What I'm looking for

I seek senior engineering roles where I can lead technical initiatives, mentor teams, work with cloud-native stacks, and deliver scalable, high-quality products in an agile environment.

I am a Senior Full-Stack Engineer with eight years of experience designing and deploying scalable web and mobile applications. I specialize in modern frontend frameworks (Angular, React, Next.js, Vue.js) and backend technologies (Node.js, FastAPI, Spring Boot), and I have led teams, mentored junior developers, and delivered measurable improvements in performance and user engagement.

I have a strong track record in cloud-native architectures across AWS, Azure, and GCP, microservices and serverless migrations, CI/CD automation with Docker and GitHub Actions, and improving product metrics such as engagement, responsiveness, and cost efficiency. I bring an agile mindset, emphasis on test coverage and security, and experience integrating complex APIs and real-time features to drive business outcomes.
