carrier-facing services
• Integrated third-party REST APIs with error handling, retry logic, and logging to ensure stability under varying carrier
response patterns
• Optimised page load performance by profiling slow queries, reducing N+1 issues, and introducing caching with Redis for
frequently accessed data
• Worked with tables containing up to 1,000,000+ rows — applied indexing strategies and query optimisation to maintain
acceptable response times
• Participated in a microservices environment: implemented inter-service communication via REST and supported
