What I'm looking for

I’m looking for a fast-paced team where I can build user-centered products end-to-end, write clean scalable code, and keep learning. I value strong collaboration, ownership, and steady improvement from development through quality and support.

I’m a full-stack software developer with over 6 years of experience across front-end development, back-end systems, and quality assurance. I’m known for rapid learning, adaptability, and strong cross-functional collaboration, with a focus on clean, scalable code.

Recently, I built and maintained responsive React applications and worked closely with delivery and marketing teams to integrate components effectively. I also migrated and optimized production databases using AWS Cloud Services, improving reliability and reducing costs, and I supported users to reduce support tickets by 20%.

I’ve also delivered internal tools with PHP (Laravel) and deployed to Google Cloud Platform, leading performance optimization and cloud cost assessment that reduced infrastructure costs by 15%. I enjoy continuous learning and innovation, and I bring a practical mindset from QA and manual testing through to maintenance and production support.
