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 [...]")

Non-bulletpoint feedback:

• Your skills section has bad grouping

  • Take out Methodologies altogether
  • AngularDart isn't really a language
  • REST is not a platform

• I would recommend keep Lanugages pure, and do a second BP for technologies, i.e

  • Languages: Java, Kotlin, Python, SQL, Swift, [JavaScript], TypeScript
  • Technologies: Docker, Firebase, Google Cloud, gRPC, REST, iOS, Android, Git, Gradle, Maven

• Usually people have one for Libraries/SDKs which could help too, since iOS and Android could be moved there (with their SDK equivalents) and it would show off more skills

• Take out courses

• Make your projects reverse chronological order

• Put your start and end date for Education

Bulletpoint feedback:

Build iOS App for Local Bar:

• Apart from Apple pay and Firebase DB (which one?), you did not mention any tech stack you used

• You spent way too much focus on the "Situation/Task" with virtually no focus on "Action" and zero focus on "Result"

  • I.e "• Worked in agile team: collected user stories, scheduled regular client meetings, held twice-weekly scrum stand-ups • Allowed customers to order drinks, earn reward points in loyalty program, and view calendar of upcoming events • Enabled owners to modify menu items and events for customers to see"
  • Should all be one line: "Developed iOS app for order menus, loyalty program and events using [SDK 1, SDK 2] for [client X] via agile methodology"

• Then add one more line talking about results, if you have any (how many customers used it/how much scale the app can handle/anything numeric is ideal)

Craigslist-style Freelancing Job Platform, Android App

• Same feedback as above. Include more tech details on what tools you used, and give numeric data on the impact (Results)

Charity Database

• Include what tools and languages you're using.
  • I.e. "Designed frontend console UI to display query results in dynamically sized tables"
  • Should be "Designed frontent console UI with Bootstrap5 and AngularDart, supporting 15+ query results and dynamically sized tables"

Peer-to-Peer File Sync App

• This line is good - It could be written a little better, but you explain Situation/Task, Action, and Results: "Created decentralized file synchronization network running in Docker containers, written in Java. Scaled up to 200 nodes"

Contributor to open-source video game project

• "Contributed features to video game project on GitHub called RuneJS" - Do I know you lol? I'm an ex-2009scape dev. Anyways, include how many features - numeric data pops out.
  • I.e. change to "Contributed 10+ features to Github emulation project RuneJS"
  • Combine "• Implemented a system to play music depending on character’s location in-game, keeping track of discovered music • Added Jukebox functionality allowing users to manually play discovered music tracks by name"
  • I.e. "Implemented music system supporting area based activation and manual play"

Some quick feedback -

Non-bulletpoint Feedback:

• Put your education way at the bottom, recruiters quickly scan top and bottom to see if you have a degree
• Take out your Strengths

Bulletpoint Feedback:

• Your bulletpoints have a good mix of Situation/Task, Action and Result, but they very rarely touch on more than one at a time. In general it seems like some of them should be condensed or combined.
• For projects, start bulletpoints with "Developed website for .." rather than "A website for ..."
• Tie how you used different techs into your bulletpoints
• Add numeric data to your bulletpoints to show off results

i.e. "Created Account Aggregation Service resulting in instant customer account verification and faster loan journey."

Should be "Redesigned Account Aggregation Service in Kotlin and MongoDB resulting in <1 second account verification and 50x faster loan journey"

i.e. "Enabled faster courier journey and enhanced security through integration of items with barcode scanners." - This is actually good because it has some Action, but it can be better

Change to "Enabled 4% faster courier journey and enhanced security through item barcode scanners via [xyz] and PostgresSQL"

i.e. "Refactored backend code achieving a 20 times increase in performance of DB queries." - This line is great

i.e. "* Improved user experience by fixing bugs which caused silent failure in customer journey. * Improved consistency and reliability of the system by fixing bugs which caused duplicacy of customer applications."

Change to "Improved user experience by fixing 50+ bugs in customer journey and application portal over a 12-month period"

i.e. "Extensively used XP practices of pair programming and TDD to deliver quality and value." - What metrics do you have to prove value?

Change to something like "Fostered culture of using XP practices of pair programming and TDD to reduce regressions by 30% over a 6 month period"
