I have been developed many parts of software for over 11 years. Major areas of my expertise include: ✅ Mobile App development (iPhone, Android, Hybrid, Unity3D, Cocos, ...) ✅ Web development (PHP, Python, NodeJS, AngularJS, Wordpress, Shopify, Laravel, AWS, Heroku) ✅ Desktop Application (C/C++, C#, Java, QT, ...) ✅ Database (Firebase, MySQL, MS SQL, Oracle, SQLite, ...) I always aim to maintain a long-term relationship with my clients. Whether you've lost your original developer, need additional resources, or want a brand new app, I can step in and take over wherever you need. For now, I am a manager of a team that has 5 full stack mobile&web developers. We guarantee clients high-quality code and fast speed. We also provide free maintenance 6 months after finishing the project. Please kindly touch us here and get success from there! Thank you for reading.

Digital image processing is playing an increasingly important part in imaging based flame monitoring systems. A crucial step in flame image processing is to detect the flame edge, a dividing boundary between the area where there is thermo- chemical reaction and those without.
