What I'm Into

I'm a Machine Learning Research Engineer working across LLM evaluation, multimodal AI, reinforcement learning, and robotics. My work spans simulation-based robot learning, imitation learning for contact-rich manipulation, and applied ML research β€” with a couple of publications in healthcare ML along the way. Currently sharpening Rust and Go, and always up for talking GPUs, deep learning systems, or open source.

πŸŽ“ MS Computer Science (STEM) β€” Clark University Β· ML for Robotics, 4.0 GPA β€” Worcester Polytechnic Institute


Featured Work

🦾 Robotics Sim & RL

Multi-task robotic simulation environments in MuJoCo modeling push-dynamics and forward kinematics. DDPG and A3C agents compared for continuous control across convergence, reward shaping, and policy robustness.

Python MuJoCo DDPG A3C

🎯 Imitation Learning (ACT)

Action Chunking Transformer for contact-rich peg-in-hole insertion β€” a UR10 arm trained in MuJoCo from expert demos, no RL reward signal. Multi-view RGB + pose + joint-state observation pipeline hit sub-millimeter precision.

PyTorch MuJoCo Imitation Learning

πŸ“ž AI Voice Agent Platform

Real-time autonomous voice agent using GPT-4o and Whisper ASR with Twilio for end-to-end call handling. Hybrid LLM + state-machine architecture with session memory and TTS caching for low-latency, reliable task completion.
