    I am a very responsible, skilled and result-oriented software engineer. - Area of Expertise * Python & Django * C, C++ * JS (AngularJS, JQuery, Ajax) * Hybrid Mobile Application(Android, iOS App(iPhone, iPad) , Cordova, Ionic) * Database (MySQL PostgreSQL) * AWS services Cross-platform apps have been my focus for the past few years. Building a cross-platform app is the best way for startups and lean companies to get their app running. The app can get built faster, requires only a single developer (or small team), and is exactly as powerful as native apps (except for games). I've been building apps exclusively through the Cordova platform for years, as can be seen in my portfolio overview. I have even more experience in building scalable backend services (Django, MySQL) to power those apps in a way that they can quickly grow without having to re-do the work once the app reaches a significant user mass. I have experience in deploying Cordova apps to the app store and play store, deploying Django applications to servers, Building front-end apps using AngularJS and ReactJS. With those skills, I'm able to offer an all-inclusive (App, backend platforms, admin tools) package to get your idea up and running while you can focus on marketing and new features! --- More Flexible Every field of technology and trends --- Thanks a million.

 Apache Spark™ 2.X - Tableau Desktop Qualified Associate I'm looking for one-time and ongoing projects. I especially enjoy working with large datasets in the finance, healthcare, ad tech, and business operations industries. I possess a combination of analytic, machine learning, data mining, statistical skills, and experience with algorithms and software development/authoring code. Perhaps the most important skill I possess is the ability to explain the significance of data in a way that others can easily understand. Types of work I do: - Consulting: How to solve a problem without actually solving it. - Doing: Solving your problem based on your existing understanding of how to solve it. - Concept: Exploring how to get the result you are interested in. - Research: Finding out what is possible, given a limited scope (time, money) and your resources. - Validation: Guiding your existing or new team is going to solve your problem. My development environment: I generally use a dual computer-quad-monitor setup to access my various virtualized environments over my office fiber connection. This allows me to use any os needed (mac/windows */*nix) and also to rent any AWS hardware needed for faster project execution time and to simulate clients' production environments as needed. I also have all tools installed in the environments which make the most sense. I'm authorized to work in the USA. I can provide signed nondisclosure, noncompete and invention assignment agreements above and beyond the Upwork terms if needed.
