Software Architecture Consulting and Code Audits

An audit is only worth as much as it is credible. As a member of the Ordre des ingénieurs du Québec (OIQ), Mathieu Boisvert is bound by a code of ethics that demands independence, rigor and honesty in every assessment. You get an impartial technical opinion, with no incentive to sell an unnecessary rebuild or to dramatize a healthy situation.

In practice, this means a report you can confidently present to your leadership, your board or an investor. The dual background in graphic design and software engineering adds a rare perspective: architecture is judged as much on technical soundness as on the real experience of its users.

A software code audit is the starting point for most engagements. IDNUAGE reviews your codebase, its architecture, security, technical debt and maintainability, then delivers a clear audit report: prioritized findings, risks, and recommendations ranked by impact and effort.

The deliverable is not a black box. You walk away with an actionable document, readable by both your developers and your decision-makers, that separates what must be fixed now from what can wait. Whether you are taking over a legacy project, preparing due diligence or questioning a vendor, the audit puts the facts on the table.

The right technology stack saves years of friction. IDNUAGE helps you weigh the options — Next.js, React, Node.js, PostgreSQL, Supabase, WordPress, Vercel services, AWS or Azure — against your real constraints: budget, team, deadlines, compliance and the ability to maintain the solution over time.

On the solution architecture side, the experience spans demanding systems: at La Caisse (CDPQ), the full redesign of the “Bureau numérique” involved React widgets on the Akumina CMS, integration with SharePoint, Microsoft Graph and O365, per-office content security and a CI/CD pipeline. That project won the Nielsen Norman Group's Intranet Design Annual 2023. The same rigor serves your project, at your scale.

Modernizing a legacy application in Quebec is often seen as a leap into the unknown. It shouldn't be. For Groupe Alphard, an engineering consulting firm, IDNUAGE built a custom management intranet replacing a legacy solution, with full data migration and accounting integrations — a switchover completed with no service interruption.

The method: map the existing system, isolate the risks, plan a gradual transition rather than a brutal rewrite, and migrate data with a safety net at every step. The goal is to reduce technical debt without paralyzing your operations.

Good architecture only holds if the team can carry it. Technical mentoring passes on durable practices: code review, conventions, testing, security and documented architecture decisions. As a former lead software designer at La Caisse (CDPQ), Mathieu Boisvert has guided teams on institutional-scale projects.

Whether you need a software engineering consultant in Montreal to support your developers on an ad hoc basis, validate structural decisions or raise your team's overall level, the support adapts to your context and stays remote anywhere in Quebec.
