At Mercor, I develop native iOS features and evaluate AI-generated technical solutions, including Swift and Objective-C code. I also assess LLM responses and contribute structured feedback for model improvement.

At Nordic Bedrift (Norway), I improved app performance by around 30% and reduced crash rates by approximately 25% through optimization, memory management, debugging, and error-handling improvements.

Across roles at Systems Limited, Digitify, Rockville Technologies, and other teams, I worked on payment and wallet flows, ecommerce features, and connected-device applications. My experience also includes custom video players for OTT platforms and iOS apps for streaming, fintech, and digital payments.
