I’m a Senior Golang Engineer, DevOps Architect, and Fractional CTO with 15+ years of experience building scalable, secure, and high-performance systems for Fortune 100 companies and fast-growing startups. I help companies accelerate delivery, stabilize infrastructure, eliminate bottlenecks, and scale products from MVP to enterprise-grade. I specialize in designing backend systems, architecting cloud-native infrastructure, and building automation that makes engineering teams significantly faster and more productive. My background includes senior roles at Akamai, Shell, and The Home Depot, where I built Golang microservices, Kubernetes-native platforms, large-scale ingestion pipelines, multi-cloud environments, and high-availability distributed systems. I’ve also advised and supported multiple startups as a fractional CTO, helping founders design strong technical foundations, optimize cloud costs, build their first engineering processes, and launch stable production systems. What I Do Best * Golang Engineering * High-performance APIs and microservices * Enterprise-grade ETL and ingestion pipelines using Go routines * Concurrency-heavy backend systems * API integrations, data processing, automation tools, CLIs DevOps & Cloud Architecture * Kubernetes (EKS, GKE, AKS) architecture and automation * CI/CD pipelines (GitHub Actions, CircleCI, ArgoCD, Azure DevOps) * Docker, container security, infrastructure hardening * AWS, Google Cloud, and Azure environments * Kafka, RabbitMQ, Elasticsearch, Redis Fractional CTO Services * Technical roadmap & architecture design * Scaling platforms and improving reliability * Cloud cost optimization * Engineering process cleanup and team enablement * Systems modernization and infrastructure reviews Career Highlights * Architected a production-grade Kubernetes security platform at Akamai powering global workloads. * Built delivery confirmation systems at Shell that improved cash flow by over $300M. * Designed high-throughput Kafka ingestion pipelines for The Home Depot. * Built a nationwide property records ETL system processing 150M+ records. * Developed eCommerce, analytics, billing, and data platforms used across multiple industries. Why Clients Work With Me * I deliver senior-level engineering and architecture, not mid-tier guessing. * I communicate like a CTO: clear, precise, proactive. * I build solutions that scale, save money, and reduce operational pain. * I can code hands-on, lead technical strategy, or do both. * I take on both large projects and smaller focused engagements. If you need a high-caliber backend engineer, cloud architect, or fractional CTO who can deliver reliable systems and accelerate your roadmap, I’d be happy to help. Let’s build something exceptional.
