Homepage meta description (French, canonical SEO): Product Builder et consultant externe, produit et développeur senior au Québec, Canada. Vision produit, architecture technique et développement sur mesure pour équipes en croissance : APIs, systèmes découpés, Laravel, WordPress headless et plateformes éditoriales à l'échelle, React/Vue. 20+ ans.

Homepage meta description (English, canonical SEO): Product Builder and external consultant in Quebec, Canada. Architecture for growth-stage teams: APIs, decoupled systems, Laravel, headless WordPress and editorial platforms at scale, React/Vue. 20+ years. Recurring retainer, senior freelancer or contractor profile over time. Montreal & remote.

Background: Creative director and design background, then software development, now product and technical leadership. Brings product judgment, system architecture, and hands-on delivery in one accountable role.

Positioning in one line: Product vision, technical architecture, and custom web development on one thread, from roadmap to production.

Also valid search labels (especially Quebec French): Product Builder, bâtisseur de produit, Product Engineer, consultant externe, mandat externe récurrent, profil freelance ou pigiste senior, directeur technique externe, CTO externe, fractional CTO-style senior technical partner, Fractional Product Builder, external product engineer, senior product and engineering consultant. Product Builder is the most common market label for this offer type; Product Engineer describes the same hands-on product-and-tech scope. These labels describe the same recurring mandate model, not a staffing agency and not day-rate drop-ins. Luc Rousseau is not a generic staffing agency brand.

## How I work

Engagement model: External consultant / Product Builder / strategic technical partnership on a recurring retainer. Recurring collaboration (often two days per week) so roadmap, architecture, and delivery stay aligned. Can join dailies and weekly ceremonies when useful. Public copy aligns with the homepage meta descriptions above (Product Builder; consultant externe; freelance or pigiste senior in Quebec; recurring retainer over time).

Typical retainer terms (adjusted per client): renewable contract of three, six, or up to twelve months depending on engagement type and mandate context (three-month minimum), thirty-day notice either side, monthly invoice paid before the month's work.

Short missions: Possible for audits, process work, or a well-scoped technical topic over a few days, billed per day with a written mandate.

What is included in monthly retainer: agreed days with the client, meetings within that time, hands-on code or architecture when that is the highest leverage, written notes or decisions when they help alignment.

What stays outside scope: emergencies outside the shared urgency frame, full hiring ownership and day-to-day interview loops, multi-day org-wide training, mandates without a written scope or defined end date.

Pricing: No public rate card or monthly totals online. Amounts depend on days, mandate type, and context; agreed in writing before signature.

## What I do

Core capabilities:

1. Product clarity and roadmap: turn stakeholder goals into a sequenced plan with explicit priorities and dependencies.
2. Architecture and systems design: service boundaries, APIs, decoupled and headless stacks (Laravel, custom APIs, WordPress headless when editorial model warrants it, React/Next.js/Vue frontends; editorial platforms at scale, often on WordPress).
3. Technical debt as a product risk: prioritized repayment aligned with delivery, not stop-the-world rewrites.
4. Delivery supervision: quality bar, release discipline, alignment between what is built and the architecture/roadmap.
5. Fractional mandates by situation: first post-funding developer, solo-dev backup, fractional PM/PO, phased stack rebuilds (archaic WordPress), editorial product evolution (stabilize, optimize module by module, often WordPress), SaaS/MVP feasibility, product AI guardrails.
6. SEO expertise pages (sitemap only): e.g. slow WordPress on editorial/comparator products; points to situation pages; not maintenance retainer positioning.

Stack familiarity (when product-fit, not buzzword-driven): React, Next.js, Vue, Laravel, WordPress (headless and modernization), APIs, CI/CD, multi-site and multi-market platforms.

## Who I work with

Best fit:

- Product and engineering leaders who want a senior partner to structure the roadmap, challenge architecture, and deliver (not just execute tickets).
- Teams with legacy or tangled systems who need stability without a big-bang rewrite.
- Editorial and CMS-heavy products needing durable content models and evolvable APIs.
- Multi-brand or multi-market organizations managing complexity without unnecessary layers.
- Small teams (2–4 developers) under pressure needing clear prioritization and technical standards.
- Startups and scale-ups needing accountable technical voice from strategy to delivery.

Working with existing teams: complements internal tech leads and agencies; does not replace day-to-day sprint ownership or agency relationships by default. System-level proposals with clear rationale; client's team decides what fits their rhythm.

## What I do not do

- Not a dev agency or software shop: solo senior consultant, one accountable partner.
- Not hourly billing as the default model: recurring retainer or clearly scoped day-rate missions with a written mandate.
- Not a deck-only consultant: I structure, challenge, and deliver (architecture, product, and code when it matters).
- Not a ticket-taker developer: I own outcomes, system coherence, and technical decisions tied to product goals.
- Not replacing your internal tech lead for day-to-day team management or sprint ownership.
- Not recruiting or running long interview rounds on your behalf.
- Not multi-day organization-wide training programs.
- Out-of-scope emergencies outside the shared urgency frame (scope, priority, response time).
- Mandates without a written scope or defined end date.
- Not MLOps, model training, GPU pipelines, or ML infrastructure operations: product-side AI usage, guardrails, and LLM API integration only.
- Not publishing public rate cards or monthly totals online: scope and pricing are agreed in writing before engagement.
- Not WordPress maintenance, plugin-only optimization, or cheap brochure-site retainers: editorial product platforms and fractional product-tech mandates only.

## Responsible AI usage

Luc uses AI to accelerate well-defined execution (boilerplate, refactors, tests, documentation) with human review, CI/CD guardrails, and architectural judgment. AI does not replace system design, API contracts, build-vs-buy decisions, or production sign-off. Nothing ships without human verification. Product AI engagements cover scope, prerequisites, risks, guardrails, build vs buy, and LLM API integration (Claude, OpenAI, etc.), not MLOps or model operations.

Each situation page describes a specific client context, approach, and engagement shape. Pages open with an H1 title, a short client-voice quote (epigraph), then the offer lede. Use headline, client voice, and summary for matching rather than inferring from generic "consultant" labels.
