Hire the Best OpenStack Developers

I design fit-for-purpose infrastructure that holds up under pressure without torching the budget. I build and run multivendor production environments where systems must behave predictably through load, change, and failure. I own systems end-to-end: architecture, deployment, operations, and incident response. I kill manual toil with IaC and repeatable workflows, eradicate configuration drift, convert tribal knowledge into clean diagrams, runbooks, and a single source of truth. Security is built into the design through segmentation, least-privilege access, and automated controls, with systems documented and monitored to support audits, security incidents, and ongoing operations. I’ve seen the carnage of failed changes, vague handovers, audit nightmares, and undocumented systems that bleed operational risk daily. That’s why I build lean, observable, boringly stable platforms that scale without drama and cost less to run long-term. Experienced across enterprise, data center, and cloud environments, with industry exposure spanning telecoms, vendor support, MSP operations, financial services, low-latency trading, and large-scale service providers. 💻TECH SKILLS🥷 🌐Networking: WAN, LAN, WLAN(Meraki, UniFi), VLANs, VXLANs, IPv6, NAT, RIP, OSPF, BGP, VRF, ACLs, QoS, VPNs, DHCP, DNS, NFV 📦Virtualization: VMware, OpenStack, Hyper-V, KVM, Proxmox, Docker, SR-IOV, SAN ☁️Cloud: AWS(EC2, VPC, Flow Logs, S3, IAM, CloudWatch, WorkSpaces, WAFR), Azure(VMs, AD, Networking), Google Workspace, Office 365 ⚙️OS: Cisco IOS, Cisco NX-OS, Dell OS10, Arista EOS, Windows Server(PowerShell, AD, Group Policy, Exchange), Linux(Bash, IPtables, Permissions, Nginx), macOS 🔐Security: Firewalls(Palo Alto, FortiGate, SonicWall), CASB(Netskope), SIEM(Rapid7), MDM(MaaS360), IAM(Okta, Centrify, CyberArk), Email(Mimecast) 🤖Automation: Python(Jinja2), APIs(RESTful, NETCONF, RESTCONF), XML, JSON, YAML, YANG, Terraform, Ansible, GitHub 🛠️Tools: Wireshark, Nmap, iPerf, Cisco CIMC, Dell iDRAC, Dell OpenManage, Veeam, OpenVAS, GitHub, Postman, ManageEngine, PRTG, Zabbix, Observium, Graylog, Passbolt, NetBox, Visio, Itemit

I bring 10 years of experience in cloud infrastructure and backend development, primarily using AWS and OpenStack. I'm highly proficient in DevOps technologies such as Docker, MAAS, JUJU, Kubernetes, Jenkins, GitLab, and more. In the past 4 years, I’ve worked extensively in the blockchain industry, including 3 years managing validator nodes across multiple networks—focusing on performance, uptime, and security. I also have solid experience building blockchain applications with Rust, particularly in ecosystems like Substrate and Solana, giving me a deep understanding of low-level blockchain development.

I'm a DevOps Engineer, full-stack developer, and cybersecurity analyst with over 6 years of hands-on experience building, securing, and operating production systems end-to-end. I work across the full lifecycle , from infrastructure provisioning and CI/CD pipelines to backend services, frontend interfaces, and security audits so a single engagement can cover what would otherwise need three specialists. My core stack spans three domains: DevOps & Cloud Infrastructure - Infrastructure as Code with Terraform and Ansible; CI/CD pipeline engineering on GitLab CI (also Azure DevOps); secrets management and PKI with HashiCorp Vault; full LGTM observability stack (Grafana, Loki, Tempo, Mimir, Prometheus) with OpenTelemetry instrumentation; container deployment with Docker and Podman; hybrid cloud + on-prem operations across Proxmox and Azure; zone-segmented networking with deny-by-default firewall, WireGuard, Tailscale, and Cloudflare edge. Full-Stack Development - React, Next.js, TypeScript, Node.js, Python, and C++; modern UI work with Tailwind, GSAP, and Radix/shadcn; REST and GraphQL APIs; databases including PostgreSQL, SQL Server, MongoDB, MySQL, and Redis. Cybersecurity - penetration testing, vulnerability assessment, and security audits using Kali Linux, Metasploit, and Burp Suite. Security-first mindset applied across every layer of the work — from VLAN design to application code. What sets me apart is the range: I can take an idea from architecture and Terraform modules through to a hardened, monitored, deployable production system — without handing off to a different specialist at each layer. Available for: - DevOps & SRE engagements - Infrastructure as Code, CI/CD pipeline design, observability rollouts, secrets/PKI implementation - Cloud migration and hybrid cloud architecture (Azure + on-prem, container platforms) - Full-stack web application development (React / Next.js + Node.js / TypeScript) - Cybersecurity assessments and penetration testing - Database design, optimization, and management - System administration and IT support - Mobile application development - AI/ML integration projects

5+ years administering Linux servers, Kubernetes clusters, and network security in a government cybersecurity environment — where downtime and vulnerabilities aren't an option. I recover broken production systems fast and build hardened infrastructure that stays up. What I do: - Production incident response and recovery — diagnosing failures under pressure and getting systems back online (server recovery, database issues, crashed containers, storage problems) - Linux server administration and hardening — SSH hardening, firewall configuration, CVE remediation, security incident response - Container orchestration — Kubernetes (RKE2), Docker, Docker Compose across dev and production clusters - Infrastructure & monitoring — Proxmox VE, Grafana, Prometheus, DNS management - Databases & services — PostgreSQL, MongoDB, Redis, Kafka, ClickHouse Recent work I'm proud of: - Recovered a full production stack after a server restart caused disk devices to swap — traced the root cause through cascading database and container failures to the storage layer, and restored everything with zero data loss - Investigated and remediated a compromised production website — confirmed active CVE exploitation through log analysis, closed the entry point and secondary vulnerabilities, deployed a WAF - Built and deployed a full-stack internal web application (Next.js, PostgreSQL, Docker) serving 200+ users I communicate clearly and consistently — you'll always know the status of your systems. Whether you need an urgent recovery, a hardened server built from scratch, or ongoing infrastructure support, I bring the depth to solve problems properly, not just patch symptoms. Let's talk about what you need.

Self-driven DevOps engineer who builds and runs infrastructure that works when it matters. I've spent years working with Kubernetes, OpenShift, and Linux systems in production environments where downtime isn't an option (Banking Sector). I handle the full stack: cluster setup and operations Day0-2, infrastructure automation with Terraform and Ansible, CI/CD pipelines, and production troubleshooting when things break. I work across AWS, Azure, and on-prem environments, and I'm comfortable with both greenfield builds and fixing what's already there. My background includes networking, security hardening, and Linux administration. I've architected and deployed Red Hat platforms like Ansible Automation Platform and Red Hat Satellite. I manage SSL/TLS certificates, configure load balancing, and handle DNS. I've also deployed self-hosted AI infrastructure including vector databases and RAG pipelines on Kubernetes. I write tools in Golang when the situation calls for it. I use monitoring and observability tools like Prometheus, Grafana, and Loki to catch issues before they become incidents. I've built multi-tenant Kubernetes architectures with proper isolation, configured zero-trust networking with Wireguard, and integrated security scanning into CI/CD pipelines. I hold certifications from Red Hat, AWS, and the Linux Foundation, but what matters more is that I can diagnose problems quickly, communicate clearly, and stay engaged through tough situations. If you are looking for someone who can own infrastructure end-to-end and keep systems stable, let's talk.
