Environment: Java, Spring MVC, JSP, JSTL, jQuery, YUI, AJAX, JavaScript, HTML, CSS, JMS, Tibco EMS, IBM MQ, Quartz Framework, Maven, AWS, Eclipse 3.1, Singleton, Factory, Proxy, Service Locator, Business Delegate Client: Zensar Technologies Ltd, India Mar 2019 Jan 2023 Role: Java Developer Project: Application Onboarding and Process Management Project Overview: Developed and managed an application that is utilized to onboard project data and manage the lifecycle of that data through a number of approval stages; the application would provide the ability to verify or move requirements and progress data entered by the business team through review and approval processes. Key Responsibilities: Involved in an Agile Software Development environment using Agile methods like XP and SCRUM and Test-Driven Development (TDD). I developed entity bean data schema and mapped it to the database tables, enabling, and optimizing the data for efficient processing. Developed Java Web Services for different phases and Used Struts2 framework to handle application requests using SOAP web services. I built stored procedures around typical and commonly used queries to speed up processing time and lessening wait time for users.

Associate Software Engineer Oct 2017 Feb 2019 Client: Octaware Technologies, India Project: Identify Types Project Overview: Developed a robust application designed to identify the native format of files, even when they are disguised with incorrect extensions. The application analyzed file headers to detect unique signatures, ensuring accurate identification of over 5,000 file types, thereby enhancing data integrity and processing efficiency. Key Responsibilities: I collaborated with my stakeholders including diverse business analysts and project managers to gather, elicit, and capture the requirements for the file analysis and the project produced the code for an implementation of a database management interface. I wrote the required algorithms, for reading and analysing file headers to detect byte sequences to accurately identify the native file format even if the extension is obscure or misrepresents the real format. I implemented the database to house the metadata of the identified file types, and also ensure that it is updated and stored in way that can be easily retrieved or access the information. I created a UI, as a Web interface to display the identified file formats and metadata of the file identified types enabling users to analyze files in an intuitive manner. Implemented SOA architecture with web services using SOAP, WSDL, UDDI and XML. I automated the process of transferring massive amount of private data from 1 client servers to another client using SCP (Secure Copy Protocol). I used IBM WebSphere as the application Server, whereas Apache Tomcat was used to develop the UI, and then as a testing phase before rolling out to production as an application server for the system. Prior to decommissioning the project, I used tutorial approach to collaborate to train the business analysts and project managers supporting the project. Collaborating and working in Agile practices: I collaborated with and contributed to cross functional teams. Business analysts, project managers and I worked to apply the Agile approach, to deliver required functionality in correspondence to project milestones, to meet the stakeholders' needs.
