Worked on integration with other platforms (Azure DevOps, JIRA) from ServiceNow. Developed Store Apps and Plugins following best practices as suggested by the ServiceNow platform. 
I have experience in working with Business Rules, Script Includes, Client Script,  ACL, Flow Designer, REST API Integration, Extension, and other components of the ServiceNow platform. I also worked on the Performance Analytics component and developed multiple dashboards. 

While developing web applications,I have got tasks like load testing, video compression, audio compression. One could use some software and do this, but this process also includes you to manually provide the files. I have written a shell script in which you just have to put the files in some specific folder and all the things will be taken care of.

Used Grinder as a Load Tetser. Written load testing scripts in Jython for all separate transaction in the application. Helps in finding performance bottleneck and thus improves throughput and response time. 
While load testing we have to wait for some time for the process to complete. I have automated the whole process of load testing using shell script. The script used to run at the night and in the morning I have all the performance statistics from the database, application, file, and reverse proxy servers.

I have been working with Java for 6 years. I have used Spring, Hibernate, JPA framework in Java for making server sie applications. 

 I regularly handle PostgreSQL and MySQL administration tasks and writing MySQL and PostgreSQL queries. Strong understanding of normalization and database relationships.

Used mentioned technologies to build a passwordless authentication system. People with low literacy cannot remember the password, so built a system where they don't have to remember the password. Used symmetric encryption-decryption and token-based authentication system.
