Mayank Jangid
iOS Developer + HealthKit, CoreML, SceneKit, SwiftData, PassKit, and App Attest
I build native iOS apps in Swift. On-device ML, HealthKit pipelines, 3D scenes, and the platform frameworks that make an app feel like it belongs on the phone.

Hi there
I’m Mayank. I just graduated in 2026, and I’ve been building iOS apps in Swift since well before that. Since September 2025 I’ve been a founding developer at SkyClad Ventures, working on the iOS side of MedQT, a health-records app that’s live on the App Store. The other two projects here are ones I built for myself.
Native iOS with SwiftUI is where I’m happiest, especially the parts that sit close to the device: running a small model on-device, pulling something useful out of raw HealthKit samples, getting Blender assets into SceneKit. I also poke at Flutter, and I’m currently learning Go, mostly because it looks cool.
The thing I actually want to end up doing is AR/VR. I think spatial computing is going to change how interfaces work, and I’d love to build in that space one day, ideally as an indie developer. For now I’m learning my way toward it. If you’re working on something interesting, I’d like to hear about it.
