M.R.H. Consultants Inc. designs, builds, and hardens enterprise systems — from AWS cloud architecture and Government of Canada security compliance to full-stack software. Thirty years of hands-on delivery, from one senior engineer who does the work.
Most consultants specialize in one layer. Three decades of hands-on work across infrastructure, security, and application development means the architecture and the implementation come from the same person.
AWS Landing Zone Accelerator, multi-account governance, and hybrid integration across AWS, Azure, and GCP — including Terraform-built zero-trust network gateways — with CloudFormation and CI/CD baked in.
Government of Canada CCCS guardrails, Authority to Operate (ATO), automated security response, and cross-domain solutions bridging multiple security-classification networks.
Java, Spring & Spring Boot, and Hibernate on the back end; Angular, React, and modern JavaScript on the front — a hands-on full-stack developer building, upgrading, and performance-tuning high-availability n-tier applications for government and enterprise.
Retrieval-Augmented Generation on Amazon Bedrock with Anthropic Claude — governed document pipelines, least-privilege security, and full audit traceability for public-sector data.
Large-scale migrations into Microsoft Dataverse, PowerShell and Azure Functions pipelines, Python/boto3 operational tooling built with dry-run safety and checkpointed recovery, and containerized Google Cloud Run jobs that back up SaaS platforms and keep Microsoft 365 and Google Workspace in sync.
Solana-based decentralized-storage node fleets with full deployment automation, plus on-chain token, staking, and governance programs in Rust/Anchor.
Three decades architecting and delivering secure, high-availability systems for government, public-sector, and enterprise clients across Canada, the U.S., and internationally — the kind where downtime, a security gap, or a botched migration is not an option.

Alongside client work, M.R.H. Consultants Inc. builds and operates its own software — privacy-first tools engineered to the same standard as the systems I deliver for government.
A growing family of privacy-first desktop tools that gather the decades of email, photos, documents, messages and contacts scattered across your exports, backups and old drives into one organized, local archive. It never logs into your accounts — nothing is ever uploaded.

BookingWarden watches every calendar feed and alerts by email and SMS when a booking has not reached a sibling platform, when two reservations overlap, or when a platform stops importing altogether.

I architect the solution and I write the code — from infrastructure-as-code and network security design through to full-stack application development and performance tuning.
That combination is rare. It means one person who understands how the cloud, the security posture, and the application actually fit together — so the design is realistic, the build is clean, and nothing gets lost in translation between architecture and implementation.
And when a project is bigger than one person, I scale up without handing you off — drawing on a trusted network of independent senior consultants I've collaborated with for years. You get a team's depth and capacity when you need it, with me still accountable for the work.
Where I work: I'm based in Manotick, just outside Ottawa, and work on-site with clients across the National Capital Region — Ottawa and Gatineau — and remotely for clients anywhere in Canada, the United States, and internationally. Before settling in Ottawa I lived and worked on-site abroad — with the New Zealand Police in Wellington, and with CSX Transportation and Communications Data Group in the U.S. — so cross-border engagements are familiar ground.
Three decades in, I still do this because I like the hard problems: modernizing legacy systems, securing sensitive government data, and building software that people can trust for the long haul.
Whether it's a cloud migration, a security and compliance push, a system that needs modernizing, or custom software from the ground up — I'd be glad to hear about it.
