01 LEAN Operations
LEAN Operations means: You focus on the business, we ensure the systems behind it run smoothly. 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 it can get stuck at any point.

02 LEAN Stability
LEAN Stability means: Your logins are secure, your systems communicate, your releases run smoothly, and your incidents have a plan. Your team can rely on the infrastructure.
Systems that hold up 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 rebuilding everything. Outdated frontends, decisions based on Excel sheets, 3 developer teams when one would suffice – sound familiar?

Frequently Asked Questions
[] 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 focus 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’s 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. Plus TypeScript, NestJS, GraphQL, Docker, and Kubernetes. For cross-platform mobile apps, we rely on Flutter – one codebase for iOS and Android. In frontend modernization, 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-driven 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 in energy, 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 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 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 software quality?
Automated testing and CI/CD pipelines are standard for us, not optional. Every release is automatically tested and rolled out securely. Additionally, we conduct code reviews in the team, monitoring during operation, and structured incident management processes. We build quality into the process – not as an afterthought.
[] Does LEAN-CODERS also develop accessible software?
Yes. Accessible app development and WCAG-compliant web development are part of our offerings. 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. Then we evaluate together: What worked, what was worthwhile? Once the proof is established, we scale – build the team, take responsibility, deliver 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 won’t receive a concept paper at the end, but a functioning result: 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 together at the results – what worked, what was worthwhile, 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 is convincing, we move to scale – your project grows, your team grows with it, and 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’s not a must. If you already know what you need and want to start directly, 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, with a second location in Zurich. Over 80% of our team are experienced senior developers. Very low turnover – this 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.
