About

National Computer Olympics | TUBITAK Silver Medal | C++ Based Low Latency Trading | High-Frequency Trading (HFT) & Algorithmic Optimization | EEE & COMP Double MajorAs an Algorithm Developer with a double major in Electrical and Electronics Engineering (EEE) & Computer Science (COMP), I've honed my skills in high-frequency trading, successfully overseeing the entire HFT cycle—from reading market data, strategizing, to sending orders.My journey includes developing and optimizing C/C++ server programs for high-frequency trading on renowned exchanges like NASDAQ and Borsa Istanbul (BIST), leveraging ITCH, OUCH, FIX, and MoldUDP protocols. I take pride in having advanced knowledge of these protocols, which has aided me in optimizing trading applications to nanosecond-level latencies for superior performance. Used Onload and Mellanox Accelerating systems to bypass kernel.I've grown comfortable with Docker containers and server maintenance on Ubuntu/CentOS platforms, enhancing my ability to deliver consistent and reliable trading solutions. Working with relational databases, particularly PostgreSQL, has enabled me to manage complex datasets and transform them into actionable insights.I've had the opportunity to develop various strategic algorithms, including HFT, VWAP, and Arbitrage, among others, which has substantially expanded my understanding of different trading strategies and their real-world applications.Moreover, my experience with Amazon Web Service features such as App Config and Buckets has enabled me to leverage the power of cloud computing to facilitate efficient, scalable solutions in the financial trading industry. My story continues to evolve as I strive to innovate and drive success in the algorithmic trading realm.Also I have some experience with Xilinx Alveo FPGA Cards with Vitis.
