iOS Developer and Founder of Maptur, a real-time motion capture platform that turns iPhones into 6DoF tracking devices for Blender. I build creative production tools that bridge hardware and software, shipping Swift and SwiftUI apps with ARKit, CoreMotion, and low-latency network streaming alongside Python add-ons for 3D workflows. 4+ years in advertising and media production across Medical, Tech, Automotive, Fashion, and VFX gave me a sharp eye for workflow problems worth solving. That experience now drives how I approach product development: lightweight tools, real pipelines, creator-first design. Background in live production systems (ATEM), studio networking, server infrastructure, and electronics design. I'm most at home where real-time data, hardware constraints, and polished UX collide. Currently shipping Maptur on the App Store. Open to iOS and creative tools roles.

I am a seasoned mobile application developer with over two decades of hands-on experience in crafting cutting-edge mobile solutions. My journey in the industry has seen the evolution of mobile technology, and I've consistently adapted and excelled in delivering top-notch mobile apps. Owner of Oval Innovations, LLC. Key Skills: iOS and Android Development Cross-Platform Development (React Native, Flutter) UI/UX Design and Optimization Backend Integration and API Development Quality Assurance and Testing Continuous Integration/Continuous Deployment (CI/CD) Project Management and Team Leadership

I've spent 11 years working with clients of all sizes across a lot of different industries. That breadth means I can adapt quickly to just about any app idea and pick up new domains fast. I know the grind of building out a first MVP and I know how to jump into an existing codebase and find the path of least resistance to get it fixed. Both sides of that equation. What I like most is looking at the long-term picture - planning different stages, thinking through feature releases, watching an app grow. Most of my best client relationships have lasted years because of that. It's good for them and honestly it represents stability for me too. That alignment tends to produce better work. If you're looking for someone to own the mobile side of your product and stick around, send me a message. — Quentin H.

I am a professional software developer with 25 years of experience. I focus on mobile app development for Android and iOS, web development, and cloud services. Throughout my career I have gained experience in many different technologies, from modern cloud, mobile, and web development architectures all the way back to mainframe systems. My app development experience includes location services, map integration, user authentication and user profile management, payment functionality, media playback including both audio and video, and in-app purchases. I can work with many services available from Amazon Web Services (AWS) and Google Cloud Platform (GCP). I am committed to producing a quality product. I always stand behind my work and communicate as much as I can. The more my client and I both know about what is being done, the happier everyone is.

I build and scale production-grade 𝗔𝗜, 𝗦𝗮𝗮𝗦, 𝗮𝗻𝗱 𝗳𝗶𝗻𝘁𝗲𝗰𝗵 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 that handle real users, real data, and real business constraints, not prototypes or proof-of-concepts. With 𝟭𝟯+ 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗳𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲, I work across backend architecture, frontend systems, cloud infrastructure, and AI integration to deliver platforms that are built for reliability, scalability, and long-term maintainability. 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝘁𝘆𝗽𝗶𝗰𝗮𝗹𝗹𝘆 𝗵𝗶𝗿𝗲 𝗺𝗲 𝘄𝗵𝗲𝗻: • They are building a SaaS or AI product that needs to scale beyond MVP • Their backend or architecture is becoming unstable under real usage • They need secure, production-ready fintech or payment systems • They are integrating AI into real workflows (not just chat demos) • They need senior-level ownership across full product delivery 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱: • AI-powered systems that automate real business workflows • Multi-tenant SaaS platforms with billing, roles, and scalable architecture • Fintech backends with secure payments, audit trails, and reliability-first design • Marketplaces and LMS platforms designed for high user concurrency • Cloud-native systems on AWS and Azure with CI/CD and deployment pipelines 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸: I operate 𝗹𝗶𝗸𝗲 𝗮 𝗽𝗿𝗼𝗱𝘂𝗰𝘁-𝗳𝗼𝗰𝘂𝘀𝗲𝗱 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿, not just a task executor. That means: • I design systems with scalability and failure modes in mind • I flag architectural risks early, before they become expensive problems • I prioritize clean structure, maintainability, and production stability • I take ownership from architecture → build → deployment 𝗧𝗲𝗰𝗵 𝘀𝘁𝗮𝗰𝗸: React, Next.js, Node.js, Python, .NET MongoDB, PostgreSQL AWS, Azure AI integrations (LLMs, automation systems, APIs) CI/CD, system architecture, cloud deployments 𝗗𝗲𝗹𝗶𝘃𝗲𝗿𝘆 𝗺𝗶𝗻𝗱𝘀𝗲𝘁: You won’t need to chase updates or manage micro-details. I communicate clearly, surface risks early, and ensure systems are built to production standards, not just “working code.” If you're building a serious product and need someone who can own architecture + execution end-to-end, I’m available for short-term builds or long-term engineering support.

I am a full-stack developer, specializing in mobile (iOS/Android), Wordpress and Social Media Marketing. After years of working with overseas Developers to help me build my very own startup, I noticed that besides being able to find Devs at a fraction of the cost, the majority of Devs found did very unprofessional work, they were not organized, did not test and had weak code/design skills. So where do bootstrapped startups go to develop their MVP's? I decided to be part of the solution. I now work with an amazing team of highly skilled developers/designers that understand the startup culture and specialize in fitting within a bootstrapped budget. I have experience working with startups; I’ve attended Founders Space, one of the top Incubators in the country based in San Francisco. Myself including our team have a wealth of knowledge when it comes to building a startup from an idea to a reality.
