What we do

Senior engineering across the full stack

Java & Spring Backend

Robust server-side systems built with Java and Spring Boot — scalable APIs, business logic, database design, and backend architecture your business can rely on.

React Frontend

Clean, fast, responsive user interfaces built in React. From dashboards to customer-facing portals — interfaces that look great and perform on every device.

Full-stack Web Apps

End-to-end web application development — from database to UI. We handle the full product so you get one team accountable for everything.

API Integrations

Connect your systems with third-party services, ERPs, CRMs, or custom APIs. We design clean integrations that are reliable, documented, and maintainable.

Payment Systems

Stripe, PayPal, local payment gateways — we implement and integrate payment flows that are secure, compliant, and conversion-optimised for European markets.

Mobile-friendly Sites

Business websites and web apps built to perform on any screen. Fast, accessible, and designed to convert visitors into customers.

How it works

From first call to working software

No long contracts, no bloated teams, no surprises. GratiaSoft works in focused cycles so you see progress fast and stay in control throughout.

1

Discovery call

We talk through your project, goals, and constraints. No obligation, no sales pitch — just a clear understanding of what you need.

2

Proposal & scoping

You receive a clear proposal: what we build, how long it takes, and what it costs. Fixed-scope or retainer — your choice.

3

Build & iterate

We develop in short cycles with regular updates. You see working software early and can give feedback throughout.

4

Launch & support

We deploy, hand over, and stay on as your ongoing technical partner — bugs fixed, features added, systems maintained.
