Web Application Development

Scalable SaaS, dashboards, and web apps with Next.js, Node.js, NestJS, and Laravel backends.

We build custom web applications — SaaS platforms, marketplace admin panels, internal tools — using modern, scalable stacks. Frontends in Next.js and React; backends in Node.js, NestJS, or PHP Laravel; data layers with PostgreSQL, MongoDB, and Redis. Deployed on AWS or Google Cloud with CI/CD pipelines built for growth.

Most products need more than an app. Every marketplace we have shipped runs on an operations layer nobody outside the company ever sees: the console where listings get approved, campaigns get priced, disputes get resolved and the numbers get read. That is the work on this page.

Onertrip pairs its Flutter app with a React web app and a Next.js admin console for users, ads, blogs, bookings and events. Oner Education runs four surfaces on one Firebase backend — a student app, a Next.js apply site, a React admin for catalogues and applications, and a separate Next.js CRM for agency partners. Auto-Listo! adds a self-serve B2B advertising module with admin approval and Stripe campaign payments in Mexican pesos.

We build these as real applications: role-based access, multi-tenant data models, audit-friendly workflows, and APIs that serve both your web and mobile clients from one source of truth. Deployment runs on Vercel, AWS or Google Cloud with CI/CD, so releases are routine rather than an event.

Our approach

How we decide what to build with

The trade-offs behind the stack, so you can challenge them before the work starts.

Next.js and React on the front

Server rendering where it helps SEO and first paint, client rendering where the product is an application. TypeScript throughout.

NestJS, Node.js or Laravel behind it

NestJS and Node.js for custom APIs and realtime workloads; Laravel where an admin-heavy product benefits from its ecosystem. Firebase when the product is better served by managed infrastructure.

A data layer chosen for the shape of the data

PostgreSQL for relational integrity, MongoDB for flexible documents, Redis for caching and queues, Firestore for realtime sync. We pick per product, not per habit.

Deployed and repeatable

Vercel, AWS or Google Cloud with Docker and CI/CD pipelines, environment separation, and deployments your own team can run after we hand over.

Who this is for

Where this service fits

If one of these sounds like your team, we have done this work before.

SaaS founders

A product with accounts, billing, permissions and a dashboard — built to handle a second customer as easily as the first.

Marketplace and app companies

You have an app live and are running operations out of spreadsheets and a Firebase console. You need a real admin surface.

Teams replacing internal tools

Manual processes held together by spreadsheets and email, ready to become software your team actually uses.

Products needing one API for many clients

A single backend serving an iOS app, an Android app, a web app and partners, without three divergent versions of the truth.

FAQ

Common Questions

Can you build both the mobile app and web admin?

Yes. Many projects pair a Flutter or React Native app with a Next.js admin panel backed by NestJS or Laravel — like SilverScore and our marketplace products.

What tech stack do you use for web apps?

Frontend: Next.js, React, TypeScript, Tailwind CSS. Backend: Node.js, NestJS, or PHP Laravel. Data: PostgreSQL, MongoDB, Redis, or Firebase. Payments: Stripe. Hosting: Vercel, AWS, or Google Cloud.

Can you integrate with our existing Laravel or Node backend?

Yes. We regularly extend existing Laravel, NestJS, and Node.js codebases — adding APIs, admin panels, or mobile client integrations without a full rewrite.

Can you build the admin panel for an app we already have?

Yes, and it is one of the most common things we are asked for. Onertrip and Auto-Listo! both pair an existing Flutter app with a Next.js admin console built against the same backend.

Do you build multi-tenant SaaS?

Yes. Multi-tenant data models, role-based access control and per-tenant configuration are standard parts of the work rather than add-ons.

REST or GraphQL?

Either. We design REST APIs by default because they are simpler to cache and debug, and use GraphQL where clients genuinely need to shape their own queries.

Where does it get hosted?

Vercel, AWS or Google Cloud, deployed into your own cloud accounts wherever you have them, so the infrastructure and its billing stay under your control.

Can you work with our existing backend?

Yes. We regularly extend existing Laravel, NestJS and Node.js codebases — adding APIs, admin panels or mobile client integrations without a full rewrite.
