About Eleazar
Senior Angular Engineer with 5+ years of experience building scalable, modular frontend systems for large-scale enterprise applications.
I specialize in Angular (Nx, NgRx, Signals, RxJS) and help teams design maintainable architectures, refactor existing codebases and deliver complex features in production environments.
I work independently, join projects quickly and contribute from day one — no onboarding friction.
I help teams work with existing Angular applications: fixing issues, improving performance and refactoring legacy code without breaking production systems.
Available for remote freelance collaborations: architecture reviews, complex feature development, refactoring and technical consulting.
