Full Stack Developer for SaaS + Ecommerce Platform (Ongoing Work)

We're a UI/UX design agency working on a SaaS + ecommerce platform, and we need a developer on board early, while designs are still taking shape, rather than handed a finished file at the end. That means we want someone who'll push back. Who'll tell us what's expensive to build before we design it. Who has opinions on architecture and can explain them to a non-developer. No stack decided. That's a conversation, and we want to hear what you'd recommend and why. What we're looking for → Full stack, end to end → Strong opinions on architecture and system design, and the ability to explain them clearly → Comfortable joining client calls for technical consultation → Someone who tells us when something isn't sensible, instead of quietly building something worse Why this is worth your time: This starts with one project, but we have design work coming through regularly that needs development attached. We're looking for someone to build a long-term working relationship with, not to fill one job. To apply, please include: → A live URL of something you built end to end, and what your role was → How you'd approach deciding architecture for a platform like this → What you'd need from us before you could estimate anything
