I'm a solo Dev. I have more than 9 years of experience in Mobile development and web development. I have been working with the cross-platform framework React Native for 6 years and am still working. This is my main stack right now. I use TypeScript and JavaScript to make React Native apps. I tried the Flutter framework back in 2020, and I like it. I now use Flutter to develop cross-platform applications, and I like it more and more. I feel that I will soon switch completely to Flutter only! Flutter is less of a headache :) Back in 2012, I started my career as a front-end web developer with JavaScript. Since 2015, I started developing for Android applications, and after a year of work, I bought myself the first MacBook to make native applications for iOS. Do you remember Objective-C? I do)) I'm interested in long-term customer relationships, so I am ready to participate in your project from idea to production and provide high-level support after delivering the main work. - I have been using FlutterFlow as well since 2023, and I like it. So I can help you with FlutterFlow if you need it - I like web3 and already have experiance with cryptocurrency token launch and blockchain development Below is my humble list of tools I have experience with or enjoy working with: - React Native - TypeScript - Flutter - Dart - Swift - Kotlin - FlutterFlow - I can make a Native Swift/Kotlin component for React Native or Flutter - GitHub Actions I have used for CI/CD This is an easy way to automate tests and app delivery - Fastlane for CI/CD is the easiest way to automate tests and app delivery - Node.js - React.js - Redux - GraphQL - FastLane/circleci - RevenueCat - Firebase Cloud Firestore - Firebase Realtime Database - Firebase Remote Config - Firebase Cloud Functions - Firebase Authentication - FirebaseCloud Messaging - Firebase Hosting - Firebase Cloud Storage - Firebase Machine Learning - Firebase Dynamic Links I usually write autotests for code. I use these tools: - Jest - Mocha - Jasmine +++++Web3 development:++++++ - blockchain development - Crypto Wallet integrations - MetaMask integration - Alphawallet integration - Experience with coding competitions, e.g. ACM ICPC or Topcoder - cryptocurrency token launch - Casino Game development (including spinner, coinflip, lottery, splash, etc.) - I have already had experience in ChatGPT integration and other AI integrations. Other: - branch.io - ChatGpt integration - OpenAI - Sentry - Tokenscript - Heroku - AWS - DigitalOcean - DApps - retool - internal software development - DeFi projects - LayerZero Im not a Full-stack dev, but I have some experience with Python, Node.js and the Django framework!!!

Game and application veteran team well-versed in cross-platform SDKs and native application development for iOS and Android. Also have tons of relevant experience working with Sony, Microsoft and Nintendo platforms. Deep development experience with Unity, Unreal, React Native, Corona/Solar2D, SwfitUI and Java.

100% biological, natural brain for rent! A natural deep neural network trained for 15 years on software development tasks of varying complexity. Trained on large datasets of C/C++, C#, and other programming languages source code and technical documentation. The medical device industry, X-ray imaging, game development, WPF .NET desktop software development, and Unity game engine datasets were a significant part of the training program. Capable of stable performance at System 2 level, rarely dropping to Level 1, only in stressful situations. Produces near-perfect source code and final software solutions. Very well nurtured: good sleep, nutrition based mainly on a high-protein diet. No alcohol consumption during all years of training and subsequent inference (practical application) to keep the bloodstream and cells intact. Attached to a healthy and well-maintained human body. Can also work well in symbiosis with LLM if you prefer tasks done faster with a little help from AI.
