About us
We are a Budapest-based software team. We build systems for SMEs that fit daily operations — not just demos that look good on slides.
What we focus on
We are not here to ship the longest feature list. We build the solution that reduces manual work, clarifies processes, and stays maintainable years later.
Quality without compromise
Code review, automated tests and thoughtful architecture in every project — because software is only good if it can still be extended safely later.
A real partnership
We work as partners, not vendors: we think with you about business goals and speak up when something is worth doing differently.
Modern technology, common sense
We use proven, up-to-date tools — technology choices follow the needs of the project, not the hype cycle.
Our standard
Quality you can rely on
Not a promise — a practice applied to every project.
Code review
Nothing is merged unreviewed; the architecture is documented and readable.
CI/CD & safe releases
Automated pipelines, versioning and rollback-safe deploys.
Security by design
Encryption, access control and auditable operations as a baseline, not an afterthought.
Data protection / GDPR
Data minimisation, transparent processing and documented compliance.
Monitoring & support
After go-live too: monitoring, fixes and continuous development.
Services
Our services
We go deep in three areas: web systems, mobile apps and custom business software. What they share is careful design and maintainable delivery.
Web development
We build business web applications and portals that are fast, clear and extendable over time. Our stack is React, Next.js and TypeScript — SSR/SSG where SEO or first load matters, SPA where application UX comes first.
- Performance- and SEO-aware architecture with measurable Core Web Vitals goals
- Accessible, responsive interfaces for desktop and mobile use
- Admin / CMS surfaces or headless content management as needed
- Operational handover: logging, error tracking and release process

Mobile applications
We build cross-platform mobile apps with React Native or Flutter — native-feeling UI, reliable offline behaviour, and workflows people will actually use in the field.
- iOS and Android from one codebase, with platform-specific polish
- Push notifications, biometric login and offline-first data handling
- Backend integration (REST / GraphQL) and real-time sync
- Automated build and store release pipeline (CI/CD)

Custom software
When off-the-shelf software is not flexible enough, we build systems around your processes: ERP integrations, internal portals, dispatch tools, B2B ordering — software that fits how you already work.
- Domain modelling and API design aligned to business workflows
- Reliable data layer, access control and auditable operations
- Integration with existing ERP / back-office systems
- Security by design: authentication, encryption and roles

Approach
What you can expect
It is not about volume. It is about bringing the same discipline, transparency and ownership to every engagement.
Transparent collaboration
Weekly status, a shared backlog and agreed decision points. You always know where the project stands, what is next, and why.
Engineering quality
Code review, automated tests and documented architecture. We write code that can be extended safely later — with us or with another team.
Business focus
We understand processes and goals first. Technology follows that — not the other way around. If a simpler path is better, we say so.
Long-term ownership
We stay available after handover: operations, fixes and further development. The full lifecycle can stay in one place if you want it that way.
Portfolio
Case studies
Detailed case studies — from the starting point through the solution to the outcome. Not a list of logos, but how we work in practice.
Ways to work together
How we can work together
Choose what fits your goal — from a fixed-deadline project to continuous growth.
Fixed price
A project with a deadline
A defined scope, an agreed quote and a predictable schedule. Ideal when you know exactly what you want built.
Retainer
Monthly maintenance & development
Within a fixed monthly budget we develop, monitor and fix. Your system stays current and reliable.
Partnership
Long-term development partner
Aligned to your goals we plan, prioritise and deliver in iterations — a product that keeps improving together.
Let’s talk about your project
In a short, no-obligation conversation we map your goals and give an honest view of feasibility, timeline and likely scope.
We usually reply within one business day
