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. Rate progressed $40/hr → $52/hr based on results. ▪️ GetChecked (Blockchain / Multi-cloud) → Challenge: Multi-cloud infrastructure (AWS + DigitalOcean + bare-metal) with Hyperledger Fabric in a regulated environment. → Solution: Upgraded Hyperledger Fabric, implemented monitoring, backup, DR/BCP, optimized CI/CD pipelines. → Business Impact: Increased system reliability and security in a strict regulatory context. Core SRE Capabilities → DORA metrics: Deployment Frequency, Lead Time, MTTR, Change Failure Rate - measured and improved → Incident Management & On-Call: Runbooks, escalation paths, post-mortems → Disaster Recovery & Business Continuity planning and testing → Zero Trust Security: IAM, RBAC, SELinux, network hardening → High Availability: Multi-AZ, failover, load balancing, autoscaling → AI workload reliability: observability for ML pipelines and LLM infrastructure Stack: AWS · GCP · Kubernetes · Terraform · Ansible · Prometheus · Grafana · ELK Stack · Datadog · Zabbix · Docker · Linux · GitHub Actions · GitLab CI · Incident Response Plan · Disaster Recovery Available during US business hours (EST/PST overlap). Downtime is a solved problem - if you have the right observability. Send an invite and let's audit your reliability posture.

I work with engineering leaders and CTOs who are scaling fast but fighting the same battles: deployments that take hours, environments that drift, DevOps bottlenecks that block every release, and infrastructure that isn't ready for AI workloads. I eliminate those bottlenecks - permanently. With 90+ completed projects, $900K+ earned on Upwork, and a 100% Job Success Score, I've led infrastructure transformations across Fintech, Healthcare, E-commerce, and SaaS - delivering measurable outcomes that show up on the P&L, not just in a CI/CD dashboard. Typical Problems I Solve → Deployments take hours instead of minutes → Infrastructure costs keep growing without visibility → DevOps bottlenecks block engineering teams → Kubernetes environments become difficult to maintain → AI initiatives are delayed because infrastructure isn't ready → Need a DevOps engineer for cloud migration or infrastructure audit Proven Client Results ▪️ HRM Platform → Challenge: Deployments took 3 hours, causing constant developer delays and release anxiety. → Solution: Docker parity environments + fully automated CI/CD pipeline across all environments. → Business Impact: Deployment time cut from 3 hours to 2 minutes - 98% improvement in release speed. ▪️ Connectivity Platform → Challenge: Provisioning a new environment took 1.5 weeks, blocking team velocity. → Solution: Infrastructure automation with Terraform + CI/CD pipeline standardization. → Business Impact: Provisioning time cut to 1 hour. 200-300 monthly automated deployments. Team efficiency +30-35%. ▪️ Zmyle (German E-commerce, 17+ multi-tenant sites) → Challenge: Legacy infrastructure couldn't handle Christmas peak traffic across 17 sites. → Solution: Full migration to Kubernetes with CI/CD, monitoring stack (Prometheus/Grafana/ELK), and VPN. → Business Impact: Zero downtime during peak season. Scalable multi-tenant architecture now handles 10x traffic spikes. What Working With Me Looks Like → DORA metrics-driven delivery - Deployment Frequency, Lead Time, MTTR, Change Failure Rate measured and improved → Zero-Drift Infrastructure - no more 'works on my machine' incidents → FinOps awareness built into every pipeline - cost visibility is not an afterthought → AI-ready infrastructure - prepared for LLM workloads, GPU orchestration, and vector databases → Full observability stack: Prometheus, Grafana, ELK, Datadog - you see everything I lead a team of Senior DevOps Engineers and Cloud Architects. Whether you need a one-time infrastructure audit or a long-term engineering partner - I structure engagements around your business outcomes, not billable hours. Industries: Fintech · Healthcare · E-commerce · SaaS · Blockchain Stack: AWS · GCP · Azure · Kubernetes · Terraform · GitOps · ArgoCD · Prometheus · Grafana · GitHub Actions · GitLab CI · Docker · Ansible · AI workloads Available during US business hours (EST/PST overlap).
