What we offer

## Software built for your business

We design and build web and mobile applications from scratch — or take over and improve existing
ones. Whether you need a customer-facing portal, an internal tool, or a complex e-commerce
platform, we deliver solid, maintainable software on time.

Our team covers the full stack: React, Next.js, Node.js, Python, .NET, PostgreSQL, and more. We
follow modern engineering practices — clean architecture, automated testing, CI/CD pipelines —
so you get code that works today and is easy to extend tomorrow.

Every project starts with a discovery phase where we understand your business, users, and goals.
This means no wasted effort — only features that matter.

### Web applications

Responsive, fast, and accessible web apps — from landing pages to complex SaaS
products.

### Mobile apps

Cross-platform mobile apps with React Native, or native iOS/Android when performance
demands it.

### API & integrations

RESTful and GraphQL APIs, third-party integrations, payment gateways, ERP connectors.

### E-commerce & portals

Custom e-commerce platforms, customer portals, and self-service tools built to convert.

How we work

## Agile delivery step by step

We use an agile approach with short delivery cycles so you see real progress every week — not
just
at the end.

1

### Discovery & planning

We define requirements, user stories, and architecture. You get a clear scope and
timeline.

2

### Design & prototyping

UX wireframes and interactive prototypes — so you can validate the product before a line
of code is written.

3

### Development & testing

Iterative sprints with demos every 2 weeks. Automated tests and code reviews built in
from day one.

4

### Launch & support

Deployment to production, monitoring setup, and ongoing support as you grow.

Case study

## Fleet management portal for logistics company

A logistics company with 300 vehicles needed a real-time fleet management portal to replace a legacy
spreadsheet-based process. We delivered a React + Node.js web app with live GPS tracking, driver
performance dashboards, and automated reporting in 4 months.

The portal reduced manual reporting work by 80 % and gave management real-time visibility into fleet
utilisation. The system now handles 10 000+ events per day with 99.9 % uptime.

✓ 4 months to delivery
✓ 80% less manual work
✓ 99.9% uptime
✓ 300 vehicles tracked
