    I have 11 years of working experience in video streaming, web development, and mobile app development. I have developed several custom modules for video transcoding, live recording, chat, video conference, IP camera restream, IPTV channel restream, and several others. I like to give a demo or POC first and then start a real project; this makes the vision more clear to both parties (buyer and service provider). I completed my postgraduate degree in 2007, and after that, I started my professional career in Java Struts/Spring and Hibernate. After that, I started the core apps of Android in 2010 and then started XMPP-based chat apps for iOS. Video Streaming: I have been working with WOWZA, Red5, and FMS since 2009. I started using NODE JS, React JS, and Socket JS HTML5 with WebRTC because this technology is growing rapidly and modern browsers are also ready to support it. I have good experience with Fabric.JS for HTML5 canvas-based video editing and drawing tools. I believe success only requires hard work and an honest attempt.

    Hi And welcome to my profile, I have over 4 years of experience with Android development and over 2 years of experience with Flutter development I was born to be a computer software engineer and then in the age of 14 I jumped into the programming. later I completed my Software Engineering degree and became an Android Developer. I chose Android because I like working on operation systems and open for new challenges. I have developed native applications similar to Uber and WhatsApp why should you hire me? Here are the advantages to hire me: ● Responsible for my role in work. ● Available 30~50 hrs/week, on any time zone ● Top quality with top speed ● Accurate and keen eyes for pixel perfect UI/UX design, as well as bug free coding skill ● Good communication with professional English ● For the biggest advantage, I'm younger yet and have a big potentiality to become familiar with any new aspects or fields. My passion is actually to explore new fields and to investigate new technology. I have been already an expert in Android, but have much more abilities. I'm open to any kind of discussion on your project. Please feel free to touch me. Hope to work together for an amazing product. less

At A Glance: Core Java

Developing and programming software is the backbone of many modern businesses and industries. Programs and applications can be created to fill many different roles, including games, e-commerce, and interactive web content. These applications can be used internally for tracking and managing other digital resources, or developed as standalone software to distribute to customers and consumers. One important feature of any program is that it is written and developed in a programming language that allows it to be easily ported and executed on other computer systems. Core Java, commonly known as Java Standard Edition (SE), is one such programming language that gives you the portability and flexibility in your developed software that you need for your business and project. Taking advantage of an experienced Java developer or programmer is the most effective way to leverage this powerful language.

Java developers and programmers available on Upwork generally possess a deep knowledge and skill set. Backgrounds include building, writing, and developing programs from the ground up for a wide variety of uses. Java developers and programmers also have experience working with existing applications by adding additional functions or features. Core Java developers and programmers are highly computer-literate professionals with advanced mathematical skills and frequent experience working with other computer programming languages and development frameworks. The portable nature of applications written in Core Java lead to programmers’ and developers’ comfort with many different systems, which fills dynamic roles within a business or project.
