Leaf R&D is a Montreal-based engineering consultancy. We partner with startups and enterprises to design, build, and ship complex technical systems — from production web applications to autonomous drones.
We take on technically challenging problems across the full engineering stack — from frontend interfaces and backend APIs to AI pipelines, embedded systems, and hardware integration.
Our approach is pragmatic: we focus on shipping working systems that are maintainable, secure, and built to scale — without over-engineering for hypothetical future needs.
Security is built in from day one — not bolted on at the end. We follow OWASP standards and design for threat models from the start.
We choose the right tool for the job, not the trendiest one. Complexity is added only when it earns its keep.
No black boxes. You always know where things stand, what decisions were made, and why.
We treat your project as if it were our own. Deadlines, quality, and trade-offs are taken seriously.
From database schema to deployment pipeline, we handle the whole system — no hand-offs, no gaps.
We write code that's easy to maintain and extend. Your future team will thank us.
