I have been making Hybrid apps since last 5 years, have been trained by Google Inc. for making PWS and using my diplomatic skills with Apple everyday to make sure all apps get approved. As the world around us keeps changing rapidly, majority of such changes are happening because of the advancement in technology. While it sounds all impressive just discussing new stacks and scripting languages proving it via working solution is always a tough task. If you find framework or stack that looks promising enough and holds some promise for better future, I can pick up your vision and make it all shine. While giving a shot with new frameworks I also work with things those are very well established by now. For me those things are Angular, IONIC, Node, ReactJS, Vue.js and Javascript in general. I have been keeping a track of how ReactJS and React Native Is evolving in parallel track with IONIC 4 and also keeping hands on Vue.JS. Away from Javascript I am currently spending time on TensorFlow for Machine learning and coming up with several models of Machine Learning. For clients who knows their business inside out but do need help when it comes to the technology I become their guy. This approach has helped several people from small businesses to bigger corporation to bring value to their own work and profiles as well has helped them to succeed in their own enterprise goals. I have a degree in Computer Science and my git reflects all the hardwork I have done so far in these 5 years. Lets make it together.

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.
