Help Hope Live

I've spent the past three years modernizing Help Hope Live, a national non-profit in the medical fundraising space. The work has rebuilt their public website, admin portal, client portals, payment gateway, and accounting and finance systems on a Django REST API and an AWS Fargate cluster — designed for scale, fault tolerance, and the realities of a live operations team I work alongside throughout the migration.

  • Rewrote system architecture of public website, admin port, client portals, payment gateway, accounting & finance
  • Python, Django, React, Stripe, AWS
  • On-demand support for day-to-day operations

I worked for two years with Keolis as a backend lead on their new Transportation Resource Management System. The project focused on building reliable backend services for transportation operations, with heavy use of Django, test-driven development, and REST API design. I also managed a small team of one to two developers, helping guide implementation details, code quality, and delivery across the backend system.

Stylemetrics

I worked on beta versions of an AI-driven marketing research tool for a multinational clothing brand supplier, presenting the product direction and insights workflows to the CEO and key stakeholders. The platform analyzed financial and inventory data across international market segments, used custom Google Gemini LLM workflows and RAG engine processes to surface marketing insights, and integrated with Shopify and Google Cloud services.

Raddl logo

Raddl Reviews

I built the customer and admin React portals for Raddl, a membership review marketplace where shoppers earn wholesale pricing in exchange for honest product reviews. The system connects a WordPress/WooCommerce storefront, a Django REST API, and two React single-page apps — one for members submitting and managing reviews, and one for admins managing products, invitations, and review moderation. WordPress acts as the authentication proxy for the member experience, while Django handles admin auth, token-based invite emails, review submission, and review status workflows on top of Postgres, deployed via AWS Fargate and S3.

  • Built two React SPAs: a member portal for reviews and an admin portal for product and review management
  • Django REST Framework backend on Postgres with token-based invite flow and review moderation
  • WordPress/WooCommerce integration as the member authentication proxy and product source
  • Containerized with Docker, deployed to AWS Fargate and S3 with CircleCI CI/CD
NYU

NYU Scan & Reserve

I led a team building features for NYU Scan & Reserve, a student check-in mobile application used during COVID to track student traffic and reserve public spaces with QR code support. I served as release manager for both the iOS and Android applications, coordinating React Native builds and store releases across the team.

  • Led feature development for a student check-in and space reservation app during COVID
  • QR code-driven check-in flow for tracking student traffic and reserving public spaces

Hype Agency

I worked fullstack on a modern talent and event management platform for Hype Agency, building a single-page Elm frontend against an Elixir/Phoenix backend with a GraphQL API. The system supported talent profiles, job and event management, file uploads to Google Cloud Storage, location-aware features, CSV import pipelines, and transactional email — all sitting on top of Postgres with Guardian-based authentication.

  • Fullstack Elixir, Phoenix, and Elm across a talent and event management platform
  • GraphQL API with Absinthe, Postgres/Ecto, and Guardian authentication
  • Google Cloud Storage uploads, Google Maps geolocation, and CSV import workflows
  • Modern functional architecture across both frontend and backend

The work centered on creating a maintainable editorial platform that could support destination marketing, event promotion, and ongoing content operations.

  • Led Drupal implementation for a public-facing events and destination website
  • Built CMS structures for event promotion and editorial workflows
  • Coordinated technical delivery around content-heavy requirements

The system supported structured submissions, review processes, and scoring tools for evaluating student projects across the competition lifecycle.

  • Competition platform for international student submissions

John Hancock logo

John Hancock

I maintained a financial retirement calculator application for John Hancock, built in Angular and TypeScript, used by employees to model retirement scenarios and enroll in their company's retirement program against John Hancock's Signature fund selection. The work focused on keeping a regulated, financial-grade user experience reliable and accurate — covering form validation, masked input, session timeout handling, and a content/configuration model that supported maintenance and demo environments.

Florida Water Monitor dashboard preview

Florida Water Monitor

A personal project that pulls real-time water intelligence for Florida from three public datasets — USGS gauge stations, the U.S. Drought Monitor, and EPA's Safe Drinking Water Information System — and renders them as a single operational dashboard. The app tracks 200+ statewide stations with rolling 24-hour readings, breaks down drought class by county, and surfaces per-station trends alongside USGS data-quality flags.

  • Real-time Florida water dashboard pulling from USGS, USDM, and EPA SDWIS
  • Per-station trend analysis with provisional/approved data quality from USGS
  • County-level drought breakdowns and statewide drought-load summaries
  • Built as a Next.js app on seojeek infrastructure
