How we work

A Clear Process. No Surprises.

Five steps from first call to long-term support — so you always know where your project stands.

  1. 01

    Discovery

    We learn your business, users and goals, then agree on scope, timeline and architecture.

  2. 02

    Prototyping

    Clickable Figma designs or an AI-assisted prototype — you see it before we build it.

  3. 03

    Development

    Short sprints with a progress update every week. No black boxes.

  4. 04

    QA & Testing

    Automated and manual testing, so what ships is stable, secure and fast.

  5. 05

    Launch & Support

    CI/CD launch, then monitoring, support and continuous improvement.

Security & AI ethics

Enterprise-Grade Data Security

Your data is your competitive edge. We protect it in every AI project and every line of code.

We never use client data to train AI models without your explicit permission.

Your data stays yours

Full ownership of your data, code and infrastructure — no lock-in.

No training on your data

Client data is never used for model training without your consent.

Private AI deployments

Run AI on your own cloud infrastructure when data must stay inside your walls.

Security-first engineering

Access control, secure coding and code reviews built in from the first sprint.

Technology

No Lock-In. Any Stack.

We're not tied to one framework. We pick what fits your product, your team and your budget — or pick up the stack you already run.

Frontend & mobile
React Next.js Vue Nuxt Angular Svelte TypeScript Tailwind CSS Flutter React Native Swift Kotlin
Backend & data
Node.js Python FastAPI Django Laravel .NET Go Spring PostgreSQL MySQL MongoDB Redis GraphQL
AI, cloud & automation
OpenAI Claude Gemini LangChain Hugging Face AWS Google Cloud Azure Docker Kubernetes Vercel Firebase n8n Make.com Zapier

40+ technologies and counting. Don't see yours? We work with that too.
