Serverless Developer in Los Angeles, CA, United States

A SaaS product that enables small businesses to publish a professionally designed SEO-optimized website within 15 minutes.

I was the chief architect for this product and supported back-end development efforts. The solution was based upon storing content management data in Yellow's unified management platform, which was used to build and publish static customer websites built using GatsbyJS, React, and Tailwind CSS and served via CloudFront and S3. The platform also supported custom domain hosting, which was implemented using Traefik TLS proxies integrated with Let's Encrypt to provide fully automated certificate management/TLS support.

The core management platform included an AppSync GraphQL API, AWS Lambda functions written in Python, Step Functions for orchestrating workflows such as registering and updating site maps in Google Search Console, and an analytics pipeline implemented using AWS Glue to extract Google Analytics insights and create insights and reports in Yellow's unified management platform.

A one-stop shop where New Zealand businesses can find all the digital marketing products and tools they need to get online, get found, and get more customers quickly.

I was the brainchild and chief architect of the website, self-service portal, and underlying digital platform built on top of an AWS serverless architecture that integrates with Stripe for payments and subscription management and HubSpot for customer service. The platform enables customers to purchase digital products such as managing your business locations in Google My Business, creating digital marketing campaigns using Google Ads, and getting your own website with optional Shopify eCommerce integration up and running within 15 minutes.

A subscriber management and session management platform supporting 2,000 free and paid Wi-Fi HotSpots for Spark NZ.

I was the architect and lead full-stack developer for the project, which included a React-based captive portal for authenticating access using SMS and offering paid offerings using Stripe as a payment provider.

The back-end services were integrated with Cisco routers and FreeRADIUS servers, providing subscriber management (e.g., registration and login) and session management (e.g., device authentication and bandwidth metering) APIs servicing over 200,000 customers per month and connecting hundreds of thousands of devices every day.

The back-end architecture was implemented in Java using a microservices approach based upon the Vert.x framework and used VoltDB as a real-time in-memory database supporting up to 50,000 transactions per second.
