• Cut operator data-visibility delay by ~98% (30+ minutes to under 30 seconds) for 1000+ concurrent users, by redesigning the campaign pipeline in Java as a multi-threaded, per-key concurrent processor on a Redis-backed queue, improving performance and scalability. • Designed a pluggable multi-vendor telecalling layer in Java 17 / Spring Boot that sends 15 dialler operations (campaign launch, click-to-call, call-event webhooks) to the right one of 4 vendor adapters (SlashRTC, Cognifai, Ozonetel), choosing the vendor per user from Keycloak group membership. • Improved reliability and fault tolerance of outbound third-party webhook calls and prevented cascade failures during vendor outages, by implementing exponential-backoff retry with Resilience4j circuit breakers and transactional audit logging per API interaction for traceability, root-cause analysis, and production support. • Enabled bulk activity log uploads (CSV + ZIP, up to 500 rows / 200 MB) with no full in-memory load, by building streaming S3 ingest, async per-row image validation, partial-failure error reporting, and batch DB persistence; added a cleanup guard and configurable temp path to prevent disk quota breaches in containerised environments. • Reduced manual campaign management overhead by contributing to the AutoRechurn event-driven engine, which automatically advances dialer campaigns through configurable rechurn levels based on agent disposition codes. • Worked across the full SDLC in Agile/Scrum sprints: code reviews, Git, Maven builds, CI/CD (GitHub Actions), JUnit test coverage, and documentation. • Used AI coding tools (Claude AI, MCP connectors) daily for architecture planning and phased implementation.
