I develop the most robust error free reliable applications using MS Access and MS Excel. All databases have a strong table structure and are split form the from end user interface. All VBA code is tested and the applications are customized to your needs. Even custom ribbons are added to make your application indistinguishable from MS Access so that you never know you are using and MS product. SQL Server backed work has been done for many clients. The applications I developed are backed with security from unauthorized changes and are ensured to meet all of your business requirements. I will always go the extra distance for my clients.

Slow deployments, fragile CI/CD pipelines, or an AWS or Azure bill that climbs every month while nobody knows why? These are DevOps problems. I fix them: most recently cutting a client's infrastructure costs by 35% while taking their deployments from weekly to daily. I am a DevOps Engineer with 8+ years of experience building, automating, and securing production cloud infrastructure on AWS, Microsoft Azure, and Google Cloud. I help startups and product teams ship faster with reliable CI/CD pipelines, scalable Kubernetes clusters, and Infrastructure as Code (Terraform) that removes human error from every release. Recent results:  Multi-region Amazon EKS (Kubernetes) platform with Karpenter autoscaling and ArgoCD GitOps: infrastructure costs down 35%, deployment frequency up from weekly to daily.  Real-time data pipeline on Microsoft Azure processing 5M+ data points per day: processing lag cut from 3 hours to under 10 minutes.  Zero-downtime migration of a production monolith to containerized microservices in 6 weeks, including full CI/CD automation and safe rollback strategy.  Production AI workloads (LLM serving, vector databases, RAG pipelines) deployed with the same DevOps discipline as any other service: automated pipelines, monitoring, autoscaling. Query latency cut from 4s to under 800ms at 200k+ documents. WHAT I HELP CLIENTS WITH: ✔ CI/CD pipeline design and automation: GitHub Actions, GitLab CI/CD, Jenkins, Azure DevOps ✔ Kubernetes setup, hardening, and optimization: EKS, AKS, GKE, Helm, Istio ✔ Infrastructure as Code: Terraform, Ansible, Pulumi, CloudFormation ✔ Cloud migration to AWS and Azure with zero-downtime, low-risk cutover plans ✔ Docker containerization and microservices infrastructure ✔ Monitoring and observability: Prometheus, Grafana, Loki, Datadog, ELK Stack, CloudWatch ✔ Cloud cost optimization and FinOps reviews (typical savings 30 to 40%) ✔ DevSecOps: Vault, Snyk, OPA, secrets management, SOC 2 and ISO 27001 readiness ✔ AI and LLM infrastructure (LLMOps): taking AI features from prototype to production TOOLS AND TECHNOLOGIES: Cloud platforms: AWS (EKS, ECS, EC2, Lambda, RDS, S3, VPC, IAM), Microsoft Azure (AKS, Azure DevOps), Google Cloud (GKE) Containers and orchestration: Kubernetes, Docker, Helm, Kustomize, Istio, Karpenter Infrastructure as Code: Terraform, Ansible, Pulumi, CloudFormation CI/CD and GitOps: GitHub Actions, GitLab CI/CD, Jenkins, ArgoCD, FluxCD, blue-green and canary deployments Monitoring: Prometheus, Grafana, Loki, Thanos, OpenTelemetry, Datadog Security and compliance: Vault, Snyk, OPA, Falco, IAM least privilege, SOC 2, ISO 27001 Scripting and automation: Python, Bash, Node.js WHY TEAMS HIRE ME: I have been on-call for enough production incidents to know what actually breaks and why. You get honest assessments, not tool-selling: if a small fix solves your problem, I will tell you before proposing a rebuild. Clear communication, documented handovers, and infrastructure your own team can operate after I am gone. If your pipelines are fragile, your Kubernetes costs are climbing, or releases still need a human babysitting them, send me a message describing your current setup. I will come back with a clear assessment and concrete next steps within 24 hours.
