Full-stack software, from first idea to production.

I design, build and improve web products across interfaces, backend systems, AI integrations, performance, hosting and release delivery.

From the first interface to a reliable production setup, I cover the full build.

  1. Web & Full-Stack Development

    I build full-stack products, dashboards, webshops and internal tools around clear interfaces and dependable technical foundations. The stack follows the product, not the other way around.

    • Interface and backend implementation
    • APIs, auth and role-based access control
    • Database modeling and data integration
    • Real-time features with SSE and WebSockets
    • Admin dashboards, platforms and webshops
    • SaaS products and internal business tools
    • Framework selection based on product needs

  2. AI & LLM Integration

    I add practical AI where it makes a product more useful, from retrieval and streaming responses to tool-using agents connected to real workflow data.

    • Local and cloud LLM integration
    • Retrieval-Augmented Generation
    • Agentic tool-use loops
    • Streaming responses via Server-Sent Events
    • Connector abstractions for external data
    • Voice I/O, memory extraction and model routing

  3. Code Quality & Maintainability

    I strengthen existing and new codebases with TypeScript, focused testing and clear engineering standards, so they remain reliable and easier to extend.

    • TypeScript migration and strict mode setup
    • Type-safe API contracts and database queries
    • Unit and integration testing
    • End-to-end testing with Cypress
    • Linting, formatting and code standards
    • CI automation for test pipelines

  4. Performance & Web Vitals

    I improve real-world performance across rendering, bundles, assets and metadata, with Core Web Vitals guiding the work.

    • Core Web Vitals and Lighthouse optimization
    • Bundle analysis and code splitting
    • Image and asset optimization
    • Dynamic imports and lazy loading
    • Zero CLS and minimal TBT targets
    • SEO and structured metadata

  5. CI/CD & DevOps

    I set up the environments and automated pipelines that move software safely from development to production across Vercel, Azure and self-hosted VPS infrastructure.

    • Azure DevOps YAML pipeline setup
    • GitLab CI/CD pipelines
    • GitHub Actions workflows
    • Preview deployments with Vercel
    • Self-hosted VPS deployment and maintenance
    • Lighthouse CI in the pipeline
    • Secrets management and environment config
