What I'm looking for

I am looking for a dynamic work environment that fosters innovation and collaboration, where I can further develop my skills and contribute to impactful projects.

I am a passionate Full Stack Developer with a strong focus on building innovative applications using React Native and modern web technologies. My experience includes creating cross-platform apps with over 54 screens, optimizing performance, and enhancing user experience through responsive design and efficient coding practices.

At Xinacle, I successfully migrated our state management from Redux Thunk to Redux Toolkit, significantly improving our application's performance and maintainability. My ability to craft robust REST APIs and model complex backend entities has been instrumental in delivering high-quality software solutions. I thrive in collaborative environments and enjoy tackling challenging problems with creative solutions.

In addition to my development skills, I have a solid foundation in DevOps practices, having automated AWS deployments and designed CI/CD pipelines that streamline our development processes. I am always eager to learn and adapt, and I am excited about the opportunity to contribute to innovative projects that push the boundaries of technology.
