HelloBubble β Building a Community Platform Solo
NYC startup / Remote from Israel / Nov 2025 β Mar 2026
The product: HelloBubble is a popular Gen Z cosmetics company. To drive word-of-mouth marketing, they built a dedicated platform for their brand ambassadors. Ambassadors receive social media challenges, submit their content for approval, earn points, and redeem them for cosmetic rewards, all while communicating via real-time chat.
My role: As the sole developer responsible for everything outside the mobile app itself, I designed and maintained the entire platform backend and management console for a system designed to serve 100K users.
The architecture: I built a React/TypeScript admin console and 11 Node.js microservices (100+ REST endpoints) deployed on AWS ECS Fargate via GitHub Actions (Blue/Green deployments). Infrastructure was fully codified using AWS CDK.
Key features: I engineered a gamification engine integrated with the Shopify API for the rewards storefront, a DynamoDB-backed runtime config system (allowing instant RBAC and feature flag changes without code deploys), and a real-time chat system using Sendbird, complete with an AI chatbot powered by Anthropic Claude.
