DevOps

• Developed and launched the company's first observability dashboard, providing real‑time system performance insights and data visualization on the large office TV.
• Designed, deployed, and maintained 10 PostgreSQL and MS SQL servers on Ubuntu Linux VPS, ensuring optimal server performance and reliability.
• Enhanced data security by implementing 1,000 RBAC rules for developers, application instances, PostgreSQL, MS SQL, and other Linux servers, preventing unauthorized access; documented with Ansible automation.
• Automated GIS SaaS application deployment, data processing, and reporting system using GitHub Actions CI/CD, Python, Bash, and SQL.
• Automated delivery of 20 GIS data pipelines and app data ETL processes, streamlining infrastructure automation and reporting.
• Automated 100 critical data backups using Barman, Google Cloud, Bash, and Python, ensuring data integrity across databases.
• Deployed and maintained 20 Docker containerized applications, troubleshooting with Podman and Kubernetes, and managing R‑based apps on Google Cloud and AWS.
• Managed 30 Ubuntu Linux VPS instances, implementing disaster recovery strategies and ensuring optimal network configurations.
• Mitigated operational risks by implementing a monitoring dashboard using Grafana and Prometheus, improving system reliability.
• Automated SSL/TLS certificate creation for 100 Docker applications, ensuring secure connections across Ubuntu Linux hosts.
• Streamlined CI/CD processes, saving 4,000 hours by introducing automation in software development pipelines.
• Streamlined data analysis and software development processes, saving 4,000 hours by introducing GitHub, GitLab, Bash, and Python CI/CD practices.
• Optimized budget costs 10 times with zero loss in productivity for the Saudi Arabia company by reimagining the overall infrastructure, eliminating unnecessary services, and relocating from the AWS cloud.
• Generated the API contract outward from the database — OpenAPI, a 44,076‑line typed TypeScript client, 61 mock handlers and the limits the UI enforces — with a guard at every hop that fails on drift.
• Provisioned Azure infrastructure as code with Bicep — Container Apps, PostgreSQL Flexible Server, Front Door/WAF and networking — across the development, staging and production environments.
• Built GitHub Actions CI/CD pipelines with a distroless production frontend image and multi‑environment promotion.
• Authored 578 go‑task automation targets spanning native, Docker and HTTPS dev modes, linting, testing, database and deployment.
• Owned end‑to‑end deployments of the platform to Azure, managing releases across development, staging and production environments.
• Configured database backup retention as infrastructure‑as‑code, then audited the recovery position and documented the restore procedure — naming the remaining gaps rather than leaving them to be found during an incident.
• Set a zero‑warnings quality bar across six languages — Go, TypeScript, SQL, Python, Shell and Markdown — enforced by pre‑commit hooks.
• As one of the first hires, designed and built the entire core infrastructure and supporting processes from scratch for a green‑energy SaaS startup, laying the foundation for rapid growth.
• Automated team collaboration, password management, task and time management, and built a semi‑automatic project‑showcase system, raising team productivity.
• Built a layered automated test suite — 981 Go tests, 543 frontend and browser specs, 494 SQL behavioural tests — with mutation testing, property‑based tests and an accessibility gate.
• Built the repository's guard engine — 268 registered commit checks, 277 lint rules and 15 custom ESLint rules — plus 146 tests of the guards themselves, so the build holds the standard, not review.
• Built first‑party error monitoring and OpenTelemetry tracing rather than buying them — payload sanitising, spike and regression detection, symbolication and a synthetic heartbeat — behind 11 operator views.
• Kept the schema honest across 1,022 migrations with a CI gate that builds the database both ways — a fresh install, and an install plus every migration — and fails when the two disagree.
• Established a continuous security programme — code scanning, DAST, dependency and vulnerability checks, SBOM generation, secret scanning and SHA‑pinned actions — alongside 21 written security audits.
• Built the company's own infrastructure as 19 Ansible playbooks and 34 roles across 12,065 lines of YAML, converging a live host to a declared state with every play idempotent.
• Made check mode tell the truth across the whole platform after finding six probes deciding on a value the host never gave, because Ansible's command module reports success under --check while skipping the command entirely.
• Added a preflight play that runs the same code as the converge against operator‑local secrets in about a second, after a half‑applied production run died on its ninth task with the swap settings already written to the live host.
• Deployed the company's own git forge on Soft Serve, private by default with no web panel and its SSH port bound to loopback behind a jump host, and made the landing page in front of it a build artefact of the main site rather than a hand‑kept copy.
• Deployed a container plane on Podman and Quadlet under systemd rather than Docker, because Docker publishes container ports above the host firewall's own rules — and gave deploys an unprivileged user with one fixed command instead of root.
• Built a commit gate of 22 one‑line linters plus five that earn a paragraph, with no warning tier and no inline suppressions permitted, covering HTML, CSS, JavaScript, Python, YAML, Markdown, shell, links, spelling, secrets and typography.
• Cut the site's browser‑driven quality gate from 1,636 seconds to 615 by scheduling its checks longest‑first through a worker pool bounded to four lanes, after measuring that alphabetical order cost 320 seconds against 224.
• Brought 10,242 lines of quality‑gate JavaScript under a formatter and a linter after establishing it was the largest body of code in the repository and the only one nothing read, fixing 13 findings and suppressing none.
• Held the generator to 981 test cases at a 92% branch‑coverage floor with warnings treated as failures, and asserted idempotence by running the whole build pipeline twice from an empty file and requiring the second pass to change nothing.
• Selected every rule the Python linter has as an error, working through 1,815 findings to reach zero, with each of the few exemptions carrying a written reason and two of them backed by a checker instead of a comment.
• Found the commit hooks and the quality gate running different checks while a document promised they were the same, by comparing the two lists in a test — the five that only ever ran by hand were the ones reading the CV prose.
• Rehearsed the forge‑side CI hook and found two defects unreachable by reading the file: a fallback that put an unresolvable argument on the hook's input, and git's own environment variable following the gate into the checkout and turning 19 tests red.
• Took the test suite from six tests over a sixty‑second limit to 135 passing in 8.9 seconds by profiling the main thread and removing the two calls it sat inside for 3,989 samples out of 4,017.
• Audited 644 Rust crates for licence compatibility on every build, and proved the check fires by rewriting one crate's licence and by moving the pinned core revision without regenerating.
• Held four repositories to one history standard — conventional, emoji‑free, no attribution trailers, enforced by a commit‑message hook — alongside 46 instruction documents that govern how the work is done.

This work is part of what we offer as DevOps & CI/CD Automation, Technical Leadership & Consulting, Infrastructure as Code, Security & Access Management, Cloud Infrastructure & Migration, System Administration, Site Reliability & Monitoring and Technical Documentation.
