I build and run the infrastructure other people's work depends on — multi-cloud platforms, container orchestration and CI/CD pipelines, with reliability treated as a foundation rather than a feature.

What I take off your plate

You run the business. I keep it running.

Uptime, backups, security, deployments and monitoring — handled end to end, so you never have to think about servers again. You get one engineer who owns the lot, not a ticket queue.

  • 24/7 uptime & monitoring

    Alerts reach me before your customers notice. I have held 99.99% uptime on a national platform at 500,000+ users an hour.

  • Backups & disaster recovery

    Automated, off-site backups and a recovery plan that has actually been rehearsed — not just assumed to work.

  • Fast, safe deployments

    Automated CI/CD: changes reach production in minutes, and a bad release rolls back in one step.

  • Security & compliance

    Patching, access control, SSL and HIPAA-grade infrastructure for regulated data — kept current, not set once.

  • Cloud setup & cost control

    AWS, Azure, GCP or DigitalOcean — sized to what you actually use, containerised, and documented.

  • On-call when it matters

    A named engineer who answers and fixes — so you can switch off in the evening and at the weekend.

Industries

Where my infrastructure runs

Regulated healthcare in the US, national government services in Bangladesh, and enterprise and marketing platforms for global brands — each with its own rules about uptime, data and change.

The work itself

Systems I keep running

Four platforms where the infrastructure was the product working or the product failing — a national government service, regulated healthcare, global brand campaigns and enterprise operations.
