My Time atSIG

I worked at Susquehanna International Group for my last co-op. It was fun, got to learn a lot, even though my work was very intern-like (non-consequential) but still don't wanna get too in the weeds

Here is a brief overview of the projects I have worked on:

C++ Metrics Publisher

Developed a C++ protocol metrics publisher to tail multiple log files, parsing key-value pairs with custom decoders and generating data frames for 5.8 billion+ messages per day. The system provided real-time performance monitoring for trading gateways.

Python Orchestration Layer

Built a Python orchestration layer with C++ bindings to aggregate data frames, transform them to JSON, and stream real-time metrics to Elasticsearch and Grafana dashboards. This enabled sub-second latency monitoring for trading operations.

Concurrent Python Kafka Consumer

Developed a concurrent Python Kafka consumer leveraging asyncio and multiprocessing to process 500+ million messages in 5 minutes, achieving a 9x speed improvement. Implemented intelligent partitioning and robust error handling for continuous market operation.

FastAPI Alert Proxy

Created a Python FastAPI proxy server integrating OpenTelemetry alerts with an internal messaging platform via RESTful API. Reduced alert-to-notification latency by 60% through asynchronous processing and contextual enrichment.
