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 am a full stack developer and AI integration specialist building production-grade SaaS apps, chatbots, voice AI systems, and custom AI workflows on Node.js, React, AWS, Claude and OpenAI APIs. Most AI tools like Lovable, Replit, Bolt, Claude, Cursor get you 70% there. The last 30% is where projects die. I take over where those tools hit their limits, clean up the code, and ship a product that actually works in production. Here is what I build: ⚙️ Full Stack SaaS Applications End-to-end SaaS products on Node.js and AWS. Authentication, billing, dashboards, APIs, and everything between idea and a live product. 🔧 Vibe Code Rescue Your Lovable, Bolt, Cursor, or v0 build works as a demo but breaks in production. I take over, clean it up, and ship it properly. 🎙️ Voice AI Systems AI phone systems handling real customer interactions. Automated ordering, booking, and support that works without human intervention. 🤖 AI Chatbots Context-aware chatbots for SaaS, healthcare, and hospitality built with OpenAI, Claude, and Gemini. Production-ready from day one. ⚡ AI Automation & Workflow Systems Custom pipelines connecting your AI tools, APIs, and business logic into systems that run without manual intervention. Who I work best with: 🚀 Founders with a SaaS or AI product idea who need one senior developer to own the full build without gaps or handoffs. 🔥 Founders who built with Lovable, Bolt, or Cursor and need a real engineer to take it from demo to production. 🧩 Product teams whose existing app needs AI added properly. Not a quick API call. A real AI layer built to scale. I manage a structured delivery process. One point of contact. Full accountability. Senior oversight on every line that ships. How I work: 🔍 Discovery before code I understand your product goal and business logic before touching architecture. Most projects fail because this gets skipped. 🏗️ Architecture before development Full technical architecture defined and agreed before a single line is written. No surprises mid-build. 🎯 Milestone-based delivery Working builds at each stage. You test throughout, not just at the end. 🚢 Deployment included The job is not done until your product is live and working in production. For rescue projects: I start with a full codebase audit, tell you honestly what can be saved and what needs rebuilding, then execute clean. Recent work: ⚡ DocChief: Built the AI extraction layer and backend for a legal document intelligence platform now processing $250M+ in deal flow with 80% reduction in admin overhead. 🏨 HotelsByDay: Built the React Native mobile app for a day-use hotel marketplace with 7 consecutive quarters of growth. 📄 DocumentPro: Built the frontend for an AI document processing platform automating hundreds of invoices monthly across 50+ languages. 🔒 Active: AI mental health chatbot platform, 11+ months. Voice AI restaurant phone system, 6+ months. Both under NDA. $100K+ earned. 4,200+ hours. 100% Job Success. Top Rated. Clients stay for 6 to 11 months because the work actually delivers. Whether you are starting from scratch, stuck mid-build, or rescuing something an AI tool left unfinished, I am happy to take a look. Share the details and I will tell you honestly what is possible and how long it will take.
