What I'm looking for

I am looking for a collaborative environment that fosters growth, innovation, and the opportunity to work on impactful projects.

I am an iOS Developer with over 2 years of freelance experience, dedicated to enhancing and maintaining iOS applications. My journey has been marked by a commitment to delivering high-quality solutions, integrating RESTful APIs, and collaborating effectively with clients in asynchronous environments. I take pride in my ability to improve user experiences through UI enhancements and performance tuning.

Throughout my freelance career, I have developed and maintained iOS applications using Swift, focusing on writing clean, reusable, and efficient code. My experience with Git for version control has allowed me to manage feature branches and collaborate seamlessly with other developers. I thrive in remote work settings, where I can autonomously manage my priorities and deliver technical solutions on time.

In addition to my technical skills, I have a background in digital marketing and sales, which has equipped me with strong organizational and communication skills. I am currently pursuing a Bachelor’s in Computer Science, further solidifying my foundational knowledge in algorithms and object-oriented programming. I am eager to contribute my skills and passion for iOS development to a dynamic team.
