Overview
A custom web application, built around how you work
When a spreadsheet, emails and three apps are no longer enough, a custom web application brings your operations into one place. Web application development at Talgasy Web starts from your real processes: who does what, which data moves around, and what wastes your time today.
The result: a client portal, an internal tool or a dashboard available from any browser, on computer or phone, with the right access for each user. We build with modern web technologies such as React, Node.js and TypeScript.

What you get
What is included
Five deliverables included in every web application project, from the starting price.
- 01
Custom interface
Screens designed for your users and their tasks, not a generic template to work around. Every flow is built to get straight to the point.
- 02
Dashboard or client portal
Your clients follow their requests, documents or orders; your team sees what matters at a glance.
- 03
Database and business logic
Your business rules are built into the application: calculations, statuses, validations and history, with structured, reliable data.
- 04
Authentication and roles
Secure sign-in and role-based access: a client only sees their own information, a manager sees their team, an administrator sees everything.
- 05
Initial deployment
We put your web application online and support its launch, ready to be used by your team or your clients.
