What I'm looking for

I seek senior engineering roles where I can lead end-to-end projects, mentor teams, apply clean architecture and TDD, and build scalable, high-availability systems in cloud environments with strong emphasis on code quality and continuous delivery.

I am a Senior Full-Stack Engineer with 10+ years delivering large-scale custom applications across Fintech, Healthcare, and SaaS engagements, owning projects from concept through production and long-term support.

I specialize in modern Angular (14+/17+) front-ends with NgRx/RxJS and TypeScript, and backend services in Node.js (NestJS, Express.js), designing microservices on AWS and Azure, improving performance (up to 40%), and implementing CI/CD and automated testing.

I champion SOLID and Clean Architecture, promote TDD and code quality standards, mentor engineering teams, and produce documentation and training to ensure maintainable, high-availability systems.
