What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a Senior Full Stack Mobile Engineer with over 7 years of experience specializing in building high-performance, user-focused applications. My expertise lies in leveraging technologies such as Python, NodeJS, and React Native to create scalable and intuitive interfaces. I have a proven track record of leading projects that enhance operational efficiency and reduce costs, such as consolidating multiple web applications into a single React Native app, which cut server costs by 50% and accelerated feature deployment.

Throughout my career, I have successfully transitioned monolithic applications to microservices, established CI/CD pipelines, and integrated third-party APIs to enhance functionality. My leadership experience includes managing teams and driving projects from conception to successful launch, ensuring that user feedback and performance metrics guide continuous improvement. I am passionate about utilizing technology to solve real-world problems and am always eager to take on new challenges that push the boundaries of innovation.
