This is one of the best resumes we've seen as far - If you paid for the service, you'd probably get refunded

• Great organization, clickable links, organization of skills
• (Very minor) For your personal projects, if any of them have a repo, make them clickable

The general trend for your bulletpoints is they're very good. The only feedback I have is your bulletpoints have a lot of Situation/Task/Action, but no Result. They also lack a lot of numeric data that measures the impact. I've made up the numbers/results in my example changes, but fill them out with similar real ones per your work:

Cytracom:

I.e change "Maintained Cytracom’s centralized VoIP configuration API server and several dependent microservices in a breadth of languages, such as PHP, Typescript, Elixir/Erlang, and Scala."

To: "Maintained Cytracom's centralized VoIP configuration API server and 4 dependent microservices in PHP, Typescript, Elixir/Erlang, and Scala"

Change "Implemented major quality-assurance processes in longstanding codebases including code review, CI/CD, and smoke testing, and unit testing."

To "Implemented major quality-assurance processes in 2 longstanding codebases including code review, CI/CD, and smoke testing, and unit testing, resulting in a 95% decrease in regression bugs in prod"

Change "Debugged and refactored VoIP integration with an open source WebRTC server (Janus) to maintain better connectivity for our web phone users."

To "Debugged and refactored VoIP integration with open source WebRTC server Janus to maintain better connectivity for our 30,000 web phone users/month."

Juniper Networks:

Mostly same feedback, if you add quantification these bulletpoints will have a lot more impact. Also missing results.

Change "Architected and implemented major components of the configuration [...]"

To "Architected and implemented 5 major components including oauth and feature2 of the configuration [...]"

Change "Maintained substantial automated test suite for the functionality owned by a broad-reaching team"

To "Maintained an automated test suite with 30,000 tests for the functionality of a 55 million dollar product"

Change "Worked alongside field engineers to provide root-cause analyses for customer issues and prompt bug-fixes"

To "Worked with field engineers for root-cause analysis on customer issues, with the [shortest average incident response time of 1.5 hours/satisfaction rate of 90%/29 bug fixes in a 12-month period]

128 Technology:

Same feedback, add numeric data and results ("[...] through 17 different microservices leading to an average 90x speed-up for on-site debugging", "Added over 20 features and fixed 70+ bugs to company's [...]")
