What I'm looking for

I seek a remote position where I can leverage my fullstack development skills to create impactful software solutions while fostering a collaborative and innovative work culture.

I am a Senior Fullstack Developer with over 6 years of experience, focusing on ReactJS and NestJS. My journey has taken me through various projects where I have successfully designed and implemented software solutions for clients worldwide. I thrive in remote work environments and am passionate about enhancing user experiences through innovative technology.

Throughout my career, I have consistently improved application performance and user engagement. For instance, I translated a low-performing app from Flutter to React-Native, achieving a 70% improvement in performance and a 50% increase in user engagement. My commitment to quality is evident in my implementation of comprehensive testing and analytics, which reduced crash rates by 40% and enhanced code maintainability.

I am always eager to tackle new challenges and contribute to projects that align with my expertise. My goal is to continue leveraging my skills in a dynamic environment where I can make a significant impact on software development and user satisfaction.
