⦁ Architected an Apollo GraphQL server with Node.js that aggregates Kubernetes cluster metrics into a single schema for clients to query without multiple API calls or slow over-fetching requests and remains flexible for future iterations.⦁ Leveraged NodeJS worker threads to run asynchronous processes in parallel to improve GraphQL query runtime and port-forward a prometheus server without blocking synchronous I/O functionality or the single-threaded event loop.⦁ Implemented React Hooks to manage state with minimal code and leverage the lifecycle methods of functional components to trigger conditional rendering of presentational component visualizations based on user input within sibling components.⦁ Configured Travis CI to execute unit & integration tests developed with Jest and Enzyme, streamlining the code review process while ensuring the integrity and performance of the codebase across iterations. • Built a custom Webpack to provide an agile dev environment by writing the configuration to utilize hot module reloading and harnessing minification to reduce the bundle size in production, improving speed and UX.⦁ Oversaw a team of engineers through an agile development process by facilitating architecture discussions, managing code integration, coaching individuals through technical challenges across the stack, and leading code reviews.⦁ Containerized full-stack React applications with Docker and deployed to Google Kubernetes Service and AWS Elastic Kubernetes Service to test ShipShape’s monitoring tools under different stress conditions and use cases on both providers.

⦁ Led a team of engineers within a Scaled Agile Framework (SAFe) to upgrade React web and native iOS apps, driving ~100,000 new accounts and a $1 billion increase in global card spend while maintaining international compliance.⦁ Oversaw the implementation of a NoSQL document store that saves 400+ engineering hours annually by removing code dependencies required to launch new campaigns and paving the way for a no-code self-serve GUI that will save even more hours.⦁ Reviewed RFCs and Jenkins test results with DevOps to ensure successful releases through a Blue-Green deployment model that eliminated downtime and defect risk on critical applications around the world used by millions daily.

⦁ Optimized Redux with Thunk middleware to abstract async fetch calls from components to keep them pure and declarative, keeping the code clean for improved maintainability and debugging.⦁ Utilized a NoSQL database to store conversation threads for fast read times and a flexible schema that supported rapid iteration and aggregation queries to display the correct language without storing duplicate message documents.⦁ Created unit and integration tests with Jest/Enzyme to ensure that the application met specifications and to prevent defects.

⦁ Integrated OAuth2 protocol for a direct authentication pattern that provided frictionless sessions managed by a third-party platform and access to user data for a seamless onboarding experience.⦁ Implemented an Express server to leverage the single-threaded event loop with a chained modularized middleware pattern to authenticate and sanitize HTTP requests before executing database & 3rd Party API queries.⦁ Utilized Atomic Component-Driven Development to give users unique profile configurations by positioning customizable widgets with CSS Grid and Flexbox based on React Router parameters used to pull page settings from a NoSQL database.

⦁ Created functional prototypes in Figma to coordinate engineers in iterating on our React/Node.js application.⦁ Groomed user stories and estimated engineering effort to prioritize our product backlog along the RICE scoring model backed by quantitative & qualitative data from Google Analytics, FullStory, user interviews, competitor analysis, and live tests.⦁ Managed the agile development process for a team of remote developers and designers.

⦁ Created a project management system that coordinated 60 people to publish and distribute content to over 3,000,000 monthly readers; scaling our business from ~$6,000 MRR to $150,000+ MRR in 18 months with clients from the Fortune 500 and Y Combinator.

⦁ Scripted tools with Python, PHP, SQL, and Regex to automate business operations and integrate custom data feeds for our customers.⦁ Oversaw front-end refactor to AngularJS that leveraged MVC architecture to create a responsive UI with real-time data editing and conditional rendering powered by an extended version of the existing API for backward compatibility.⦁ Wrote requirements for a PHP server that was capable of receiving and sending REST API requests via HTTP & FTP to support authentication and updating an ACID compliant SQL database, avoiding concurrency issues with eCommerce transactions.⦁ Wrote the documentation of our API and internal system design for both technical and non-technical audiences.• Developed a tiered defect triage system that maximized the use of engineering resources by prioritizing critical fixes in an efficient manner.• Established engineering paradigms and practices for the company with the VP of Engineering to keep code maintainable and consistent across different components and integrations.⦁ Created UI Wireframes and collaborated with designers & engineers to implement responsive design.⦁ Nurtured strategic partnerships with companies like Amazon, eBay, Etsy, and Alibaba and gained access to early versions of technical releases, internal documentation, developer support, and client referrals.⦁ Closed sales by serving as the technical liaison with engineers at client companies. ⦁ Interviewed and hired software engineers & QA analysts to scale the team as we grew from less than $10,000 ARR to over $1,200,000 ARR.
