​6+ Years Engineering High-Availability Cloud Infrastructure, Proactive Observability, and Bulletproof CI/CD Pipelines. ​In production, downtime isn’t just an inconvenience, it’s a revenue killer. As a Senior SRE and DevOps Engineer, I bridge the gap between development and operations to ensure your applications are highly scalable, resilient, and transparent. My core philosophy relies on proactive reliability: designing system observability, synthetic monitoring, and robust SLO/SLI frameworks to catch and resolve anomalies before they ever impact your end users. ​Whether you need to containerize legacy workloads, automate infrastructure from scratch via Code (IaC), or build comprehensive, multi-layered dashboards for enterprise-level visibility, I engineer stable environments that empower development teams to deploy with confidence. ​Core Areas of Expertise: ​Observability & Monitoring: Deep experience designing end-to-end telemetry across enterprise stacks. Proficient in Datadog, Dynatrace, ELK, Grafana, Prometheus, AppDynamics, Nagios, and Kibana. Specialized in alert tuning, synthetic monitoring, and SLO/SLI mapping. ​Cloud & Container Orchestration: Advanced provisioning and management across AWS and Azure. Expert-level containerization with Docker and Kubernetes (EKS/AKS cluster management, scaling, and security). ​Infrastructure as Code (IaC) & Configuration: Building modular, reusable infrastructure using Terraform, alongside automated configuration management with Ansible and Chef. ​CI/CD & Automation: Architecting reliable continuous integration and continuous deployment pipelines that accelerate release cycles while maintaining strict quality gates. ​Operations & Support: Extensive background in L3 Application Support, web development, hands-on incident response, and executing robust disaster recovery strategies. ​Why Work With Me? ​Enterprise-Ready Communication: I translate complex technical infrastructure into high-impact, accessible insights for stakeholders and business owners. ​Self-Driven Execution: Comfortable operating autonomously, managing workflows, writing rigorous technical documentation/runbooks, and collaborating across timezone-agnostic teams. ​Culture of Collaboration: I do not just fix servers; I foster a true DevOps culture of shared responsibility, automation, and continuous improvement. ​Let’s ensure your infrastructure is built to scale.

Every hour of downtime costs your enterprise an average of $540,000. That's not a DevOps metric - that's a board-level problem. I design and operate infrastructure that stays up. My specialty is the full observability and reliability stack: detecting failures before users do, recovering in minutes, not hours, and building the self-healing systems that let your engineering team sleep at night. With $400K+ earned on Upwork, 100% Job Success Score, and 10+ years in DevOps and Site Reliability Engineering, I bring the broadest monitoring stack you'll find in one engineer: Prometheus · Grafana · Datadog · ELK Stack · Zabbix · Sumo Logic - combined with deep Kubernetes and cloud expertise. Typical Problems I Solve → Production incidents are frequent, and MTTR is too high → No observability - issues discovered by users, not monitoring → Need DevOps engineer for high availability infrastructure setup → Kubernetes clusters experiencing performance or reliability issues → Disaster recovery plan missing or untested → AI workloads need reliable, observable infrastructure Proven Client Results ▪️ iLost Platform (Netherlands) → Challenge: EKS performance degrading, CI/CD unstable across Dev/Staging/Production, and OpenSearch causing timeouts. → Solution: EKS rightsizing, CI/CD pipeline optimization, IAM hardening, OpenSearch performance tuning. → Business Impact: Reduced bottlenecks, improved release predictability, and optimized infrastructure costs. ▪️ Qopla Infrastructure → Challenge: Long-term SRE engagement - ongoing reliability, monitoring, and performance needs. → Solution: Continuous SRE operations, incident management, and infrastructure optimization. → Business Impact: 657-hour engagement demonstrating sustained impact.
