Senior Cloud & DevOps Engineer

Architected and automated scalable cloud environments using Terraform, Kubernetes (OKE), and OCI DevOps Service, supporting 8+ concurrent projects with 99% uptime across multi-region deployments. Led migration of legacy OpenStack workloads to AWS, utilizing EC2, EKS, RDS, S3, and Lambda to improve elasticity, reduce operational overhead by 40%, and enable global scalability. Designed and deployed Oracle Real Application Clusters (RAC) and Data Guard replication from scratch, implementing automated failover, performance tuning, and proactive alerting to handle critical errors and minimize downtime. Established comprehensive monitoring and alerting for Oracle replication groups using Prometheus, Grafana, and OCI Monitoring, reducing mean time to resolution (MTTR) by 30% through predictive anomaly detection. Optimized CI/CD pipelines with GitHub Actions and OCI DevOps, integrating security scanning, infrastructure validation, and staged rollouts to accelerate deployment frequency by 50%. Collaborated asynchronously with distributed EMEA teams to deliver secure, GDPR-compliant, high-availability solutions for enterprise clients in finance, healthcare, and the public sector.

Built private cloud infrastructure from scratch using OpenStack, TripleO, and Ansible, provisioning and managing 200+ compute and storage nodes across EU regions (Frankfurt, Dublin) with real-time capacity scaling. Implemented bare metal provisioning and lifecycle management using MaaS (Metal as a Service), reducing node onboarding time from days to hours and improving hardware utilization by 35%. Designed and operated robust observability stack with Prometheus, Grafana, ELK, and Datadog, establishing SLOs/SLIs and alerting policies that cut MTTR by 35% and improved proactive incident detection. Managed Oracle Database and PostgreSQL replication setups (Data Guard, logical replication) integrated with cloud-native backup and disaster recovery strategies to ensure GDPR-compliant data residency and RPO < 15 minutes. Automated infrastructure provisioning and configuration using Terraform and CloudFormation across dev/stage/prod environments, enabling consistent, auditable deployments and reducing manual errors by 60%. Collaborated with platform and product teams to containerize legacy services using Docker and Kubernetes, improving deployment consistency and reducing environment-related incidents by 70%.

Architected and deployed performance-optimized, high-availability infrastructure on AWS using EC2, VPC, S3, RDS, and Lambda, supporting hundreds of enterprise users with sub-second query response times. Designed and implemented load balancing architecture using HAProxy, Keepalived, and AWS Application Load Balancer with health checks, connection draining, and auto-scaling to handle traffic spikes and ensure 99.95% availability. Developed full-stack features for SolarWinds SEM, including backend APIs (Node.js, Python), frontend components (React, TypeScript), and real-time event processing pipelines using WebSockets and Kafka. Optimized database query performance and indexing strategies for Oracle and PostgreSQL backends, reducing report generation time by 50% and supporting 3x growth in event ingestion volume. Led frontend performance enhancements including code splitting, lazy loading, and caching strategies that improved page load times by 40%. Collaborated with UX designers and product managers to modernize the user interface, implement accessibility standards, and deliver intuitive workflows for security operations teams.

Developed and maintained full-stack features for a civil engineering web platform using React.js and Express.js, implementing application optimizations and frontend enhancements that improved performance by 30%. Collaborated with UX designers to modernize the user interface, implement accessibility standards, and deliver intuitive workflows for engineering teams. Strengthened expertise in full-stack development, RESTful API design, and cross-functional teamwork while supporting platform growth for hundreds of active users.
