Tools: REACT, javaScript, node.js, C++, SharedMemory, Semaphores

• Full stack development of Interactive space debris UI showing thousands of space debris moving in real time. Develop new javaScript files to load JSON file of all space objects and render in new HTML pages.
• Real time implementation of Regression algorithm in multi thread RTOS(C++) for radar tracking data. This involves Inter process communication and algorithms.

Tools: Python script, C++(OOPS), Azure, ML-Tensor

• Python interface to space-track.com website. Script to sign-in and download requisite data from website and move to remote server.
• Developed EKF-MHT-JPDA tracking algorithm for Multi Object Tracking Radar. This algorithm is first validated in python using scipy and numpy libraries, later realized in RTOS (C++) .
• Detailed analysis of feasibility of Particle filter and Unscented Kalman Filter using ML based data processing on Azure. Algos with Tensor scripts are run over Azure cloud and study report on same is published.

Tools: Qt-C++ (GUI), SQL, SQL DB, Linux, Unix, FTP, TCP, UDP, RS232.

• As engineer developed various Radar graphical user interface using Qt-C++ IDE. GUI should read TCP/UDP data from radar and update over desktop GUI. A multi threaded C++(OOPS) based GUI for radar control and data display is realized.
• Write custom SQL scripts to store large sets of radar classification data to SQL DB. Enable custom Web UI screens to radar persons based on new requirements.
• Write custom scripts for automation of Unix OS for day to day operations of radar.
• Prepared SRS and SDD documents for GUI realized. Submitted to ISPD (IEEE-1520 guidelines) review committee of ISRO.

• Develop code as per low level design document provided by Business Analysts.
• Write custom SQL queries and enable user screens for internal team members.
• Prepare unit test plan document for components to be migrated so that results can be compared.
