Full Stack Web and Mobile Project Manager

As a senior web and mobile app developer of the impressive work being done by my own efforts, I was responsible for enhancement, development and maintenance of current project CMx. With over 10 years of achieving profitability and smart skills, I satisfied the manager of this company. After promoted to the project manager, I struggled to make a vivid improvement in the project. The main affair was to build the secure, fast and user-friendly APIs in the big Spring Java/JSP project. And also, developing the mobile and desktop apps with Flutter. Converting the Front-end to React based smart UI was also one of my great achievements there. With our honorable efforts, over thousands of clients are loving the CMx, and it brings me the valuable delight and memorizable thing. The main project was the contract experience. Contract Experience provides simple, reliable, legally compliant Centralized Contract Management Repository that is secure & customizable for automating and optimizing your contract process from request to electronic signature to approvals connecting users from multiple groups, departments and geographic locations. Like most other large scale company management platforms, It uses Java. Implementing the UI on web was realized by react.js and on mobile side by flutter. The challenge was to design the oauth2 server with MDN. I confirmed my skill in frontend and backend development and had the confidence in my stack.

Experience with AWS (EC2, S3, RDS) and other cloud-based services made me more comfortable in development and engagement in the team. I wrote effective, scalable code to develop back-end components to improve responsiveness and overall performance. My focuses were integrating user-facing elements into applications, test and debug programs, improve functionality of existing systems, implementing security and data protection solutions, assessing and prioritize feature requests and coordinating with internal teams to understand user requirements and provide technical solutions. My activities also involved the Laravel development in a great team. I could acquire the knowledge of developing the web based applications using LAMP, WAMP, PHP etc. That was the important time for consolidating the knowledge of technologies including XML, web service, jQuery, PHP5, MySQL, Python, OOPS, Design Patterns, HTML5, CSS etc. Also, I could strongly understand the API driven design with versioning, designing and developing the interactive user interfaces, usability, web and client / server applications using HTML5, CSS3, jQuery. The most active part that even I cannot forget until now is the time when I worked to get the experience on implementing and understanding the AJAX features. The conception of Laravel had been built that time, and it was really my great opportunity to get experienced in PHP web applications.
