Project Name - Divine Drive Backend DevelopmentDeveloped an end-to-end solution to replace the existing backend solution with a modern backend server written in NestJS using TypeScript. Additionally, I have developed a CRM solution using Next.js, which is styled using TailwindCSS.

Project Name - Parasdham Girnar AccomodationDeveloped a comprehensive solution, starting from the ground up, which is a mobile-first hotel booking web application. The solution includes a CRM system and integration with payment gateways and SMS gateways, which together deliver a more seamless user experience.

I have developed backend APIs that connect with external gRPC servers using NodeJS, ExpressJS and MongoDB. I have also created a software licensing solution that verifies product keys using various cryptographic solutions.

Wrote clean, efficient, modular and optimized C code to emulate functions of PHY, MAC, RLC layers of LTE protocol stack as per 3GPP specifications. Some of the features for which I was directly involved in realizing include: -• Preforming encoding on Outgoing Data and Decoding on Incoming data as per 3GPP specified coding algorithms• Creating control data or metadata for outgoing data which helps the mobile phones in receiving data and identifying the data blocks relevant to the mobile phones• Converting the outgoing data bits to IQ Samples (complex value represent digit signals) using modulation schemes provided in the specification• Applying Discrete Fourier Transform on the Frequency Domain IQ Samples to get Time Domain IQ Samples which are then sent to Radio Unit(RU) to be converted to Analog Signals and transmitted via antennasNotable accomplishment in the job was developing PRACH receiver using C which was solely developed by myself, this gave me quite a lot of understanding of Fourier Transforms and working knowledge of Digital Signal Processing.Also worked on some smaller projects during my job include :-• Using ReactJS to make working webpages for clients• Making basic docker containers which will host the final RAN when it is ready • Connecting Docker container to a FPGA using Network Function Virtualization, granting me understanding of pnf and vnfs

Developed software applications for F1-CU protocol, adhering to 3GPP specifications, which included S1AP, RRC, and PDCP.Implemented and optimized F1-CU protocol functionalities for smooth communication between different network elements.Collaborated with cross-functional teams to troubleshoot and resolve technical issues in the software applications.Conducted thorough testing and debugging of the software applications to ensure smooth functioning and high performance.Actively participated in code reviews, providing valuable feedback and suggestions for improvement.

Developed a highly impactful web application using Angular 2.0 and NodeJS, resulting in a significant contribution of 50% of inbound traffic for an e-commerce startup.Implemented Nginx and PM2 to effectively deploy the application on AWS, ensuring smooth and efficient performance.
