex environments and ensuring smooth rollouts.

MIXR - iOS APP
MIXR is an iOS app that is used for curating music for a group of music enthusiasts. If you have ever had difficulty selecting a Spotify playlist that everyone in your group agrees with, MIXR can help.
Our team created this app through the use of Spotify’s recommendation API to generate a playlist based on a group of users’ added tracks. Users also have the ability to export generated playlists to their Spotify account. Our team also utilized Firebase to store the user’s previously generated playlist data.
