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.iPhone App Development

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.

Do you have a great idea for a web or mobile app but not sure where to start? I specialize in designing and developing apps from scratch! -Top 1% in app design & development by Upwork -Trusted by Harvard, Yamaha, UC Berkeley & Samsung -100+ 5-star reviews across different platforms (UpWork, Clutch, Yelp) Message me directly for a free consultation! About a decade ago I launched my oown application and startup called SchooLinks with no tech background... I hired the wrong freelancers, used the wrong tech stack, and made many other expensive mistakes along the way. It was a nightmare to say the least. I learnt that "cheap" can be expensive. While anyone can design or code, very few can create products that not only scale but also remain stable over time. This is critical when developing MVPs (Minimum Viable Products) and POCs (Proof of Concepts), where the right approach can make the difference between success and costly failure. After 2 years, I was able to finally launch SchooLinks. It has raised over $90 MM USD and became the industry leader of its category. I learnt to design, code and went back to school at UC Berkeley, where I became the VP of Technology for Entrepreneurial Association. During my time there, I helped dozens of startups launch their apps! This experience led me to want to help other fellow entrepreneurs and business owners to avoid the expensive mistakes I made. As a result, my clients have raised over $330 MM USD with web and mobile apps I helped them launch. You can count on me being upfront when I don’t think we are a good fit and point you in the right direction. Schedule your consultation today! My preferred tech stack includes: Figma, Flutter, NodeJS, Angular, AWS & MongoDB. I also have solid experience integrating API’s, including Stripe, ChatGTP and Twilio.iPhone App Development

Building efficient MVPs for early-stage startups. As a full-stack developer with over seven years of experience, I specialize in creating scalable apps for mobile and web platforms. I have helped non-technical founders build apps for their startups that have been accepted into top startup accelerators like YCombinator and TechStars. Three main reasons why building an MVP is a great idea: ⏱️ It Is Faster: Creating an AI-powered MVP takes less than two months, allowing you to quickly validate your concept and identify your product market fit. 💵 It Is More Cost-Effective: Compared to the cost of developing a full-scale app, an MVP can save you up to 200%. 💰It Is Profitable: Developing an MVP can help you secure a startup accelerator acceptance or raise a pre-seed/seed investment round. In today's market, investors typically require startups to have a validated product and traction rather than just an idea. My full-cycle MVP development service includes UX/UI design, full-stack development, QA testing, and post-launch support. Please feel free to contact me for more information.iPhone App Development
