    “If you give a man a fish, he will be hungry tomorrow. If you teach a man to fish, he will be richer forever.” Before talking about qualifications and professional abilities, I would like to mention my personalities and traits myself. Taking software development and engineering as a profession not only fills my pocket but also my heart because it has been my passion since my early teenage years. I believe that people should do things in which they are good at or in which their heart lays. That’s why I chose freelance software development as my career because I believe I’m good at this and as I am always honest and I am never afraid of doing hard work. My favorite technologies are Dart and JavaScript because they run fast, and they can be used for both the client-side and the server-side. As a dedicated software engineer, it’s amazing to use flexible languages on the end, and it has thousands of great libraries and frameworks. I am especially specialized in Flutter and React and have developed and deployed 100+ mobile iOS and Android applications and websites with those stacks until now. **The reason why I choose React.js in the front-end library is its extra simplicity and flexibility and also popularity.** While ReactJS is a great framework that every developer wants to use regularly, other great frameworks are also effective. Your full-stack web app will be unique in looking, fast, and user-friendly. I can also develop and design a single-page application using React.js with the power of Redux. I can guarantee that you will be 100% satisfied with the outcome. [ CORE SKILLS ] - Dart | Flutter | DartX | Kotlin | Java | Swift | FlutterFlow - HTML | HTML5 | CSS | SCSS | LESS | Bootstrap | Tailwind | Material UI - JavaScript | jQuery | TypeScript - Android Studio | MS Visual Studio Code | XCode - React.js | Next.js | Gatsby.js | Redux | Mobx - Firebase | MongoDB | MySQL | PostgreSQL | Drift SQL | Google Play Store | App Store [ SPECIAL SKILLS ] - iOS and Android Development - Hybrid and Progress Web App (PWA) Development - Cross-Platform Mobile app development - Web Scraping [ SERVICES ] - Responsible communication (any time). - Flexible Time Zone - DevOps | Git | Heroku | Docker - Camera | GPS | Social Network API Integration - UI/UX design to Flutter - Stripe | Skill | PayPal | Flutterwave | PayStack Payment Services - Deliver Daily or Weekly results. - Full Time (24/7) Commitment. - Provide professional code like the Unit test in RESTful API endpoint. Besides, my mobile applications and websites are SEO friendly because they did not fail to satisfy the users. Again, I keep myself up to date with new technologies and their uses, new tools and computer languages so that I can give my level best to my clients. I believe in hardship and hiring me would not fail your decision. Thank you.

    As a Rhodes Scholar with a doctorate in theoretical physics from Oxford University, I am well versed in both the scientific and creative arts. Whether your project requires an analysis of data, a design of apparatus, or a literal presentation of information, you can put me to work with confidence that the final product will exceed your expectations. My publications appear regularly in reputable journals and cover a wide range of topics. My consultancy Alphawave Research can help you address many of your technical needs, whether academic, commercial, or industrial, on a tight schedule and with spectacular results. What I practice is best described as inductive reasoning, otherwise known as inferential statistics. Inferential statistics encompasses both descriptive statistics (e.g. hypothesis testing) and predictive statistics (e.g. forecasting). A good description of what I do is found in D. S. Sivia's Data Analysis: A Bayesian Tutorial. That book is a quick read and easily skimmed, so if you can find it in your library or bookstore, please have a look at it. If you like what's going on there, you'll like what I can do for you.
