Description

Senior software engineer with nearly 30 years of experience in frontend and web application development. I specialize in Angular, enterprise frontend architecture, NgRx, performance optimization, PHP systems, and AI-assisted software delivery.

I help companies stabilize complex products, improve scalability, reduce architectural risk, and move large applications forward when development becomes slow, fragile, or difficult to maintain.

My background includes enterprise B2B platforms, scheduling and workforce tools, admin systems, e-commerce solutions, CMS-based platforms, legacy modernization, and custom business software. I work hands-on as a senior developer or technical partner, with strong focus on real production problems, maintainability, and delivery quality.
