Are fragile deployment pipelines, runaway cloud bills, or scaling bottlenecks slowing down your engineering team? When releases feel risky and infrastructure friction hinders growth, you need systems engineered for speed, security, and cost efficiency. I am a Senior DevOps Engineer with over 5 years of experience architecting high-availability cloud infrastructure, modernizing CI/CD pipelines, and driving down operational overhead. Whether you need to scale production Kubernetes clusters, migrate away from costly SaaS tools, or implement zero-downtime release strategies, I build resilient systems that scale. What I Bring to Your Infrastructure ☸️ Kubernetes & GitOps Orchestration Multi-Cloud K8s Management: Proven experience managing production environments across AWS (EKS) and Azure (AKS), handling everything from declarative operator installation to major cluster version upgrades (e.g., upgrading live clusters smoothly from v1.21 to v1.30).

Stateful Workloads: Operational administration of Kafka, Flink, RabbitMQ, and Redis on Kubernetes using custom operators and Vertical Pod Autoscalers (VPA). 🚀 Infrastructure as Code & Pipeline Automation Modular Terraform Architecture: Refactoring legacy state files into reusable, DRY Terraform modules with strict environment isolation and automated PR/MR plan guardrails. Centralized CI/CD Modernization: Designing scalable GitLab CI/CD frameworks using custom Factory Design Patterns, as well as optimizing Jenkins on Kubernetes (JCasC) to reduce Docker build sizes by up to 50% and drastically decrease build times. 💰 FinOps & Operational Cost Reduction Cloud Cost Optimization: Reduced Azure infrastructure costs by 30% using rightsizing, reserved instances, dynamic autoscaling, and serverless monitoring. SaaS Replacement: Specialized in replacing expensive third-party SaaS solutions with self-hosted, production-grade open-source stacks (Prometheus, Grafana, ELK, Loki, Harbor) without compromising performance. 🤖 AI Integration & Advanced Tooling AI Agent Delivery Workflows: Hands-on experience developing AI agent workflows, designing custom skills, and building production pipelines for AI workloads. Zero-Downtime Data Migrations: Executed seamless, zero-downtime data migrations for PostgreSQL, Redis, and multi-cloud databases. Key Work Experience Highlights Foothill Technology Solutions (Restaurant365): Architected multi-cloud Kubernetes infrastructure via GitOps (ArgoCD), built custom GitLab CI/CD Factory Component frameworks, and designed AI agent skill workflows. Homyt: Replaced Azure DevOps with Jenkins on Kubernetes, cut Azure spending by 30%, and implemented External Secrets, Harbor proxy-caching, and automated cluster security scanning. Quizplus: Refactored legacy infrastructure into modular Terraform, built enterprise AWS SES marketing campaign pipelines with reputation metric monitoring, and managed zero-downtime K8s upgrades. What Clients Usually Need Help With Stabilizing & Accelerating CI/CD: Modernizing fragile pipelines using GitLab CI/CD, Jenkins, and ArgoCD. Kubernetes Security & Reliability: Hardening clusters with RBAC, runtime protection, secret operators, and Istio/Cilium service meshes. Cloud Cost Optimization: Identifying resource waste, rightsizing infrastructure, and moving away from expensive SaaS lock-in. Infrastructure Automation: Building clean, maintainable Terraform modules for AWS and Azure setups. Complete Observability: Setting up dynamic alerting and monitoring with Prometheus, Grafana, OpenTelemetry, and ELK. Tech Stack Cloud Providers: AWS, Azure Containerization & Orchestration: Kubernetes, Docker, Helm, ArgoCD, FluxCD, Istio, Cilium, Kyverno Infrastructure as Code: Terraform, Ansible CI/CD & Automation: GitLab CI/CD, Jenkins (JCasC), Argo Rollouts, Git, Python, Bash, Java Observability & Logging: Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana), OpenSearch, OpenTelemetry, Loki, Tempo, AWS CloudWatch Data & Messaging: Kafka, Flink, RabbitMQ, Redis, PostgreSQL, AWS SES Certified Expertise ✅ 5x Certified Kubernetes Specialist: CKA, CKS, CKAD, KCNA, KCSA ✅ 2x AWS Certified: AWS Solutions Architect Associate (SAA), AWS SysOps Administrator ✅ Linux Foundation Certified: Linux Foundation Certified System Administrator (LFCS) ✅ Multi-Domain Certified: Terraform, CGOA, PCA, CAPA, ICA, OTCA, CCA, CBA, KCA If your infrastructure needs structure, your pipelines need speed, or your cloud budget is growing out of control, click the "Send Message" button below to share a brief overview of your current bottleneck.

I build mobile apps that scale cleanly and ship fast — using AI tooling to accelerate delivery without skipping the architecture work that keeps a codebase maintainable. 🔹 What I bring: ▸ 8+ years building production Flutter apps with Clean Architecture, SOLID principles, and testable, scalable codebases. ▸ Experience leading frontend technical direction on complex apps — architecture decisions, code review standards, and mentoring. ▸ Full-stack capability: I can own the mobile app and the backend it talks to (Firebase, Node.js, GCP), so you're not coordinating between multiple contractors. 🔹 AI-Augmented Development ▸ I use AI coding tools (Claude Code, Copilot, Cursor) to speed up boilerplate, prototyping, and test generation — but architecture decisions, code review, and final quality checks are always mine. ▸ This means faster delivery without the usual trade-off: you get senior-level oversight on every line, not just AI output rubber-stamped. ▸ Ideal if you need an MVP fast but don't want to inherit unmaintainable code six months later. 🔹 Frontend ▸ Flutter & Dart, native Android (Java/Kotlin) ▸ State management: Bloc/Cubit, Provider, Riverpod ▸ Offline-first apps: Hive, Drift, Firebase local storage ▸ REST & GraphQL integration, WebSockets, third-party SDKs ▸ CI/CD to App Store & Play Store via Codemagic ▸ In-app purchases, push notifications, deep links, social login, maps/places, camera/QR, Bluetooth, chat, biometrics 🔹 Backend ▸ Firebase: Auth, Firestore, Realtime DB, Hosting, Push ▸ GCP: Cloud Storage, Cloud Functions, Cloud Run, Cloud Scheduler ▸ Node.js/TypeScript: Express, node-cron, Jest ▸ MongoDB/Mongoose, PostgreSQL/Prisma ▸ Auth & security: JWT, OAuth2, RBAC, Firebase Security Rules ▸ Payments (Stripe, PayPal), Docker, Sentry, Kafka, webhooks 🔹 Engineering Practices ▸ Clean Architecture & MVVM depending on project size/timeline ▸ Test-driven development, CI/CD pipelines ▸ Agile workflows: sprint planning, code review, Git-based collaboration If you want code that's still easy to work with a year from now — not just code that works today — let's talk.
