No more quick fixes. We solve it properly.

01 LEAN operations

LEAN operations means: You focus on the business, we ensure that the systems behind it run. Your custom smooth operator, from Vienna, for the DACH region.

A lot happens between offer and revenue. Configure, calculate, onboard, check out, deliver content – and at every point, it can get stuck.

02 LEAN stability

LEAN stability means: Your logins are secure, your systems communicate with each other, your releases run without drama, and your incidents have a plan. Your team can rely on the infrastructure.

Systems that hold instead of breaking down. Every system is only as stable as its weakest interface.

03 LEAN evolution

LEAN evolution: You modernize your systems without jeopardizing operations. No big bang, no production stop – your business continues while the stack improves.

Old becomes new, but without building everything anew. Outdated frontends, decisions based on Excel spreadsheets, 3 developer teams where one would suffice – sound familiar?

Case studies

The most beautiful success stories of our customers

Less talk. More code. Here’s the result.

How your project runs

1. Pilot

Start your project as a pilot:

4–12 weeks. One problem. One solution that works.

No discovery document for the drawer – but a functioning result: MVP, prototype, or what was agreed upon in the discovery call.


Proof: Measure what matters.

Your KPIs show what works. You decide: scale, adjust, or take a different path.


2. Scale

Scale: Your project is ready for the next step.

Faster team building, lasting know-how. You are productive in weeks and independent in the long term.


Book a discovery call now – after that, you will have clarity about your pilot project.

OpenClaw, Industry Cloud Platforms, Low-Code/No-Code: not on our watchlist, but in our projects. Because further education is part of our daily routine, not an annual event.

What we stand for

Frequently asked questions

FAQs
What exactly does LEAN-CODERS do?

We are a software development company from Vienna. We build custom software for the DACH region – from CPQ systems to self-service portals to complete platforms. Build, run, improve: We develop, operate, and enhance your software. Everything from one source, no agency model.

Why does LEAN-CODERS rely on open source software development?

Because open source gives you independence. Lower licensing costs, full control over your code, no vendor lock-in. If you want to switch providers tomorrow, you can – because the code belongs to you. We use open source wherever it is the better solution. Data sovereignty and independence are not just marketing terms for us, but architectural decisions.

What technologies and frameworks do you use?

Our core stack: Angular, React, Node.js, Flutter, and Astro. Additionally, TypeScript, NestJS, GraphQL, Docker, and Kubernetes. For cross-platform mobile apps, we rely on Flutter – one codebase for iOS and Android. When modernizing frontends, we migrate existing systems to Angular or React. We build backend and infrastructure cloud-native on AWS, Azure, or GCP – or self-hosted with OpenShift, Dokploy, and Coolify. Your setup, your decision. And yes, we use AI-supported development in the engineering process – where it delivers real results.

For which companies is LEAN-CODERS the right partner?

For companies in the DACH region whose software can no longer keep up with the business. Typical starting point: legacy systems, technical debt, lack of scalability, stalled enterprise solutions, or complex internal calculations that need to be reliably represented. Whether energy industry, e-commerce, or industry – if your business is complex, we are the right fit.

What is the LEAN transformation of LEAN-CODERS?

Our LEAN transformation is a holistic system consisting of three domains. LEAN operations: systems for your daily business – CPQ, portals, payment gateway integration, headless CMS. LEAN stability: stable infrastructure – SSO integration, ERP/CRM connections, CI/CD pipelines, monitoring. LEAN evolution: modernizing existing systems – ML forecasting, FinOps, legacy UI modernization. No big bang, no production stop – step by step.

Does LEAN-CODERS also offer consulting and code reviews?

Yes. Our senior engineers provide honest advice – even if it means advising you against an idea. We offer software quality checks and code review services: focused sessions on your stack. Performance, security, accessibility, API health. You receive an honest report with actionable measures. No consultant jargon.

How does LEAN-CODERS ensure the quality of the software?

Automated testing and CI/CD pipelines are standard for us, not optional. Every release is automatically tested and securely rolled out. Additionally, code reviews in the team, monitoring in ongoing operations, and structured incident management processes. We build quality into the process – not as a retrospective check.

Does LEAN-CODERS also develop accessible software?

Yes. Accessible app development and WCAG-compliant web development are part of our offering. With the Accessibility Strengthening Act, digital accessibility becomes mandatory – we make it an integral part of the architecture. Audit, implementation, and testing from one source.

How does collaboration with LEAN-CODERS work?

Pilot → Proof → Scale. We start with a defined pilot (4–12 weeks), solve a specific problem, and deliver a functioning result. After that, we evaluate together: What worked, what was worth it? If the proof stands, we scale – build a team, take responsibility, deliver in the long term. Commercial model: Time & material, transparent, no fixed price risk.

What is the pilot phase?

A clearly defined project with a defined scope – typically 4–12 weeks. You receive a functioning result at the end, not a concept paper: real code, tested and deployed. The pilot shows you what we can do before you make a long-term decision.

What happens after the pilot phase?

After the pilot comes the proof: We look at the results together – what worked, what was worth it, where are the gaps? Everything measured against defined KPIs, not gut feeling. Based on this, you decide: scale, adjust, or stop. No pressure, no upselling. If the proof convinces, we go into scale – your project grows, your team grows with it, the knowledge stays with you.

Do I have to start with a pilot phase?

No. The pilot is our recommended entry point because it creates clarity for both sides – but it is not a must. If you already know what you need and want to get started right away, we can also join an ongoing project or start directly with a larger scope. We adapt to your pace.

Where is LEAN-CODERS located and how big is the team?

Headquartered in Vienna, second location in Zurich. Over 80% of our team are experienced senior devs. Very low turnover – which means: your contact person will still know your code in six months. We work in the DACH region, in your time zone, without offshore detours.
