Our development process

Így dolgozunk együtt – lépésről lépésre

We build software that works from ideas - tailored to your business processes.
Az AP4-nél a munka nem a kódolással kezdődik, hanem azzal, hogy megértjük, hogyan működik a vállalkozása, milyen célokat szeretne elérni, és milyen digitális akadályok lassítják jelenleg. Ezután következhet a tervezés, majd a fejlesztés – így jön létre egy olyan megoldás, amely valódi üzleti eredményeket hoz.

01

Consultation and needs assessment

Megértjük, mire van valóban szüksége – nemcsak technikailag, hanem üzletileg is.

02

Strategic planning

Közösen kijelöljük az üzleti célokat, technológiai irányokat és prioritásokat – így minden fejlesztés célzottan halad.

How are we different?

We only work with experienced developers

We don't do apprenticeships at the expense of the client - every project has a minimum of a senior or senior specialist.

We also take on projects left unfinished by others

We're not afraid of a challenge - we'll even clean up code left behind by previous developers.

We don't just program - we also think business

All developments are optimised for business purposes, so that we get a real return on what we build.

Agile, transparent operation

We work on a sprint basis, so you can see where we are at all times. There are no surprises.

You will own the source code

We have no hidden strings - what we develop is really yours.

Copyrighted source code

The source code becomes your property.

Our unique developments offer a solution for every business

Let us be your partner in building a digital future!

01

System modernisation

For small and medium-sized enterprises and large companies
If your existing systems are outdated, difficult to use or no longer keep pace with your needs, we replace them with modern, easy-to-use and well-integrated solutions. The goal: simpler operations, lower costs, better results.

02

Web and mobile apps

For startups and smaller businesses.
We develop digital platforms that are fast, intuitive and visually appealing - whether it's an MVP or a full-featured app. Ideal if you want to get to market quickly and offer a great user experience.

03

Robust enterprise systems

For large companies
Automation of internal processes, data management, scalable architectures - all based on individual needs. We help you optimise operations, reduce costs and increase competitiveness.

04

Self-service portals

For SMEs and larger companies
We can help you create customer portals that enable your customers to manage their own affairs - quickly, easily, anytime. This is not only convenient, but also significantly reduces the customer service burden.

05

MVP development

For startups
We help you to quickly implement a first version (MVP) based on the most essential features. This way you can get feedback from the market, convince investors and respond to real needs as quickly as possible.
