Node.js • AWS • Docker • PostgreSQL • GitHub Actions

• Built and owned the backend implementation that aggregates CMS-driven content (e.g., comments, reading time, metadata) across microservices and exposes mobile-ready APIs for iOS and Android.
• Implemented a transformation microservice that mapped raw CMS payloads into the mobile team’s predefined schema, ensuring contract consistency and smooth client integration.
• Owned two production microservices end-to-end: (1) data retrieval from CMS systems and (2) payload transformation into app-consumable responses.
• Investigated and documented NYP’s custom CMS modules and internal packages, deep-diving into package code to clarify data flow and unblock delivery.
• Proposed and implemented improvements to the data processing pipeline after analyzing end-to-end flow, reducing response payload size by 10% and improving client-side efficiency.
• Worked within AWS + Docker environments and supported release reliability through CI/CD workflows using GitHub Actions.
• Participated in team-wide code reviews with a focus on performance and code consistency, helping maintain scalable and maintainable backend services.

• Improved Nike’s CMS publishing workflow by optimizing the localization/translation pipeline, reducing time from content creation to live publishing by 5%.
• Led development and ongoing maintenance of localization and translation features, ensuring consistent multi-language experiences across CMS content and UI.
• Delivered scalable front-end components using React, Material UI, and Nike’s internal UI component library, aligning UX with Nike design standards.
• Collaborated within a cross-functional team (2 backend, 2 frontend, lead, PM) to plan, build, and release localization enhancements in line with product priorities.
• Strengthened quality and maintainability through code reviews and standards, increasing consistency across localization implementations and reducing regressions.

React • React Native • Node.js • AWS • PostgreSQL

• Drove a major performance overhaul across the platform, rebuilding core services to significantly reduce end-to-end latency and improve responsiveness for patient/provider workflows.
• Optimized the PDF generation service for training specifications, cutting generation time from 6s to 2ms (~3000× faster, ~99.97% reduction) and improving downstream user experience.
• Shipped full-stack features across provider web (React) and patient mobile (React Native), delivering production-ready functionality backed by Node.js services and PostgreSQL on AWS.
• Supported a hybrid MSK care product (RTM + Home Exercise Programs), ensuring reliable delivery of care content and app experiences outside the clinic.

Node.js • Express • React • React Native • PostgreSQL • AWS • Material UI

• Led end-to-end delivery of a fitness/training application, coordinating a cross-functional team (2 FE, 1 BE, PM, PO) to launch a production-ready platform for an existing gym customer base.
• Enabled adoption for 1,000 existing gym clients, ensuring a smooth transition from legacy processes to the new web/mobile experience.
• Maintained 99% availability in production by prioritizing reliability, monitoring, and robust release practices across backend and client applications.
• Delivered core backend capabilities with Node.js/Express and PostgreSQL on AWS, ensuring secure, scalable data handling for user plans, sessions, and progress.
• Built and maintained user-facing experiences across React (web) and React Native (mobile), using Material UI to deliver consistent, responsive interfaces.
• Established delivery and engineering standards as team lead (planning, code reviews, technical direction), improving consistency and reducing rework across the team.
• Drove user value by shipping exercise video streaming, enabling members to follow guided workouts directly in the app.
• Built and maintained user management (authentication, profiles, roles/subscriptions) to support the gym’s 1,000 existing clients on a single platform.
• Implemented Stripe payments (checkout/subscriptions/webhooks) to support secure billing flows and reliable access control tied to payment status.
• Maintained 99% availability by designing for reliability across AWS-hosted services and production releases.

React.js • PayPal internal UI library • Internal CI/CD tooling

• Built and maintained the tenant onboarding experience for a B2B payments product, guiding new business tenants from initial setup to a ready-to-transact state.
• Implemented onboarding flows in React.js using PayPal’s internal UI component library, ensuring consistent, accessible, and compliant user experiences across products.
• Developed onboarding steps for key business setup needs, such as tenant creation, admin/user setup, billing configuration, and payment readiness (e.g., verification and required information capture).
• Coordinated closely with backend and product teams to align onboarding UX with payment-domain requirements (error handling, retries, and clear state progression).
• Supported releases through PayPal’s custom internal CI/CD application, following established rollout practices to safely deploy onboarding changes.
• Contributed to code reviews and shared standards to keep onboarding code consistent, maintainable, and scalable as tenant configurations expanded.

Node.js • React.js • Custom UI Library

• Modernized Flowhub’s cannabis retail platform by migrating key experiences from a legacy UI to a new UI system, improving consistency and long-term maintainability.
• Rebuilt operational workflows for register/cash drawer management (creating/managing drawers tied to registers/POS stations), making daily store operations smoother and less error-prone.
• Implemented and refined role-based access and permissions to ensure the right staff had the right capabilities during onboarding and day-to-day use.
• Delivered full-stack enhancements across React and Node.js, including backend changes needed to support updated UI flows and keep frontend/backend contracts aligned.
• Supported a compliance-focused workstream, validating that product behavior matched the regulatory-heavy nature of cannabis retail operations.
• Worked closely with a small cross-functional squad (FE, BE, QA, PM, PO) to ship changes safely and maintain quality during a large UI transition.

• Improved software performance by optimizing full stack code and implementing efficient algorithms.
• Facilitated effective communication between team members using various collaboration tools such as Git and Jira.
• Implemented best practices for coding standards and documentation, fostering a culture of excellence within the team.
• Contributed to the success of software projects by providing expert guidance during all phases of the development life cycle.
