Custom web applications built for businesses in the Dominican Republic — dashboards, booking systems, client portals, and internal tools built with Next.js and React.
A web application is the right solution when your business in the Dominican Republic has outgrown static websites and spreadsheets. If you're managing bookings manually, coordinating between teams through WhatsApp, or handling workflows that could be automated — a custom web app replaces all of that with a single, secure, purpose-built platform your whole team can use.
We build custom web applications using Next.js, React, TypeScript, and Firebase — the same stack behind Sertuin Events, a multilingual event planning web app we built that delivered 150% sales growth for our client. Every app we build includes secure user authentication, role-based access control, admin dashboards, and API integrations with the tools you already use — from payment gateways like PayPal and Stripe to CRM systems and email platforms.
From tour operators in Punta Cana needing real-time booking management, to companies in Santo Domingo digitizing internal approval workflows, to SaaS startups across the Dominican Republic building their first product — we scope, design, and build web applications that are fast, secure, and ready to scale from day one.
We've built custom web applications that delivered 150% sales growth for Dominican Republic clients — using Next.js, React, and Firebase to create platforms that are fast, secure, and built to scale.
Built around how your business actually operates — not forced into a template or off-the-shelf tool.
Built with TypeScript and Firebase for type-safe code, secure authentication, and infrastructure that scales without rebuilding.
Connect PayPal, Stripe, CRM systems, email platforms, WhatsApp, and any third-party service your business depends on.
Interfaces your team and customers will actually enjoy using — clear navigation, mobile-first, and tested before launch.
Live data updates, real-time notifications, and instant interactions — no page refreshes required.
Manage users, content, data, and settings from a clean admin interface — no developer needed for day-to-day operations.
Every web application we build includes these as standard — production-ready, secure, and fully documented.
Fully functional on desktop, tablet, and mobile — built mobile-first for the 70%+ of Dominican Republic users on smartphones.
Optimized meta tags, structured data, and page structure so public-facing parts of the app rank in Google from launch.
Sanity CMS connected so your team can update content, copy, and media without touching code.
Secure login system with role-based permissions — control exactly who can see, edit, or manage each part of the app.
Full app localization in English, Spanish, or additional languages — including per-language SEO and hreflang tags.
Stripe, PayPal, or custom checkout flows — secure payment processing built directly into your application.
A fully branded admin interface for managing users, data, permissions, and app settings beyond the standard CMS.
Our proven process ensures your project is delivered on time, on budget, and exceeds expectations.
We map your business processes, define the user roles, and document every feature requirement before writing a single line of code — so there are no surprises mid-project.
We design every screen — dashboards, user flows, forms, and mobile views — before development begins. You approve the design first, so the build phase has zero ambiguity.
We build your application with Next.js, TypeScript, and Firebase — implementing authentication, database logic, API integrations, and all custom features defined in discovery.
Every feature is tested across devices and browsers — user flows, edge cases, authentication, payments, and performance benchmarks all verified before you see the final build.
Deployment to production with environment configuration, DNS setup, Google Search Console verification, and final performance checks — your app goes live ready for real users.
Full walkthrough of the admin panel, CMS, and any management tools — so your team can run daily operations independently from day one. Documentation provided.
Got questions? We've got answers.
A web application is any browser-based platform that goes beyond displaying information — it lets users interact, log in, submit data, make payments, or manage content. Examples include booking systems, client portals, internal dashboards, event management platforms, SaaS tools, and inventory management systems. If your business process involves users doing something — not just reading — you likely need a web app.
Yes. Every web application includes Sanity CMS integration so you can update copy, images, and content from a simple dashboard without touching code. For data and user management, we also build a custom admin panel so your team has full operational control from day one.
Yes — mobile-first is our default approach. Every screen, form, and dashboard is designed and tested on smartphones and tablets before desktop. This is especially important for the Dominican Republic market where over 70% of users access the web from mobile devices.
Yes. Every project includes 30 days of post-launch support at no extra cost, plus 1 year of free hosting. After that, our maintenance plan at $95/month covers security monitoring, performance optimizations, uptime tracking, and priority bug fixes. For web applications specifically, we can also handle feature additions and updates on an hourly basis.
Yes. API integrations are a core part of every web application we build. We've integrated with PayPal, Stripe, Mailchimp, WhatsApp Business API, Google Workspace, HubSpot, and many others. During the discovery phase we map out all the tools your business currently uses and design the integration architecture before development begins.
Our primary stack is Next.js (React framework), TypeScript, Tailwind CSS, and Firebase for authentication and real-time data. For content management we use Sanity CMS. For email workflows we use Nodemailer or third-party providers. For payments we integrate Stripe or PayPal. This is the same stack we used to build Sertuin Events — a multilingual event planning web app that achieved 150% sales growth for our client.
