ZMDevs

We design and build web and mobile products for startups and growing companies. Our engineering team is in Argentina and works on US hours, so you get senior work in your time zone and answers the same day.

What we do:

• Web apps — React, Next.js, Node.js, NestJS, TypeScript
• Mobile apps — React Native and Flutter, shipped to the App Store and Google Play
• E-commerce — custom storefronts, payments, admin panels
• APIs and integrations — REST APIs, payment gateways, WhatsApp Business
• UX/UI design — from wireframes to the finished interface

How you can hire us:

• Fixed-scope project — we start with a paid 1–2 week Discovery and give you a quote with defined scope and timeline
• Dedicated team — full-time developers who join your team and are billed monthly, minimum 3 months
• Support and maintenance — a monthly retainer after launch

Some of what we've shipped:

• Battersea House (UK) — online tutoring platform
• SharePass (Australia) — product for sharing passwords and sensitive data through links that expire
• Kivo (Argentina) — wholesale and retail e-commerce: web store, iOS and Android apps, admin panel
• Lovelia (Argentina) — online store, from storefront to checkout
• Aldo AI (Argentina) — AI assistant that answers WhatsApp for small businesses

We work in English, on US hours, and we tell you when something will not work instead of billing hours against it.

Tell us what you're building and we'll come back with how we'd approach it.
