Avinash K.
Mobile App Developer | iOS & Android | Full-Stack App Development
Full-stack software developer with 18+ years of experience building reliable, production-ready web and mobile applications. I specialize in PHP, JavaScript, backend architecture, API integrations, and mobile app development, with hands-on experience taking products from idea to launch. In my current role as a Senior Developer, I build and maintain production applications while independently developing and shipping mobile products under Anpixels LLC. My published apps include USCIS Case Tracker, Birdly AI an AI-powered bird identification app using on-device machine learning and Kids Games 3-5 No WiFi, an offline early-childhood education app. These products are live on the App Store. I’m comfortable owning the entire product development lifecycle, including: Frontend & UI/UX: Building intuitive, responsive, and user-friendly interfaces. Backend Development: Designing scalable application architecture and business logic. API Integrations: Connecting third-party services and building reliable data flows. Mobile Development: Developing, testing, and shipping production iOS applications. AI & Machine Learning: Integrating practical AI capabilities, including on-device machine learning. Deployment & App Store Submission: Managing production releases, troubleshooting, and maintaining live applications. What sets me apart is my ability to combine deep development experience with real-world product ownership. I understand the technical details, but I also focus on usability, reliability, and delivering software that people can actually use. Whether you need a mobile app built from scratch, an existing application improved, a backend developed, or a product taken from concept to production, I can help turn your requirements into a working, polished solution.
