What I'm looking for

I seek a role where I can modernize iOS codebases, deliver measurable product impact, mentor engineers, and work in a collaborative, product-driven team.

I am an iOS developer with over seven years of commercial experience delivering production applications across distributed and multicultural teams. I specialize in full-cycle development—from product requirements through automated releases—focusing on stability, performance, and high test coverage.

I have led major modernization efforts, migrated codebases to newer Swift versions, introduced async/await patterns, and replaced legacy testing with modern SwiftTesting to raise crash-free rates and improve maintainability. I’ve shipped features that increased key metrics, including a loan flow that boosted issued loans by 34.6% and App Store rating improvements.

I actively mentor junior developers through code reviews and training, build independent products for the global App Store market, and enjoy solving architecture and performance challenges while ensuring reliable CI/CD and release automation.
