Available now for contract engineering, small-business automation (including Odoo), and hands-on IT consulting in Vernon & Kamloops.

Why teams call me

  • Led teams that shipped systems saving real, measured costs.
  • Comfortable owning a codebase end-to-end, or slotting into yours.

Four ways to work together

Pick the engagement that fits — a short paid audit, an ongoing contract, an automation project, or hands-on local support.

Freelance & Contract Development

Available now

Full-stack, backend, or cloud work on a contract or project basis — direct, or through Upwork, Toptal, or Contra. Quick to onboard, comfortable working async across time zones.

  • Full-stack web apps: React, Angular, Node, Python, Java
  • Cloud infrastructure: AWS, GCP, Kamatera, Docker/Kubernetes
  • Healthcare & regulated-data systems (HL7/FHIR)
  • Short sprints or long-term engagements
Discuss a contract

Code & Architecture Review

From $500 flat-rate

A fixed-price audit of your codebase or architecture — what's fragile, what's overbuilt, what will bite you at scale. Delivered as a clear, prioritized written report, no jargon.

  • Architecture & scalability review
  • Security & data-integrity pass
  • Prioritized findings with concrete next steps
  • Typical turnaround: 3–5 business days

Local IT & Software Consulting

Vernon & Kamloops

On-the-ground help for local businesses: systems that don't talk to each other, aging software that needs a plan, or a second opinion before a big purchase. In person or remote.

  • Systems assessment & vendor-neutral advice
  • Integrations between existing tools
  • Small business software builds
  • Fast local turnaround, no shipping delays

Business Automation for Small Business

Fixed-scope or monthly

Quotes re-typed into invoices. Inventory that lives in one person's spreadsheet. Three systems that don't talk to each other. I map the workflow you actually run, then automate the step that's costing you the most hours — not the whole company at once.

  • Quoting, invoicing, inventory & purchasing workflows
  • CRM, accounting and e-commerce sharing one source of truth
  • ERP implementations — including Odoo, or taking over one already in flight
  • Start with one process, measure what it saved, then the next
Automate a workflow

A note on tooling: I recommend the tool that fits your business, not the one I resell — I'm not a reseller of anything. In practice Odoo is where I go deepest, and I'm happy to pick up an Odoo implementation that's stalled, over budget, or was left half-finished by someone else.

About

An unusual path into software

I trained as a physician — a Doctorate of Medicine from the University of Calgary and a residency year in Radiation Oncology — before moving into software full-time in 1998. That background shows up in how I work: diagnose before you treat. I'd rather spend an hour understanding what's actually broken than a week guessing.

Since then I've been a developer, team lead, director and instructor across healthcare technology, logistics, and AI startups — including early contributions to HAPI FHIR, a widely-used open-source library for HL7 healthcare data exchange. I also hold a BC Teaching Certificate, which comes in handy when a code review needs to actually be understood, not just filed away.

I run Tacteon Ltd as my own consultancy, and take on select outside contract, audit, and local consulting work alongside it.
