Passionate and adaptable Computer Science graduate with a strong interest in cybersecurity, mobile/IoT technologies, and AI-powered automation. I’ve led teams and group projects multiple times, consistently taking initiative and delivering results. I’m confident in my ability to explain complex technical concepts clearly, making me a strong bridge between engineering and business teams. I thrive in fast-paced, collaborative environments and am eager to contribute to Visa’s mission by supporting secure product development, optimizing workflows, and driving innovation. I take pride in being really good at what I do, and I’m always looking for ways to grow and help my team succeed.

Building a C-like Compiler (C-Simple) April 2025:

Developed a lexer and parser using context-free grammars and PLY for a custom C-like language., Designed and implemented an Abstract Syntax Tree (AST) for arithmetic, conditional, and loop constructs., Built a working Intermediate Representation (IR) supporting type inference, control flow, and expression evaluation., Performed Local Value Numbering (LVN) and constant folding optimizations., Wrote multiple modules for CFG generation, symbol tables, and IR translation. 

Pthreads and Synchronization April 2025:

Implemented multithreaded producer-consumer pattern with semaphores and mutexes., Debugged and resolved race conditions and deadlocks in concurrent environments. 

Page Replacement Simulator May 2025:

Simulated FIFO, LRU, and Clock page replacement algorithms., Visualized and compared page fault rates under varying memory sizes and access patterns., This required deep understanding of virtual memory and OS-level memory management.

Embedded Sensor Interface June 2025: Wrote software to poll and process data from mock sensors (e.g., temperature, motion)., Developed interrupt-based input handling and event-driven control logic., Real-world embedded application focus, relevant to IoT and firmware development roles.
