Bio
I am currently pursuing my Master’s in Computer Science at Georgia Tech, specializing in Computing Systems with a 4.0/4.0 GPA. I completed my bachelor’s degree in Computer Science at the Indian Institute of Technology Bhubaneswar in 2022, ranking 1st among all undergraduates.
I worked as a Senior Member Technical at The D. E. Shaw Group from 2022-2024, where I led trading middleware optimization and achieved significant performance improvements. At D. E. Shaw, I achieved a 40% trading middleware performance boost and 93% reduction in Kafka application startup time. I also led UI design and mentored summer interns.
My work focuses on building high-performance, fault-tolerant systems for quantitative trading, with expertise in performance engineering, multithreading, Java Native Interface (JNI), and distributed systems including Kafka and Solace.
Skills
- Programming: C++, Java, Python, SQL, JavaScript
- Systems & Infrastructure: Distributed systems (Kafka, Solace), Databases, Operating Systems, Cloud (AWS, Azure)
- Performance Engineering: Multithreading, Java Native Interface (JNI), benchmarking (JMH)
- Machine Learning Systems: Model compression, retrieval-augmented generation (RAG), PyTorch
- Software Engineering Practices: System design, CI/CD, testing (JUnit, Mockito), Unix/Linux environments
Experience
Barclays Investment Bank (Statistical Modelling and Development)
Quant Dev Intern | New York, US | Jun 2025 – Aug 2025
- Improved p99 latency by 23% by profiling the Java quoting pipeline with JMH, diagnosing cross-socket NUMA traffic in a JNI-backed C++ library, and optimizing synchronization
- Increased throughput by 2.6× and cut message size by 50% by migrating inter-process communication from string-encoded messages to Protocol Buffers
- Designed a real-time event stream to convert yield-space quotes to price-space valuations to have a unified fair price
The D. E. Shaw Group (Middleware team)
Senior Member Technical | Hyderabad, India | Jan 2024 – Jul 2024
- Decreased ops workload by 30% by enhancing recovery of partial transaction log files and adding integrity checks against distributed replica warehouses
- Boosted trading middleware performance by 40% by optimizing cryptography implementation with OpenSSL and Java Native Interface, eliminating garbage generation
- Led the UI design of the intern evaluation portal and a UI overhaul of the monitoring tool based on user feedback
- Guided and mentored two summer interns through the completion of the internship
Member Technical | Hyderabad, India | Jun 2022 – Jan 2024
- Reduced start-up time of stateful Kafka applications by 93% by engineering a Kafka Application Recovery Protocol
- Co-presented Kafka Application Recovery Protocol at the Great International Developer Summit in Bengaluru
- Created a Slack bot that allows users to run custom scripts securely with user credentials through Slack commands, earning Runner-up at Infinity Hacks 2022, a company-wide 24-hour hackathon, among 350 participants
- Set up system infra such as load balancers, CNAMEs, Kerberos, CI/CD, and CRONs for 15+ services
Software Developer Intern | Hyderabad, India | May 2021 – Jul 2021
- Developed an all-in-one monitoring and debugging tool for Kafka users in the firm, providing a convenient way of analyzing topics, metrics, brokers, and consumer groups of Kafka clusters
