About Me

Full Stack Software Developer with strong experience building scalable, high-quality applications across frontend and backend. Skilled in designing and implementing architectures with modern frameworks and deploying solutions in cloud and microservices environments.

Beyond coding, I am highly collaborative: I regularly conduct code reviews, refactor and optimize existing codebases, and work closely with QA teams to identify vulnerabilities, improve security, and raise overall software quality.

I thrive in agile environments, ensuring smooth communication between teams, and contributing to both technical excellence and project success.
