Case Manager

Dynamic dashboards, N+1 bottlenecks removed, payments wired in.

Role
Full-stack engineer at Cybros.Dev — schema design and integrations

Overview

Built dynamic management dashboards backed by a database schema designed from scratch. Dashboards surface the query problems a schema is hiding, so a large part of the work was finding and resolving the N+1 bottlenecks behind the slow views, then integrating the third-party services the product billed through.

What I built

  1. Built dynamic management dashboards
  2. Designed the database schema end to end
  3. Resolved complex N+1 query bottlenecks
  4. Integrated Stripe and the QuickBooks API
