Kuldeep K.

I’m a Mobile App Developer with 10+ years of experience building iOS and Android applications, with a strong focus on 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞, 𝐅𝐥𝐮𝐭𝐭𝐞𝐫, 𝐖𝐞𝐛𝐑𝐓𝐂, 𝐥𝐢𝐯𝐞 𝐯𝐢𝐝𝐞𝐨, 𝐚𝐧𝐝 𝐬𝐭𝐫𝐞𝐚𝐦𝐢𝐧𝐠 𝐩𝐥𝐚𝐭𝐟𝐨𝐫𝐦𝐬 Over the years, I’ve worked on everything from startup MVPs and business applications to real-time communication, video calling, streaming, surveillance, and AI-powered products. If you have an idea, an existing application that needs improvement, or a product that has become difficult to maintain, I can help you take it from requirements to a production-ready release. 𝐖𝐡𝐚𝐭 𝐈 𝐰𝐨𝐫𝐤 𝐨𝐧 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 React Native and Flutter applications for iOS and Android, including custom UI, API integrations, Firebase, native functionality, push notifications, payments, and third-party SDK integrations. 𝐋𝐢𝐯𝐞 𝐕𝐢𝐝𝐞𝐨 & 𝐒𝐭𝐫𝐞𝐚𝐦𝐢𝐧𝐠 Live streaming applications, video platforms, broadcasting solutions, webinars, video feeds, recording, playback, multi-camera streaming, and low-latency video experiences. 𝐖𝐞𝐛𝐑𝐓𝐂 & 𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧 Video and audio calling, one-to-one and group communication, real-time rooms, screen sharing, messaging, and other WebRTC-based applications. I have experience working with technologies such as WebRTC, LiveKit, Agora, Twilio, SIP, RTSP, RTMP, HLS, FFmpeg, GStreamer, Janus, MediaSoup, Kurento, and Jitsi. 𝐕𝐢𝐝𝐞𝐨 𝐒𝐮𝐫𝐯𝐞𝐢𝐥𝐥𝐚𝐧𝐜𝐞 & 𝐂𝐚𝐦𝐞𝐫𝐚 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 IP camera applications, live camera feeds, mobile-as-camera solutions, multi-camera monitoring, remote viewing, recording, and smart video functionality. 𝐀𝐈 & 𝐂𝐨𝐦𝐩𝐮𝐭𝐞𝐫 𝐕𝐢𝐬𝐢𝐨𝐧 AI-powered mobile applications involving object detection, facial analysis, speech-to-text, AI assistants, captions, voice features, and real-time video analysis. Depending on the project, I work with OpenAI, Claude, Whisper, OpenCV, YOLO, TensorFlow, PyTorch, Core ML, and other AI/ML services. 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐜𝐚𝐧 𝐡𝐞𝐥𝐩 I’m comfortable joining a project at different stages: • Building an application from scratch • Turning Figma designs into a working mobile product • Developing an MVP for a startup • Taking over an existing React Native or Flutter application • Adding WebRTC or live streaming functionality • Integrating APIs, payment gateways, Firebase, and third-party services • Fixing bugs and performance issues • Modernizing an older mobile application • Reviewing an existing architecture and suggesting improvements • Preparing an application for App Store and Google Play release 𝐌𝐲 𝐮𝐬𝐮𝐚𝐥 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐬𝐭𝐚𝐜𝐤 𝐌𝐨𝐛𝐢𝐥𝐞: React Native, Flutter, Swift, Kotlin, iOS, Android 𝐕𝐢𝐝𝐞𝐨: WebRTC, LiveKit, Agora, Twilio, FFmpeg, GStreamer, HLS, RTMP, RTSP 𝐁𝐚𝐜𝐤𝐞𝐧𝐝: Node.js, NestJS, Python, REST APIs, GraphQL, Firebase 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞: PostgreSQL, MySQL, MongoDB, Redis 𝐂𝐥𝐨𝐮𝐝: AWS, Docker, CI/CD 𝐀𝐈/𝐌𝐋:OpenAI, Claude, Whisper, OpenCV, YOLO, TensorFlow, PyTorch, Core ML 𝐀 𝐥𝐢𝐭𝐭𝐥𝐞 𝐚𝐛𝐨𝐮𝐭 𝐡𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤 I prefer to understand the product before jumping straight into development. First, I look at the requirements, existing application, designs, APIs, and technical challenges. Then I help define the development approach, break the work into practical milestones, and keep communication clear throughout the project. For me, a successful project isn't just about getting the app to work. It should be stable, maintainable, responsive, and ready to handle real users.
