  • Experience developing RESTful APIs and backend integrations with solid understanding of API design, data flow, and security best practices.
  • Hands-on experience with databases (e.g., MySQL, PostgreSQL, MongoDB) and caching systems (e.g., Redis) for handling high-volume, low-latency queries.
  • Familiarity with search and indexing technologies (e.g., Elasticsearch, Atlas Search) and analytics tracking for engagement and conversion.
  • Comfortable using monitoring and debugging tools such as Lighthouse, Sentry, Web Vitals, or Grafana to ensure performance and stability.
