HR platform APIs

REST APIs for employee records, time tracking, benefits and reporting, with versioning, pagination and auth. Legacy pieces split into services, with p95 times cut by about 40% on key workflows.

Case study

  1. 01

    The challenge

    Employee records, time, benefits and reporting lived in a monolith that teams could not ship independently, and key workflows were slow at the tail.

  2. 02

    The approach

    I designed versioned REST APIs with pagination and authentication, and split legacy pieces into services. SQL tuning, Redis and background jobs took the hot paths off the request. The services run on AWS.

  3. 03

    The outcome

    Teams deploy their own services, and p95 on the key workflows dropped by about 40%.

What shipped

  • Versioned REST APIs
  • Pagination and auth
  • Service split from the monolith
