About

As an Senior Software Engineer at Upstox, I contribute to the development of scalable and efficient solutions for high-concurrency, low-latency distributed systems. My work has included projects such as creating tick-by-tick (TBT) charts for real-time market accuracy and automating complex financial processes, including Margin Trade Facility (MTF) conversions and cross-trade optimization. I have also developed backend systems for mutual funds and contributed to a trading guide nudge engine for real-time risk analysis. I hold a Bachelor of Engineering in Computer Science from R. V. College of Engineering and am currently pursuing a Master of Science in Computer Science at Woolf (Scaler Neovarsity). My technical expertise includes large-scale systems, version control, and Gradle, which I leverage to deliver impactful and data-driven engineering solutions in the fintech domain. Driven by a commitment to solving complex problems, I aim to design systems that enhance operational efficiency and user experiences.
