Senior Freelance Software Engineer, IT Consultant and Tech Lead with 10+ years of experience in building scalable web applications, enterprise platforms, design systems, component libraries and AI-powered software solutions.

My core strength is turning complex product and business requirements into clean, maintainable and scalable software architectures. I have led frontend and full-stack initiatives in large enterprise environments, worked closely with product owners, designers, architects and stakeholders, and supported teams through technical leadership, code reviews, mentoring and agile delivery.

I specialize in modern frontend architecture, reusable component systems, design systems, web components, micro frontends, testing strategies, CI/CD optimization and high-quality TypeScript-based application development. I have built and improved applications used by large customer bases, implemented robust testing and release workflows, reduced build and test execution times, and established engineering standards across teams.

In addition to enterprise software engineering, I am currently focused on AI engineering, especially Voice AI automation, LLM-based workflows, AI agents and retrieval-augmented generation. I can support teams in designing and implementing AI-enabled products, automation workflows and intelligent user interfaces.

Typical areas where I can add value:
- Technical leadership for frontend, full-stack and platform projects
- Architecture design for scalable enterprise applications
- Development of design systems, component libraries and web components
- AI automation, Voice AI, LLM workflows, AI agents and RAG concepts
- React, Angular, Vue, TypeScript and Node.js development
- CI/CD, testing automation, code quality and developer productivity
- Mentoring, code reviews, agile delivery and stakeholder communication

I work hands-on, structured and outcome-oriented, with a strong focus on clean architecture, maintainable code, product quality and measurable business impact.
