Web application, mobile app and SaaS development

Web and mobile app development, customer portals, dashboards, SaaS products and startup MVPs in React, Angular, Node.js and Python. Discovery to production.

Let's talk about your projectWhatsApp

A good application is more than well-designed screens: it needs a stable backend, correct permissions, data that stays in sync and performance that holds up as usage grows. AC builds web and mobile applications end to end and designs them to run reliably in production.

What we build

  • Web applications: management systems, customer portals, self-service areas and dashboards.
  • Mobile apps: for customers or field teams, sharing the same backend as the web system.
  • SaaS products: multi-tenant platforms with organizations, users, roles and permissions, serving many customers on shared infrastructure.
  • MVPs for startups: a focused first version that proves the idea with users, without overbuilding.

Building an MVP you will not have to rebuild

A common mistake is choosing between fast and right. You can have both if you are clear about what stays out of the first version. We start from the core value and the first user, defer everything that can wait, and get the hard-to-change foundations right: the data model, permissions, security and infrastructure.

SaaS: decisions to make early

A few SaaS decisions are very hard to change later: how tenant data is separated, how permissions work and whether tenants need their own customizations or integrations. AC's founder, Adir Cohen, has led the architecture of a multi-tenant B2B platform serving 60+ businesses since 2016, and that experience shapes every SaaS product we design.

Technology

React and Angular with TypeScript, Node.js and Python (FastAPI, Django), PostgreSQL and MongoDB, WebSockets and RabbitMQ for real-time needs, and Docker with GitHub Actions for delivery.

Most business applications need to integrate with other systems, so integrations are part of the specification from the start. Read about ERP integrations and custom business systems, or tell us about your project.

Frequently asked questions

What is the difference between an MVP and a full product?

An MVP is the smallest version that proves the core value with real users. It includes only what is essential, but it is built so you can keep developing on top of it rather than rebuilding it.

Do you build mobile apps too?

Yes. We build mobile apps for customers and field teams that share the same backend and data as the web system.

Which technologies do you use?

Mostly React and Angular with TypeScript on the frontend, Node.js and Python (FastAPI, Django) on the backend, and PostgreSQL or MongoDB for data. The choice depends on the project and on the team that will maintain it.

Can you take over an existing project?

Yes. We start with a review of the code, architecture and infrastructure, and decide together what to stabilize, what to rewrite and what to keep.
