12+Years Experience
3Cloud Platforms
70%Cost Reduction
20+Certifications

As a Senior Cloud Platform Engineer and Full-Stack Engineer with 12 years of experience, I design and deliver enterprise-grade, compliant, highly available cloud architectures. I have helped teams reach 99.999% uptime, reduce infrastructure costs by up to 30%, and accelerate time-to-market by 40%.

I specialise in multi-cloud and hybrid environments (GCP, AWS, Azure), with Infrastructure as Code, zero-trust, and automated compliance. I ensure scalability, regulatory alignment (e.g. GDPR, ISO 27001) and resilience across distributed systems.

I implement Security as Code, advanced vulnerability scanning, threat modelling and CI/CD hardening, aligned with NIST, CIS Benchmarks, OWASP and other standards.

Selected Enterprise Delivery Highlights

Selected delivery outcomes from large-scale Deutsche Telekom platform work across multi-region GKE, cloud security, GitOps automation, and production reliability.

  • Built and modernized multi-region GKE platforms (DEV/PROD/SANDBOX), including Argo CD management clusters, workload clusters, and cross-region rollout patterns
  • Implemented enterprise GitOps at scale: Argo CD, Config Sync, dedicated infra repositories, reusable CI templates, and environment-driven tfvars workflows
  • Designed and migrated internal/external HTTPS load balancing with Cloud Armor in multi-cluster topologies, including policy hardening, Adaptive Protection, and incident tuning
  • Delivered secure access architecture for developers: OIDC/WIF, IAP jump-host patterns, least-privilege IAM, group-based access, and audited access flows
  • Led platform data-layer engineering with Cloud Spanner (PostgreSQL/Cassandra adapter), Memorystore Redis Cluster, Astra DB over PSC, CMEK and backup strategy
  • Implemented certificate lifecycle improvements: Google-managed certs, TeleSec ACME automation, cert-manager flows, DNS validation, and TLS policy hardening (HSTS, cipher controls)
  • Migrated critical network and security controls from manual ops to Terraform + CI/CD (Cloud Armor, firewall baselines, address groups, external LB modules) for DEV and PROD parity
  • Improved operational excellence through runbooks and deep-dive guides (Cloud Armor, Multi-Cluster, VPC Firewall, incident response), plus on-call readiness and RCA support

Security & Compliance Outcomes

  • PSA and policy control alignment across cloud services, with implementation patterns mapped into platform delivery
  • IAM hardening with least-privilege roles, Workload Identity/WIF, group-based access, and reduced long-lived credential exposure
  • TLS policy hardening on load balancers: deprecated protocol removal, stronger cipher posture, and HSTS enablement
  • Cloud Armor and WAF tuning with targeted exclusions and policy refinement to reduce false positives while preserving protection
  • Security-as-Code rollout via Terraform/OpenTofu and CI/CD for repeatable controls in DEV and PROD
  • Operational security maturity through incident runbooks, troubleshooting guides, RCA support, and on-call readiness improvements
