AWS Cloud Infrastructure
Extensive experience operating mid-sized AWS accounts with 50+ EC2 instances across production, staging and testing environments, including isolated VPCs and single-tenant setups. Proficiency with EC2, RDS, S3, CloudFront, Route53, CloudWatch, Lambda, ALB, WAF, Network Firewall, ACM, KMS, and AWS Backup.
Infrastructure as Code & Automation
Management of the majority of infrastructure as Terraform code with split independently managed root configurations. Server configuration handled with Chef and Ansible, minimizing manual production changes. Automated deployments via GitHub and AWS CodeBuild, including optimized build pipelines and Lambda deployments through Serverless CLI/Framework.
Security & IAM
Application of AWS security best practices including least-privilege IAM roles, network isolation, tightly scoped Security Groups, WAF, MFA-protected AWS access keys and SSH, PKI, private DNS, and experience supporting SOC2 infrastructure controls through recurring compliance checks.
Containers & Orchestration
Hands-on experience with Docker, Compose, Swarm, Kubernetes, and Helm. Built a customer-specific Kubernetes deployment covering 15 services and a Helm chart for repeatable installation.
CI/CD Pipelines
Setup and management of CI/CD workflows using AWS CodeBuild, SSM, GitHub, Git CLI, GitHub Flow, and Capistrano to enable code-driven, repeatable and reviewable production changes.
Observability & Incident Management
Centralized logging with Vector forwarding to BetterStack, Slack alerting from BetterStack and CloudWatch using customized message templates. Diagnosis of production incidents, implementation of remediation, documenting postmortems with causes, impact and follow-up actions.
Networking
Knowledge of VPCs, routing, iptables, VPN, VyOS/Vyatta, PKI, tcpdump, Wireshark, LVS/Keepalived, pfSense, and MikroTik.
Data & Storage
Experience with MySQL, Elasticsearch, KurrentDB, Redis, Btrfs. Earlier experience with PostgreSQL, MongoDB, MSSQL, Ceph, HDFS, LVM, mdadm, and ZFS.
Scripting
Scripting capabilities using Bash, Python, and Perl to automate operational tasks and infrastructure management.
Disaster Recovery & Reliability
Design and maintenance of disaster-recovery capability with defined RTO/RPO, comprehensive backups using custom mechanisms plus AWS Backup, and an annual full recovery exercise validating the recovered stack end-to-end. Reliability work includes load-balanced/failover three-node service setups and planned database upgrades to minimize downtime.
Agentic Engineering
Use of Codex and Cursor with structured safety workflow documents for LLM agents, improving speed, thoroughness, security, traceability and documentation quality while retaining human review and operational control.

Projekthistorie
Own and evolve production infrastructure with a high degree of autonomy, from assessing existing systems and risks through implementation, monitoring, security and operational support. Manage AWS networking, compute, databases, storage, DNS/CDN, IAM/security controls, backup/DR, logging, alerting and CI/CD across production and non-production environments. Maintain the majority of infrastructure as Terraform code and server configuration with Chef. Diagnose production incidents, implement remediation and produce postmortems. Built a customer-specific Kubernetes deployment covering approximately 15 services and a Helm chart for repeatable installation. Independently owned the infrastructure Kanban backlog and task lifecycle. Working fully remote since 2018. Environment: AWS, Linux/Ubuntu, Terraform, Chef, Docker, Compose, Kubernetes, Helm, GitHub, Serverless, BetterStack, MySQL, Elasticsearch, KurrentDB, Redis.
Worked across multiple software projects on cloud/Linux infrastructure, provisioning, deployment, monitoring, networking and production operations. Supported development teams and independently troubleshot infrastructure and application-layer issues across different project architectures.
Linux, virtualization, networking, DNS, monitoring, distributed storage, provisioning, load balancing/failover and web infrastructure across multiple projects.
