Projects

Tech Startup Success Predictor

Hyperparameter-tuned classification models predicted Indian tech startup success with 82% accuracy. Engineered and analyzed features including seed lag, social media presence, and seed funding to identify factors associated with startup outcomes.

Python · pandas · scikit-learn · Matplotlib

BoilerExchange!

Built a deterministic stock exchange engine with price-time priority, event sourcing, partial fills, cancellations, and order modifications. Designed order matching logic to preserve FIFO execution within price levels and maintain consistent exchange state.

BoilerUpCommunications!

Built a terminal-based messaging system in Java with user authentication, persistent message history, friend and block functionality, and thread-safe concurrency. Supports multiple users while maintaining consistent shared state.

Java · concurrency · GUI systems

Custom Memory Allocator (Malloc)

Implemented a dynamic memory allocator in C using segregated free lists, block splitting, boundary tags, and constant-time coalescing. Managed heap growth with sbrk() and reused freed memory while reducing fragmentation.

Python · pandas · scikit-learn · Matplotlib

HTTP Server

Built a concurrent HTTP server in C/C++ supporting TCP sockets, authentication, static files, CGI execution, and dynamic directory browsing. Implemented process, thread-per-request, and thread-pool concurrency models.
