resume
I'm Aravind, a senior machine learning engineer in Bengaluru with 7+ years shipping autonomous agents, generative models, and real-time vision. Lately that has meant agentic workflows and small-model fine-tuning at KnowBe4, a knowledge graph for more than a million learners at LearnTube.ai, and an 8× faster inference path with NVIDIA DeepStream and TensorRT at DIATOZ. I build agents, language models, and computer vision systems.
what i do
Senior Machine Learning Engineer · KnowBe4
- AIDA: Architected agentic capabilities for automated phishing template generation and personalized training recommendations driven by employee RiskScore metrics.
- Agent security: Built a prompt-injection classifier on EmbeddingGemma with custom heads, then sped inference about 6× with vLLM and GPU acceleration.
- LangChain workflows: Shipped quiz generation from compliance documents and a hierarchical classifier covering 124 classes for training-module discovery.
- Red teaming: Built an autonomous agent that pentests other agents for prompt injection, jailbreaks, and guardrail bypasses. 1st place, KnowBe4 AI Hackathon Bengaluru 2026.
- Safety: Led evaluation pipelines and internal audits with the Claude Agent SDK and Claude Code.
Machine Learning Engineer · LearnTube.ai
- Built the AI systems behind a learning platform for 1,000,000+ learners, cutting curriculum generation from days to under 2 hours.
- Shipped a Neo4j knowledge graph connecting skills, objectives, and course videos into personalized pathways.
- Built an AI dubbing pipeline with Whisper, translation, and multilingual voice synthesis for regional Indian languages.
- Designed an NLP discovery engine with BERTopic, KeyBERT, and crawlers that ranked educational videos at sub-second latency.
- Shipped doubt solving, question generation, and summarization with GPT-4, Claude, LLaMA, and open models.
- Received the Best Employee Award (2022).
Senior SDE, Applied AI · DIATOZ Solutions
- Led a team of 4 on AI engines for E2Ehiring: resume extraction with LayoutLM and OCR, candidate matching, and interview scoring.
- Delivered an 8× inference speedup on real-time video by moving models to NVIDIA DeepStream, TensorRT, and Triton with FP16/INT8 quantization.
- Led a 3-engineer squad on Ezevision, a multi-camera traffic analytics product for detection, speed, and congestion.
- Built support agents in 4 Indian languages with RASA, Dialogflow, and BERT intent classifiers.
- Wrote deployment standards and mentored engineers on Docker, FastAPI, and GPU serving.
Project Management Trainee · Emerson Automation Solutions
- Supported delivery of the facility’s first High-Integrity Pressure Protection System (HIPPS), coordinating specifications, quality requirements, and expert reviews.
