About
Full-stack engineer in an insurance + telematics org who built a 0→1 multi-agent, AI-driven mobile regression execution system integrating Jira and n8n, emphasizing determinism (schema-validated outputs), traceability (state-machine style step archives), and scalable device scheduling. Also designed an event-driven microservices architecture using Kafka with standardized API/event contracts and has hands-on incident response experience improving resilience via rate limiting, circuit breaking, caching, and idempotency.

Key Strengths
- Built 0→1 multi-agent AI automation platform for mobile regression testing
- Improved test development/execution cycle by ~50% (reported estimate)
- Designed deterministic multi-agent workflows via single-responsibility agents + schema-validated structured outputs
- Implemented strong state-machine style step archiving/traceability to reduce run-to-run inconsistency
- Scaled execution with job queue + device lease model to prevent device contention under concurrency
- Production reliability response: mitigated traffic spike from buggy client via targeted blocking, then added rate limiting, circuit breaking, caching, idempotency and queue/timeouts
- Architected high-throughput event-driven backend with clear service boundaries and Kafka message bus across domains
- Drove company-level API standards via cross-team alignment (MCP) and shared Kafka/event contracts to reduce integration friction
