Custom Software Development

When AI tools hit their limits, I build the missing piece.

Sound familiar?

When workarounds become the norm, it's time for a solution that truly fits your processes.

Processes stuck in Excel and email

Workarounds, manual data transfers, nobody can keep track anymore. Daily work takes more time than it should.

Standard software doesn't fit

SaaS tools force your processes into their structure. You work around the software instead of with it.

Custom software seemed unaffordable

Traditional software development was often too expensive for SMBs. That has fundamentally changed.

Why Custom Software?

Off-the-shelf software covers 80% of requirements, but the remaining 20% often make the decisive difference. When your processes are unique, you need software that's equally unique. I build solutions that fit your business exactly, not the other way around.

80%Standard20%machen den Unterschied
Architecture-First

Clean architecture decisions before the first line of code: that's the difference between software that works and software that grows with you. I think the structure through upfront, so you can focus on your business.

What does that look like in practice? Read the article

Service Spectrum

From web apps to cloud migrations, individually designed and delivered end-to-end.

Web Applications

Modern, responsive applications with React, Next.js, and TypeScript. From idea to production.

Cloud Architectures

Scalable infrastructure on AWS, Azure, or Google Cloud. Cost-effective and future-proof.

API Design & Integration

Clean REST and GraphQL APIs to connect your systems, internally and with external partners.

System Integration

Intelligently connect existing systems: CRM, ERP, third-party tools. Data flows instead of manual transfers.

Legacy Modernization

Gradually renew outdated systems without risking ongoing operations.

Technologies

I rely on proven, modern technologies, always with an eye on maintainability and longevity:

  • Frontend: React, Next.js, TypeScript, Tailwind CSS
  • Backend: Node.js, Java/Spring Boot, Python
  • Cloud: AWS, Azure, Google Cloud
  • Databases: PostgreSQL, MongoDB, Redis
  • DevOps: Docker, GitHub Actions, Terraform

Typical Projects

  • Customer portal with custom workflows and role-based access
  • Automated data processing with AI support
  • Migration of a legacy application to a modern cloud architecture
  • API platform for connecting external partners and systems
  • Dashboard and reporting solution for management decisions

How It Works

1

Describe Your Situation

We discuss your requirements, goals, and constraints. Eye-to-eye.

2

Concept & Architecture

I create a technical concept with clear architecture, timeline, and transparent cost estimate.

3

Agile Development

Development in short iterations with regular demos. You always see where we stand. And after the first milestone, you decide whether to continue.

4

Handover & Support

Clean documentation, deployment, and onboarding. After that, I'm here for support and further development.

Premium Quality. SMB Prices. No Contradiction.

AI-generated code has a bad reputation. Understandably: when assembled without architectural understanding, the results speak for themselves. But used correctly, AI isn't a replacement for expertise. It's an amplifier.

I've built my own highly efficient development processes that strategically integrate AI into every step: from requirements analysis through architecture to testing. Architecture decisions, code reviews, and quality assurance remain entirely with me. AI accelerates the implementation.

The result: software at a quality level that was previously only achievable with enterprise budgets, at prices that are realistic for small businesses.

How AI-assisted development makes software affordable

What's behind the hype, why quality standards still apply, and how custom software pays off for small businesses.

Who's behind it

Over a decade of experience in software architecture: from enterprise systems to lean solutions for small businesses. I bring the methods of large projects without the overhead.

As a freelancer, I know my clients' reality firsthand: limited budgets, tight timelines, no internal dev team. Every solution I build has to work under these conditions.

Good architecture isn't a luxury. It's the reason software is still extensible two years later.

Freelance Architect vs. In-House

Now you know who's behind it. The remaining question: does an external architect make more sense than an in-house solution?

With a Freelance Architect

  • Flexibly available exactly when you need me
  • No recruiting, no overhead, no onboarding
  • Instantly available expertise in software architecture and AI
  • Tailored precisely to your project
  • Transparent billing without fixed costs

In-House Solution

  • Lengthy recruiting process for specialized profiles
  • Fixed costs regardless of project workload
  • Ramp-up time for architecture and technologies
  • Additional management and administrative overhead
  • Less flexibility with changing requirements

Both approaches have their place. For project-based architecture expertise, the freelancer approach is often the more efficient path.

Is this right for your project?

So we both know from the start whether it's a fit.

Right for you

  • You want professional software without needing an enterprise budget
  • Your project is too unique for standard SaaS, but a traditional agency would be too expensive
  • You value short paths: one point of contact from concept to deployment
  • You want software that's cleanly built and can evolve over time
  • You're looking for someone who thinks along, not just executes requirements

Not the right fit

  • Your project needs a team of 10+ developers simultaneously
  • You need 24/7 managed hosting with SLA guarantees
  • You're looking for a pure template website without custom logic
  • You need someone on-site in your office (remote-first collaboration)

Happy to recommend the right partners for these topics.

depending on scope and complexity

After your inquiry, you'll receive a transparent estimate. The first milestone is your proof of concept: we only continue once you're convinced.
