Portfolio

Representative delivery scenarios for modern B2B environments.

These examples reflect the type of infrastructure work DevHubOps undertakes and the operational outcomes organizations can expect from an engagement.

SaaS Infrastructure

Multi-Environment Deployment Foundation

Provisioned staging and production stacks with automated deployments, health monitoring, access policies, and rollback coverage for a growing B2B SaaS product.

KubernetesGitHub ActionsTerraformPrometheusGrafana

Challenge

A SaaS team was deploying manually, had no environment parity, no rollback capability, and no monitoring. Production incidents were slow to detect and impossible to roll back safely.

Delivery

We designed a structured staging-to-production pipeline using GitHub Actions with approval gates, introduced environment-specific configuration management, connected Prometheus alerting, and built rollback documentation for on-call engineers.

Legacy VPS Consolidation & Hardening

Migrated fragmented workloads from five unmanaged VPS instances into documented, secure, centrally managed Linux environments with validated backup coverage.

Ubuntu ServerAnsibleNginxFail2banRsync backups

Challenge

A professional services firm had accumulated five separate VPS instances with undocumented configurations, no patch management, mixed access credentials, and no backup verification. A security audit triggered the consolidation initiative.

Delivery

We audited all existing systems, produced a migration plan, consolidated workloads onto hardened Ubuntu servers managed via Ansible playbooks, replaced ad-hoc firewall rules with documented policy, and validated backup restoration procedures.

Email Compliance

Outbound Domain Reputation Readiness

Configured compliant mail authentication, subscription controls, and sender governance to support a company's Amazon SES production access review.

Amazon SESSPF / DKIMDMARCList hygieneDouble opt-in

Challenge

An e-commerce business was rejected for Amazon SES production access due to missing authentication records, no unsubscribe mechanism, and no visible privacy or anti-spam policy. Their transactional email was also unreliable due to misconfigured SPF.

Delivery

We corrected SPF, DKIM, and DMARC records, implemented DMARC reporting, designed a double opt-in onboarding flow, built a functional unsubscribe handler, established suppression list management, and updated their privacy and terms pages to include explicit anti-spam language.
