Full-Stack Web Development & API Integration
Great mobile applications require solid infrastructure underneath. I build complete full-stack solutions from backend REST APIs to beautiful user interfaces, ensuring every layer works together seamlessly. My full-stack development expertise includes database design (PostgreSQL, MongoDB, Firebase), RESTful API development, GraphQL implementations, real-time WebSocket communication, authentication systems (OAuth, JWT), and responsive front-end interfaces.
This comprehensive technical knowledge allows me to make informed architecture decisions, optimize performance across the entire technology stack, implement security best practices at every level, and build solutions that scale as your user base grows. Whether you need a simple API for a mobile app or a complex real-time system with bidirectional communication, I focus on building maintainable, well-documented solutions.
Technical Skills & Expertise
Over years of building production applications, I’ve developed deep expertise across the full mobile and IoT development stack. From writing performant React Native code to implementing complex backend integrations, my technical skills span languages, frameworks, and specialized domains. Here’s a detailed look at the technologies and practices that power the solutions I build.
Mobile Development Technologies
My mobile development expertise centers on React Native development, which I use to build cross-platform applications for iOS, Android, Apple TV (tvOS), and Amazon Fire TV. React Native’s component-based architecture enables faster development cycles and easier maintenance across platforms, but I don’t sacrifice platform-specific features when they’re needed for the best user experience.
I’m equally proficient with native mobile development using Swift for iOS and Kotlin for Android when projects require specialized functionality, maximum performance, or deep system integration. This hybrid approach means you get the efficiency of cross-platform development with the power of native capabilities when needed.
Beyond coding, I understand the complete mobile ecosystem including App Store Optimization (ASO) for improved discoverability, in-app purchase implementation and subscription management, push notification services (Firebase Cloud Messaging, Apple Push Notifications), mobile analytics and crash reporting (Firebase, Crashlytics), deep linking and universal links, and continuous integration/continuous deployment (CI/CD) for mobile apps.
Backend Development & IoT Integration
On the backend, Python development is my primary focus, particularly for building Home Assistant custom integrations and RESTful APIs. Python’s extensive library ecosystem, readability, and strong community support make it ideal for rapid development and long-term maintenance.
My IoT and smart home integration expertise includes MQTT protocol implementation for lightweight device communication, Zigbee device integration through coordinators like Zigbee2MQTT, Z-Wave network setup and device pairing, REST API integration for cloud services and devices, WebSocket connections for real-time data streaming, and local network device discovery protocols (mDNS, SSDP, UPnP).
This protocol knowledge enables integration of virtually any smart device—from Philips Hue lights to custom sensors—into comprehensive home automation systems that prioritize local control and user privacy.
Software Development Best Practices
Quality software requires disciplined practices. I follow Agile development methodologies with two-week sprints, daily standups, sprint planning and retrospectives, and continuous stakeholder communication. My projects implement CI/CD pipelines using GitHub Actions, GitLab CI, and Fastlane for automated testing, code quality checks, and deployment.
I practice test-driven development (TDD) where appropriate, writing unit tests with Jest and React Testing Library, integration tests for API endpoints, end-to-end tests with Detox for mobile apps, and automated UI testing. Version control with Git is fundamental, using feature branch workflows, semantic commit messages, code review processes, and Git hooks for quality enforcement.
Specialized Technical Expertise
Some of my most distinctive work involves specialized domains. Color science and display calibration requires understanding color spaces (sRGB, DCI-P3, Rec.2020), gamma curves and transfer functions, HDR metadata (HDR10, Dolby Vision), and colorimeter/spectrophotometer integration. This expertise powers applications like LightSpace Connect for professional display calibration.
Smart TV application development for tvOS and Fire TV demands adapting to D-pad navigation instead of touch, optimizing for 10-foot viewing distances, implementing focus management systems, and supporting remote control inputs. Animation and UI/UX design involves building custom animation engines, optimizing for 60fps performance, implementing gesture recognizers, and creating intuitive navigation patterns that feel natural across platforms.
