    As a software developer for the last 13+ years, I have helped many clients develop software applications based on desktop, web-based (front-end and back-end APIs), and mobile (front-end and backend APIs) platforms. I developed most of the applications in Java-based technologies and Spring Framework, Microservices, Struts2, JavaFX, and front end as HTML5/CSS3/JavaScript/ES6/JQuery and ReactJS I have also completed jobs related to the configuration and customization of ERP solutions like Ofbiz and Moqui In mobile application development, I am more comfortable in developing mobile applications using React Native. I developed applications in various domains by using the most popular databases, including Oracle, MySql, SQL Server, Postgres, etc. I am good at developing Oracle PL/SQL code for enterprise applications. Project management and code version control tools are essential for the smooth progress of the project, and I am comfortable in Git, JIRA, Redmine, Bugzilla, Basecamp, and Trello, etc. During this journey from developer to architect, I have enjoyed every moment of it and learned how to develop scalable and robust applications and recently have invested in learning Test Automation, Kubernetes, Mockito, and integrations containing Zapier, Quickbooks, and Zoho, etc I believe a detailed discussion at the project's initial stage but quick and regular communication during project development is key to success. Availability: 30-35 hours/week. Excellent communication skills. Thanks Harkomal Singh
