Hello there, Thank you for landing on my profile and for devoting your valuable time for my profile review. I have 10+ years of experience with web as well as mobile app development. Coding is my passion and I am living my passion every day, every line of code helping me to push the boundaries of my knowledge and experience. Also, I have tried my hands on the UI/UX and have substantial experience with the user-interface because the user-interface of any app is just like the reception which should be attractive and engaging at the same time. I strongly follow the steps of "Software Development Life Cycle (SDLC)" and everything will be developed under the fence of SDLC such as: ➥ System analysis and development plan ➥ Wire framing and app screen designs (UI/UX) ➥ Mobile app programming (Native and Cross-platform both) ➥ Backend + Database development ➥ Full app testing/QA ➥ Best release and feedback from client-side and other sources ➥ Final deployment on the app store ☛ I am proficient with the following technologies: ------------------------------------------------------------- ⇨ UI/UX: Photoshop, Sketch, and Illustrator ⇨ Cross-platform app development: React Native + JavaScript/TypeScript, Flutter ⇨ iOS App Development: Swift, Objective-c, Xcode, iOS SDK ⇨ Android app development: Java, Kotlin, Android Studio & Android Developer Tools and Android SDK ⇨ Backend development: LAMP (Linux, Apache, MySQL, PHP) or MEAN (MongoDB, ExpressJS, AngularJS, Node.JS, ), J2EE, Micro-services, Spring boot), Python, Django and Flask Python Frameworks I always understand the problems of the clients and execute them accordingly in real-time with the best way to solve it with high quality and strong mathematical and system control knowledge.

I fix overseas mistakes. Seriously I am appalled by people who think cheap = good. In the AI space I led the development team at CAMFIND (two million downloads) and TAPTAPSEE which uses AI for image recognition and now image captioning in real time. I also created Predictive Chat which mimics human like chat for the mortgage and lease renewal industry (sold to YTEL). Now I am working at SOUNDIMAGE.AI where I am using LLMs and generative AI models for flawless lipsynching, dubbing and other media tools. I am proficient in data science and data scraping. Former CTO of three start-ups. One was an app acquired by Amazon (SHOPPLER) and the other in the AI space (Cloudsight.ai). I also have excellent experience with video streaming. Most of the clients I have worked with thus far on this site had tried the cheap route abroad and I fixed them. I have worked at the several well known companies such as FANDUEL and TJMAXX. I was the lead app developer at the prestigious XPRIZE. I have created three apps that have had more than 1 million downloads. This means I can build robust apps that scale. I am here on Upwork because that's how I found one of the start-ups I have worked at that have had a great exit. I am a senior iOS/Android app developer with actual apps on the app store. I have excellent references and am local. I have several apps that have crossed the 100k+ download threshold and at least three that are 1Million+. I do not outsource overseas, and I am available to meet in the SoCal area as needed. I will work with you from inception of your app idea to launch on the app store or I can solve bug fixes as well. Hire me if you are looking for a serious person who will bring a CTO mentality of getting things done, someone with over 20+ years of problem-solving. Please do not let my hourly rate frighten you (it is there to eliminate non-serious offers). My skills are - Proficient with SwiftUI as well as React Native/Flutter to create hybrid or cross platform apps - iPhone,iPad, WatchKit App Development with SwiftUI, Objective C and Swift/XCode. - Android development with Android Studio and Kotlin -Streaming with MUX, Agora, Wowzaa - Bluetooth Low Energy, iBeacon - Integration of PayPal or Stripe SDK - Integration of Barcode scan/WalletPasses - Core Animation - Push Notification (APNS, GCM) - Storyboard, AutoLayout - iOS Keyboard Customization - Integrating in-app purchase - Integrating iAd and Admob - UI design of iOS and Android app - Video/Audio processing - Google Map Service, Apple Map Service, Geo Location - Camera/Photo manipulation stitching - Chatting by XMPP Framework - Callkit (Voip for apps) - Managing databases (MONGO, NoSQL, SQLite, Core-Data Model) - Working with Github, Bitbucket - Integration of Social Networking (Facebook, Twitter, Instagram, Youtube...) - Video/Audio Streaming, Video Editing, Decoding/Encoding -NodeJS -Mongo/PostGres - React. Vue, Next - Web Service, Ajax, XML, JSON - Back end admin panel -Piano integration -RevenueCat In the blockchain space I was the lead developer for VIBEHUT and DESOFY Thank you for your time and consideration.
