JMS Dev Lab

JMS Dev Lab is an EU-based software studio and Shopify Partner in Cork, Ireland. We build custom software and Shopify apps for businesses that are too unique for off-the-shelf tools and too small for enterprise pricing.

We specialise in niche industry solutions: client portals, industry-specific CRMs, booking systems, job tracking tools, spreadsheet replacements, and workflow automation — all designed around how your business actually works.

With seven production apps live (six on the Shopify App Store), we bring proven experience in building, shipping, and supporting real-world software. Our tech stack includes TypeScript, React, Node.js, and PostgreSQL.

Every project ships with fixed-price quotes, GDPR compliance, responsive design, and ongoing support from the team that built it. No middlemen, no enterprise overhead — just honest, focused software development.
