About

Professional summary

I am a Senior Full Stack Developer with extensive experience building and maintaining complex web applications across frontend and backend systems. I specialize in JavaScript, TypeScript, Angular, Node.js, SQL, and serverless architectures.

I have led the architecture and delivery of enterprise frontend migrations, including the progressive replacement of a large HR platform with Angular 21 and PrimeNG 21. I am comfortable taking ownership of complex technical initiatives while maintaining compatibility with existing systems and workflows.

My full-stack background includes developing document-processing platforms, landing page builders, time-tracking applications, file-management systems, and restaurant-management software. I build user-focused interfaces while also designing APIs and backend functionality.

I have experience working with Angular, NestJS, Node.js, Spring Boot, Hibernate, PostgreSQL, Elasticsearch, Ruby on Rails, and Serverless Framework. I also use Git-based Agile workflows and focus on testing, debugging, deployment, and maintainable code.

I collaborate effectively with designers, analysts, and engineering teams to translate business needs into reliable features. I have worked directly with cybersecurity analysts and have consistently followed UX specifications and best practices.

I am based in Timisoara, Romania, and currently work remotely. I am an experienced independent contributor who can also work productively within collaborative product and engineering teams.
