About

Cloud-native integration engineer (Oracle/OCI) with strong production deployment and incident-response experience, including API gateway rollouts, observability (Prometheus/Grafana), and multi-layer debugging for payments systems. Built Python/FastAPI microservices and automation for customer-specific reporting and data sync, and has delivered major performance gains (45 min to <10) plus reliability improvements (MTTD reduced 40%+) through monitoring, playbooks, and resilient integration patterns (streaming/queuing, retries, secure tokens, VPC peering).

Key Strengths

• Led production API gateway rollout with rapid rollback and introduced API versioning to maintain backward compatibility
• Implemented contract tests, automated regression checks, and canary deployments to prevent schema-breaking releases
• Systematic multi-layer debugging using logs/metrics correlation; resolved intermittent payments failures tied to load balancer health checks
• Built synthetic monitoring and unified observability (Prometheus/Grafana) and tuned alerting; reduced MTTD by over 40%
• Refactored Python data-processing service using profiling + async I/O (aiohttp) and batching; cut runtime from 45 minutes to under 10
• Strong customer/operator collaboration: workflow mapping, added retries/backoff and operational dashboards with iterative demos
• Designed fault-tolerant on-prem to OCI integrations using normalization layers, streaming/queuing, and secure networking (VPC peering)
