Available to hire
Hi, I’m Igor Shulumba, a Senior Software Developer specializing in iOS/macOS with 11+ years of experience building, scaling, and mentoring teams for mobile-first solutions. I’m proficient in Swift and Objective-C, with backend expertise in Node.js, and I enjoy turning ideas into polished, scalable apps.
I love developing full-featured mobile applications from scratch, optimizing legacy systems, and sharing knowledge across teams. When I’m not coding, I stay curious by exploring new tech and mentoring others to grow their skills.
