• Platform & Multi-Cloud Leadership: Own cloud strategy and platform engineering across AWS, Huawei Cloud, and Hetzner for an automotive marketplace serving 1M+ users; lead the DevOps team while staying ~70% hands-on with architecture and code.
• Infrastructure as Code & GitOps: Moved infrastructure to 100% Terraform with GitOps via ArgoCD and Helm, making every deployment consistent and auditable.
• Modernization: Led the monolith-to-microservices shift for 1M+ users, authoring a multi-runtime Helm chart that standardized scaling, probes, and networking across all services.
• Custom Tooling & CI/CD: Built a Go Kubernetes operator for bespoke provisioning integrated into Helm/ArgoCD delivery; Jenkins + ArgoCD pipelines with a private OCI registry and Kong gateway improved deployment speed by 60%.
• Reliability, Cost & Security: Achieved 99.999% uptime with automated cross-region DR (Ansible, Huawei SDK) and a Prometheus/Grafana/Loki stack; cut infrastructure cost 20% while meeting PCI-DSS and SOC2 (Keycloak, WAF/VPN, KMS).
• Team Leadership: Lead the DevOps team and platform roadmap, run internal Kubernetes and Docker training for product teams, and own vendor relationships and overall cloud strategy.

• Platform Governance: Platform Owner for the bank's cloud ecosystem: 15+ AWS accounts and 20+ production microservices, focused on high availability, disaster recovery, and fintech workload optimization in a regulated environment.
• Infrastructure as Code & GitOps: Standardized deployments with Terraform and GitOps (ArgoCD via Atlantis) for consistent, repeatable releases; managed autoscaling and resource optimization for production workloads.
• Security & Compliance: Reached a 96% security posture across all accounts via IAM Identity Center, AWS Organizations, and PCI-DSS controls (CloudTrail, AWS Config, Security Hub).
• Automated CI/CD: Orchestrated end-to-end delivery pipelines with AWS CodePipeline and GitHub Actions, automating testing and security scanning from development through production.
• Release Engineering: Led weekly zero-downtime releases and hotfix strategies with rollback and go/no-go decision frameworks across dev, QA, and production.
• Production Support & Monitoring: Supported production microservices through centralized monitoring (Prometheus, Grafana, CloudWatch), incident response workflows, and long-term platform roadmap planning.

• Solution Architecture: Architected AWS hybrid and on-premises solutions for 8+ enterprise clients including fintech; designed microservices, event-driven, and serverless architectures and cut cloud costs 25% to 40% through right-sizing and reserved instances.
• IaC Foundation & Standards: Built foundational Terraform/Terragrunt patterns and multi-account AWS Organizations setups, plus reusable modules and Python/JavaScript libraries for infrastructure automation and DevOps documentation standards.
• Container Platforms: Managed containerized workloads across ECS, Fargate, and EKS spanning dev, UAT, and prod, deploying with GitOps practices and hardened container images.
• CI/CD & Compliance: Implemented secure pipelines (GitHub Actions, CodePipeline/CodeBuild) with canary deployments, automated testing, and security scanning across multi-region and on-premises environments.

• Fintech Microservices: Built secure, scalable Spring Boot microservices with PostgreSQL for financial transaction processing across the full SDLC.
• Full-Stack Development: Developed Angular front-end components and resolved production bugs and performance issues to improve system stability.
• Technical Documentation: Authored detailed technical documentation to support long-term maintainability and knowledge transfer across teams.

• Client Consultations: Ran end-to-end client consultations to align requirements and solutions, managing timelines, deliverables, and expectations through delivery.
• Backend & Fintech: Designed and built Spring Boot microservices with PostgreSQL for fintech clients, integrating databases for reliable data persistence.
• Responsive Web: Built responsive React, HTML, and CSS interfaces focused on user experience and performance.

Achievements: First place in the individual project at the annual Technology Day contest; contributed to founding and growing the Faculty of Information Technology Club.
