What I do

Services

From first sketch to production deploy — clean code, a deliberate architecture and performance that is measured, not promised.

  • Single Page Applications

    Fluid apps in React, Next.js and Angular, with instant navigation, well-organized state and reusable components. Interfaces that respond immediately, with no full page reloads.

    • React, Next.js and Angular
    • Responsive and accessible design
    • Server rendering whenever SEO requires it

  • SEO-optimized websites

    Marketing sites and landing pages built to be found: semantic HTML, structured data, green Core Web Vitals and content that is indexable on first paint.

    • Technical SEO: sitemap, robots, canonical and hreflang
    • Schema.org structured data (JSON-LD)
    • Core Web Vitals and real-world performance

  • Web apps and APIs

    End-to-end systems: a .NET Core or Node.js back end, a carefully modeled relational database, REST and GraphQL APIs, microservices and messaging.

    • .NET Core, Node.js, Entity Framework
    • SQL Server, PostgreSQL and MySQL
    • Clean Architecture, SOLID and automated tests

  • AI service automation

    I wire language models into your processes: automated customer support, document extraction and classification, content generation and internal routines that run on their own.

    • Integration with generative AI APIs
    • Automation of repetitive workflows
    • Smart search over your own documents
