Internal Tools & Dashboards
Custom admin tools, dashboards, and internal systems for process control, data visibility, and more efficient team workflows.
What I Build
I design and develop custom web applications and digital business software for demanding requirements — built on a foundation of clarity, scalability, security, and long-term maintainability.
Client Portals & SaaS Platforms
Scalable portals and multi-tenant SaaS solutions with authentication, role management, self-service features, and clean tenant separation.
Workflow Automation
Digital workflows and automated processes that reduce manual work, minimize errors, and save time in day-to-day operations.
API-Driven Backends
Robust backends and interfaces based on REST or GraphQL — providing a reliable foundation for web apps, mobile applications, and third-party systems.
E-Commerce & Ordering Systems
Custom ordering processes, online shops, and digital sales solutions with integration for payment providers, shipping services, and ERP or inventory systems.
Custom Business Websites
Professional business websites with a custom frontend, tailored backend, and dedicated admin panel — built for content, workflows, and future extensions.
Refactoring & Modernization
Technical restructuring and modernization of existing systems — with a clear migration path, cleaner architecture, and minimal disruption to operations.
More — e.g. Special Requests
Not every project fits into a standard category. Specific requirements, custom workflows, and unusual system ideas can also be planned and implemented in a focused way.
Architecture Built to Last
Every web app gets an architecture designed for long-term growth. No over-engineering at the start, but clear expansion paths.
Web today. Mobile tomorrow. Platform expansion when needed. — Built once. Intelligently extended.
Backend: Java Spring Boot / Node.js
Type-safe business logic with proven enterprise frameworks. Structured API endpoints for authentication, data processing, and business rules.
- Strong type safety
- Enterprise security
- Scalable REST API
- Long-term maintainability
Frontend: Vue / Nuxt / React
Modern, performant UIs with reactive frameworks. Clean separation from the backend via defined APIs.
- High-performance rendering
- Modular architecture
- SEO rendering (SSR/SSG)
- State management
Clean Separation
Frontend and backend are decoupled — UI redesigns don't require backend changes. Teams work independently.
Mobile-Ready
With API-first design, a mobile app can connect directly to the existing backend — no logic duplication.
Scalability
Third-party integrations, SaaS expansion, and microservice evolution — the system grows with you.
Enterprise Stability
Proven security concepts and long-term ecosystem support ensure operational stability.
Security & Compliance
Enterprise applications need more than good code — they need operational security and compliance from day one.
OWASP Top 10 Awareness
Development with awareness of the most common security risks — input validation, secure auth, XSS prevention.
GDPR & Data Privacy
Clear data separation, role-based access control, encryption, and data minimization.
Containers & CI/CD
Consistent environments, automated deployments, and version-controlled infrastructure.
Quality Assurance
Automated tests, code reviews, and dependency monitoring as integral parts of the process.
Technology Stack
I rely on proven, modern technologies. Selection is always project-specific — not trend-driven.
Java & Spring Boot
Enterprise-grade backend systems and APIs — scalable, stable, and built for long-term maintainability.
Vue & Nuxt
Modern frontends for reactive, high-performance, and user-friendly web applications.
SQL & NoSQL Databases
PostgreSQL, MariaDB, or MongoDB — selected based on data structure and project requirements.
APIs & Infrastructure
Integration of REST/GraphQL APIs, authentication systems, Docker, and cloud infrastructure for reliable systems.
Frequently Asked Questions
How long does web app development take?
It heavily depends on the scope. A lean MVP can be ready in 4–8 weeks. Complex platforms take several months. In an initial consultation, I provide a realistic estimate.
What does a web application cost?
It depends on the project. I offer transparent pricing models — from fixed prices to flexible hourly rates. In a free initial consultation, I discuss your budget and options.
Can existing systems be modernized?
Yes. I analyze existing code, identify technical debt, and create a clear migration path — without data loss.
Do you work with internal development teams?
Yes, I integrate seamlessly — whether as a complement to internal development or as a technical sparring partner.
Do you offer long-term support?
Yes — optional long-term support with individual monthly terms including updates, monitoring, and technical consulting.
What technologies do you use?
Proven technologies like Java Spring Boot, Vue/Nuxt.js, Node.js, React, SQL/NoSQL databases, and cloud deployment. Selection is always project-specific.
