What I'm looking for

I am looking for a role that challenges me technically and allows for mentorship opportunities while fostering a collaborative and innovative company culture.

As an iOS Principal Engineer with over 15 years of experience, I have a proven track record of delivering large-scale mobile solutions. My expertise lies in leading cross-functional teams and aligning technology strategies with business goals. I am passionate about mentoring teams to achieve high performance and fostering a collaborative environment.

Throughout my career, I have successfully consolidated multiple iOS apps into a single platform, safeguarding significant annual revenue. I have also contributed to architecture decisions and technical initiatives that enhance cross-domain collaboration. My hands-on experience includes writing code in Swift, Objective-C, and TypeScript, as well as optimizing CI/CD pipelines to improve build reliability and delivery cycles.

In addition to my technical skills, I have a strong background in cybersecurity and have delivered enterprise-grade iOS apps for major financial institutions. I am committed to continuous learning and sharing knowledge, as evidenced by my role as an Associate Teacher, where I taught iOS development to aspiring engineers.
