I build native iOS and Android applications that work in the real world, in the field, offline, in complex physical environments where most mobile solutions fall apart. My focus is on technically demanding work: augmented reality and spatial computing, LiDAR-based 3D reconstruction and site scanning, RoomPlan-based room and space capture, GIS and GNSS field data collection, BLE and IoT device integration, and AI/ML features that actually ship. Not demos, production systems.
I'm the founder of Quality Wolves, a senior-only engineering team. Everyone on the team has owned full project cycles and made architectural decisions. We take ownership of the technical scope, surface what matters, and keep things moving. You stay focused on your product, we handle the build.
What I build:
Native Mobile: Swift, SwiftUI, Kotlin, full-cycle iOS & Android development, App Store and Google Play delivery
AR / Spatial Computing: ARKit, ARCore, RealityKit, RoomPlan, LiDAR scanning, point cloud processing, 3D reconstruction, Apple Vision Pro.
GIS & Field Data: GNSS/RTK integration, offline-first architecture, geospatial data pipelines, custom map layers, QGIS compatibility
AI & ML: LLM integration, computer vision, NLP, on-device inference with Core ML and TensorFlow Lite, OpenAI and custom model pipelines, TTS/STT
Connectivity: BLE pairing flows, LoRa, IoT sensor integration, background sync, beacon tracking
Our senior engineers use AI tools deliberately, not as a substitute for judgment, which means faster delivery without trading speed for technical debt.
Good fit if you:
Need someone who operates independently without hand-holding
Are building something with real operational complexity
Have been burned by teams that shipped demos and called it done
Describe the problem you're trying to solve, send a message, and let's talk specifics.

I build AR/VR experiences that are fast, stable, and visually clean.
Seven years in the field — prototypes, full products, games, training apps, geospatial tools, you name it.
My main strength is development, but I also handle the extra pieces: light 3D fixes, UI/UX design, analytics, builds, integrations, and store publishing. I move quickly, communicate clearly, and solve problems without drama.
Skills & experience:
- Unity (AR Foundation, Vuforia, OpenXR, Meta, Vision Pro)
- AR/VR apps, games, enterprise tools, training systems
- Firebase, Mixpanel,
- IAP(In-App purchase), Ad mediation (AdMob, IronSource)
- Maps, geospatial, VPS/Immersal
- Kinect & PC builds
- Figma UI → Unity
- API, JSON handling
- C# programming
If you need someone who can jump in, take ownership, and deliver without hand-holding — that’s me.
