PROJECTS

End-to-End Compression Detection February 2024 - Present Software Engineer

● Actively developing a C-based application aimed at detecting end-to-end network compression.

● Implementing a robust server-client topology designed to initiate a TCP connection, enabling the transmission of JSON payloads. This setup facilitates the server's reception and analysis of UDP packets during the probing phase.

● During the probing phase, the client dispatches a specified quantity of low-entropy UDP packets, followed by a brief pause, and then the transmission of high-entropy UDP packets.

● Utilizing the differential data from low and high-entropy packets, the server accurately assesses the presence of compression across the network and communicates its findings with the client. HTTP Server

Software Engineer December 2023

● Developed a custom HTTP server in C capable of hosting a variety of websites.

● Implemented server functionality using the poll function, enabling efficient, non-blocking handling of multiple simultaneous connections.

● Ensured adherence to TCP/IP protocols, guaranteeing reliable and standard network communication. SKILLS
