• Overview: PayPal Credit Platform team member, developing new-and-rapidly-growing high-traffic credit products.

• Accomplishments

⠀ ‣ Designed and delivered core acquisition, eligibility, product, and financing layers for a global Credit Platform; engineered high-availability components powering dozens of products, supporting millions of customers, and transacting billions in quarterly volume.

⠀ ‣ Pioneered and championed an internal integration testing platform that evolved from a personal side-project into an org-wide cornerstone showcased by executive leadership. The tool simplifies and abstracts complex domain interdependency by orchestrating 120+ RESTful API calls across 30+ domains via Slack, CLI, and its API, supporting 300+ developers’ manual testing needs and 20+ components’ automated integration test data setup.

⠀ ‣ Directed product expansions across multiple EU markets, US, Canada, and Australia; collaborating with legal and product stakeholders to translate regional requirements into technical roadmaps and driving engineering execution via team mentorship and oversight.

⠀ ‣ Architected a dual-write synchronization strategy to facilitate a zero-downtime core credit application database and schema migration. Simultaneously re-engineered the existing data access layer with optimized data structures and algorithms, reducing average HTTP latency by 25% (from 17ms to 12ms) and slashing P99 tail latency by 75% (from 1700ms to 400ms).

⠀ ‣ Coordinated across three companies to develop a PCI-compliant vaulting service crucial to the Venmo Credit Card, enabling PayPal to securely and idempotently tokenize card data via Braintree on Venmo’s behalf.

• Skills

⠀ ‣ Frameworks & APIs: Spring Boot, Spring JDBC, Hibernate ORM, GraphQL (GQL), OpenAPI, JAX-RS, CloudEvents, JSON Web Tokens (JWT)

⠀ ‣ Infrastructure & DevOps: Docker, Kubernetes, Jenkins, Terraform, Git, Windows Subsystem for Linux (WSL), Maven

• Solely built a full-stack, real-time park attendance system to ensure COVID-19 regulatory compliance essential for reopening.

• Overview: Software Engineer and Aquatics Manager after starting as a lifeguard

• Highlights: Many "homebrew" software projects such as register system, security system module, lifeguard scheduling/roster app, job application system; many graphics-design projects (signage, promotional videos); and of course, probably the most daunting--managing a staff of 300+ teenage lifeguards a season!
