Health Enhancement Systems
March 2022 to present
- Lead development of a Rails 7 platform serving React and two native mobile clients. Build APIs and product features on the versioned, swappable-service architecture that replaced separate Rails 3 product forks.
- Designed a Godot-inspired scene system that compiles user and content state into data-driven trees for consistent rendering across clients and reuse across multiple wellness products.
- Reduced serialization time by up to 80% on large, deeply nested collections by replacing per-request object initialization with reusable class-level serializers.
- Resolved recurring database slowness by moving N+1-prone leaderboard queries to Redis and TTL-based device step-logging data to DynamoDB, alongside broader indexing and data-reduction fixes.
- Use CloudFormation to provision and connect AWS services for new products and isolated beta environments, and maintain CI/CD pipelines and application monitoring.
