Personal statement
Award-winning hackathon participant specializing in AI agent deployment and orchestration within Kubernetes clusters,
and active open-source community contributor. Results-driven DevOps Engineer with 5+ years of experience in
designing, deploying, and maintaining cloud & blockchain infrastructure for crypto startups - from MVP to mainnet launch
and exchange listing. Proven expertise in validator node deployment, high availability architecture, and automated
failover strategies for crypto networks. Hands-on experience with building secure and scalable environments for staking,
RPC endpoints, and multi-node setups across cloud and bare-metal. Skilled in infrastructure automation (IaC),
observability, and CI/CD tailored to fast-paced blockchain development. Deep understanding of the unique demands of Web3
platforms, with a focus on resilience, security, and operational maturity from day one.

Professional Experience
DevOps / Infrastructure Engineer
TF (NDA)
2025 (November) - Present | Full-time Remote
● Designed and shipped an internal self-service deployment platform (Coolify-based PaaS) enabling non-DevOps
developers to auto-deploy applications, removing engineering bottlenecks and accelerating delivery
● Deployed a self-hosted LLM to offload workloads from external ChatGPT/OpenAI APIs, significantly cutting
inference costs while keeping data in-house
● Own the full lifecycle of multiple production Kubernetes clusters (k3s and managed DOKS) across several
business units, from architecture and capacity planning to day-2 operations
● Drive infrastructure architecture decisions - cluster topology, node pool design, workload isolation
(taints/tolerations), and cross-provider migrations of live production workloads with zero-downtime cutovers
● Architected a hybrid GitOps delivery model on Flux CD + ArgoCD, including sync-wave/hook ordering to
guarantee safe database migrations and reliable multi-environment promotion
● Built centralized secrets management with Vault + External Secrets Operator, plus SOPS+age and
SealedSecrets for fully GitOps-native encrypted secrets
● Designed production cluster networking end-to-end: Cilium CNI, Traefik/HAProxy ingress, and dedicated egress
gateways for deterministic outbound IPs
● Deployed and operate Strimzi-managed Kafka / Redpanda event streaming with automated backup and
retention strategies for ClickHouse and PostgreSQL
● Delivered a complete observability platform - Prometheus, VictoriaM, Grafana, Loki, Alloy - standardizing a
Kubernetes labeling convention that unified dashboards, alerting, and log/metric correlation across all services
● Manage Cloudflare edge - DNS, WAF, CDN, and origin protection - as the front door for production services
 ● Standardized CI/CD on GitLab CI with self-hosted runners, and provision bare-metal/hypervisor infrastructure on
Proxmox (VMs/LXCs) with automated backup pipelines
