hi

if you want the longer version, my resume is here. a few writeups live in the posts.

anyways, i'm aravind, a senior machine learning engineer. i like building agents, small language models, and computer vision systems — then checking that they still behave when someone tries to break them.

i'm at KnowBe4, on AIDA: agentic phishing simulations, training recommendations from employee risk, and a prompt-injection classifier that pushed inference throughput about 6×. before that i built learning systems at LearnTube.ai for over a million people, including a Neo4j graph of skills and courses, and real-time video pipelines at DIATOZ — an 8× speedup with NVIDIA DeepStream and TensorRT.

some things i've built: an autonomous red-teaming agent that pentests other agents (our team won the KnowBe4 AI Hackathon, Bengaluru 2026), IllustratED (history, science, and math as pictures for kids), WhiZED (a Socratic tutor on Gemma), and Juno (spoken English practice). i also like the unglamorous part: classifiers that stay fast, graphs that stay useful, and guardrails that actually hold.

outside of work i keep coming back to teaching — language, pictures, kids who don't get a patient tutor otherwise.

thanks!
