Summary
A results-driven PhD Candidate and highly proficient Full-Stack Developer with 6 years of backend experience (Python) and 3 years of frontend experience (React). My background is defined by a deep commitment to the entire Software Development Lifecycle (SDLC), including CI/CD pipeline optimization and enhancing software quality through meticulous runtime analysis on APIs. Currently, my research at RMIT University specializes in Reinforcement Learning (RL), focusing on the integration of Large Language Models (LLMs) for Agentic RL. I aim to bridge advanced data structures and algorithms expertise with cutting-edge AI research to develop intelligent, scalable, and reliable AI systems with tangible engineering impact.
