Mobile MVP with sign-in
React Native app (iOS/Android) with Expo, auth, a REST or GraphQL API, and a lean admin or web portal in Next.js — including store prep and CI for test builds.

Freelance app development & how to engage
If you want to build an app, run a server, or ship a website with real product value, I work with SMEs across the DACH region as a senior freelancer — from discovery to stable operations. High quality, direct and personal: one point of contact who also ships the code.
Stack & services
Typical work: React Native/Expo for iOS and Android, Next.js for web apps and marketing sites, Node.js with PostgreSQL or Supabase for APIs and data, and AWS or similar cloud services when scale and cost justify it. That keeps website, app, and backend aligned and maintainable by your team later.
Good fit
A strong fit when you want a clearly scoped app engagement (or help defining one), are comfortable with remote collaboration, and care about readable code, tests, and handover — software that stays maintainable after launch.
Process
- Intro call (goals, risks, rough budget)
- Proposal with milestones and clear deliverables
- Delivery with reviews — you stay in the loop
- Go-live, basic monitoring, and documentation for your team

Example scopes
Web app + server for an internal tool
Next.js UI, PostgreSQL or Supabase, roles and permissions, exports or integrations to your existing systems — focus on clear data models instead of feature sprawl.
Ongoing development
Retainer after go-live: bug fixes, small features, performance and dependency updates on an existing codebase — with fixed review cadence and transparent hour budgets.
FAQ
How do I get an app built — what is the first step?
A short intro call on goals, audience, budget range, and timeline. Then we align scope (MVP vs. later phases), technology (for example React Native/Expo for mobile), and how website, backend, and app should fit together. You receive a written proposal with milestones.
I want an app — do I need a website first?
Not necessarily. Many projects start with the app or a web app; sometimes a marketing site is added. What matters is which surface your users see first and where you route leads or support — we decide that together.
Can I commission website, backend, and app from one person?
Yes. Typical stacks are Next.js for the web, Node/PostgreSQL or Supabase for APIs and data, and React Native/Expo for iOS/Android — one coherent stack helps with auth, data models, and operations.
What does it cost to develop an app?
Cost depends on scope, platforms (iOS only vs. iOS+Android), backend, integrations, and maintenance. After the intro call you get a clear scope estimate and proposal — no one-size-fits-all numbers that would mislead you.
Freelancer or agency for app development?
A freelancer fits when you want to work directly with the person who builds the product — fewer handoffs, faster decisions. Agencies help when you need a large permanent team or many specialised roles. I work as a senior freelancer for SMEs.
Do you work remote only?
Mostly remote, with straightforward time zones for DACH and EU. On-site workshops or meetings can be arranged if needed — the focus is efficient collaboration.
How do I hire you in practice?
By email or by booking a calendar slot. We clarify requirements, I send a proposal and timeline; after approval, delivery runs with fixed review checkpoints until handover.
Which technologies do you use for app and backend?
Mobile: React Native with Expo; web: Next.js; backend: Node.js, PostgreSQL, Prisma or Supabase, plus AWS (Lambda, S3) and Stripe where appropriate — always matched to your budget and in-house skills.
