Hey there!Namaste!Konnichiwa!

I'm a systems engineer at Quadeye Securities building low-latency trading systems, making them faster and accurate by whatever means necessary. Computer Science graduate from IIT Kanpur, passionate about computer systems and excited by elegant patterns, sophistication, and efficiency.

Now ⚡

At Quadeye I chase latency and squeeze accuracy and performance out of trading systems for both production and simulations modules. Some may call this role as performance or low-latency engineer at an HFT firm. By design, this space rewards bringing ideas to the table and executing on them, so my days are spent hunting the best or next-best solution to (rather involved) problems. It keeps me on edge, and honestly, I wouldn't have it any other way.

Off the clock I'm tinkering with my kernel, my compiler, or whatever I just read in a blog, white paper, etc. So far that has resulted in tweaks to GCC, a home network, custom drivers, and a versatile 4K-SLoC bash source file, among other things. If you've got something cool I should check out, or want to explore together, reach out.

Where would the courage and greatness be if success was certain and there was no risk.

Interests 🧠

I'm in awe of how system components couple so elegantly, and I love making applications run faster without wasting compute. Apart from the goal of creating an impact, my driving force is solving problems that lack an obvious solution.

• Heterogeneous computing
• Domain-specific accelerators
• Large-scale systems
• Computer architecture
• Linux kernel
• Compilers
• Programming languages

I try to keep up with MLArchSys, ASPLOS, EuroSys, OSDI, HPCA, ISCA, PLDI, and MICRO, and with CppCon, RustConf, and GopherCon for the latest in language design.

Beyond code 🎶

In a previous life I studied Computer Science at IIT Kanpur, where I researched with Dr. Debadatta Mishra and Dr. Swarnendu Biswas on kernels and Unified Memory. I also spend time working on impact and was awarded the Best Socially Relevant Project at Convocation 2024. I was also part of several student bodies, leading a few and representing student interests in policy decisions. Despite being at an HFT, I sometimes believe my undergrad was much more time-intensive.

Away from the terminal I listen to music, play badminton, travel for new experiences and cuisines, and watch anime. Always up for a good conversation; feel free to hit me up.
