🏆 Top Rated Freelancer | 100% Job Success Your cloud infrastructure should help you move faster, not become the reason deployments fail, security gaps grow, or your team spends hours troubleshooting production issues. With over 8 years of hands-on experience in DevOps, Cloud Engineering, and Cloud Security, I help startups, SaaS companies, and growing businesses build secure, scalable, automated, and production-ready environments across AWS, Microsoft Azure, Google Cloud Platform (GCP), and DigitalOcean. Whether you need to build cloud infrastructure, secure an existing environment, automate deployments, improve observability, or prepare your platform for production, I focus on practical solutions that improve reliability, security, and operational efficiency. I don't just deploy infrastructure. I look at how your systems are built, accessed, deployed, monitored, secured, and recovered. Here's what I bring to your project: ✔ Cloud Infrastructure & DevOps AWS · Azure · GCP · DigitalOcean · Docker · Kubernetes · Helm · Terraform · CloudFormation · Ansible · Crossplane · Load Balancers · NGINX · VPCs · VPNs · Firewalls. I build repeatable infrastructure designed for reliability, scalability, and easier operations. ✔ Cloud Security & Identity IAM · Microsoft Entra ID · RBAC · Azure Policy · Defender for Cloud · Azure Key Vault · MFA · Conditional Access · Authentication · Authorization · Encryption · Zero Trust. I help you control who can access your infrastructure, what they can access, and how that access is protected. ✔ DevSecOps & CI/CD Security GitHub · GitHub Actions · GitLab · Jenkins · Azure DevOps · CI/CD · SonarQube · OWASP ZAP · Trivy · Secret Scanning · SAST · DAST · Dependency Scanning. I integrate security checks into delivery pipelines so vulnerabilities can be identified before they reach production. ✔ Infrastructure & Network Security I review cloud exposure, firewall rules, ports, DNS, VPNs, SSL/TLS, ingress, reverse proxies, public services, and network access to reduce unnecessary exposure and strengthen your infrastructure security. ✔ Secrets, Git & Environment Security I work with repository permissions, branch protection, deployment credentials, CI/CD secrets, service accounts, environment separation, and secrets-management practices to reduce the risk of unauthorized access and credential exposure. ✔ Monitoring, Logging & Observability Prometheus · Grafana · Loki · Datadog · CloudWatch · OpenLens. I help you establish meaningful monitoring, centralized logging, alerting, and visibility so your team can detect and troubleshoot issues faster. ✔ Automation & Scripting Python · Bash · Automation · Infrastructure Provisioning · Deployment Workflows. I automate repetitive cloud and operational tasks to reduce manual work and improve consistency. ✔ DNS & Email Security DNS management · SPF · DKIM · DMARC. I configure and troubleshoot domain and email authentication records to improve security and email deliverability. ✔ Reliability, Backup & Recovery I help implement backup strategies, disaster recovery, restore testing, monitoring, and recovery processes so your critical workloads are protected when things go wrong. ✔ Security Assessment & Remediation I assess cloud exposure, IAM, secrets, databases, storage, APIs, authentication, authorization, tenant isolation, logging, CI/CD, and application security, then document findings, support remediation, and retest fixes.
