Vishal Gandhi - Lead iOS Engineer

About Me

I build iOS applications that serve millions of users. Over 12+ years, I've shipped apps at scale, led architecture migrations across 50+ modules, and mentored 15+ engineers into high-performing teams. My work spans the full stack of mobile engineering: from protocol-oriented payment systems and CI/CD pipelines to performance optimization that cut crash rates by 35%.

Currently, I lead iOS development for Mrsool, a regional delivery platform with 10M+ downloads and 100K+ daily users. I also maintain open-source Swift libraries for payment integration, code generation, and performance profiling.

What Colleagues Say

Vishal consistently delivers high-quality architecture decisions. His migration of our iOS app to Clean Architecture was methodical and had zero impact on our release schedule.

Engineering Manager

Mrsool

One of the strongest iOS engineers I've worked with. Vishal's payment integration framework saved us months of development time and significantly improved our transaction success rates.

Senior Product Manager

Mrsool

Vishal mentored me from junior to mid-level in under a year. His code reviews are thorough and educational — he doesn't just catch bugs, he teaches you why the alternative is better.
