A startup founded by Rich Miner, Co-founder of Android. Working at the cutting edge of Artificial Intelligence for digital handwriting synthesis and intelligent search. As a Deep Learning & NLP Engineer, I built production-grade AI systems across the full Machine Learning lifecycle: ▸ Transformer & Deep Learning: Implemented TrInk (EMNLP 2025) a state-of-the-art handwriting generation model featuring MDN output layers, cross-attention multi-writer style conditioning, Gaussian memory masks, and polar coordinate tokenization. Researched adaptive Bézier curve segmentation as an alternative tokenization strategy with continuous 10D feature vectors for transformer inputs. ▸ TensorRT Optimization: Converted the PyTorch model to ONNX + TensorRT FP16, achieving ~2× GPU inference speedup on NVIDIA RTX 4500 Ada. Diagnosed and resolved FP16 numerical precision instabilities in autoregressive generation pipelines — real-world Deep Learning deployment engineering. ▸ ML Model Serving: Built a production FastAPI server on GCP with PostgreSQL LRU caching, adaptive batch GPU processing, and word-length-based step scheduling. Fully integrated with Android and web clients via RESTful APIs — complete Machine Learning DevOps lifecycle. ▸ NLP & LLM Engineering: Developed an AI-powered semantic search system using ChromaDB vector database and OpenAI LLMs for intelligent, context-aware notebook content retrieval — applied NLP and LLM engineering at the product level. ▸ Data Science Pipeline: Engineered a large-scale Amazon Mechanical Turk (AMT) data collection system with boto3 automation, Google Drive/Sheets tracking, and multi-phase worker recruitment for curating a handwriting dataset at scale.

Deployed and engineered large-scale, production-grade Artificial Intelligence and Machine Learning systems in a high-security, real-world environment: ▸ LLM Infrastructure & Scalable Serving: Deployed and managed a 5-server vLLM cluster (NVIDIA RTX 4500 Ada) serving Llama 3.1 8B with PagedAttention KV cache optimization, FP8 quantization, prefix caching, and Prometheus/Grafana monitoring — enterprise-scale LLM Engineer work in production. ▸ Distributed Multi-GPU AI: Implemented distributed inference for LLaMA 3.2 70B across 4 NVIDIA GPUs using distributed-llama.cpp and vLLM with Layer 3 load balancing for real-time streaming token generation. ▸ AI Chatbot & RAG System: Architected a full-stack FastAPI RAG AI Chatbot with Qdrant vector database, vLLM backend, cross-encoder reranking, RAGAS + F1/EM evaluation, JWT auth, and a React frontend with conversation management. Improved answer accuracy from 70% to 80%+ in an air-gapped, offline environment. ▸ LLM Fine-Tuning & NLP: Fine-tuned LLaMA 3.2, DeepSeek, Qwen2.5, and GPT using QLoRA on custom PDF datasets for domain-specific NLP question-answering. Deployed 70B GGUF models offline via llama.cpp on A100 GPUs with Open WebUI. ▸ Deep Learning & Computer Vision: Trained YOLOv8/v9 for real-time object detection; built LSTM models on 1M-record synthetic datasets for time series forecasting (75%→89% accuracy); applied SHAP explainability to anomaly detection for defense systems. ▸ Data Science & Geospatial AI: Engineered hybrid LangChain + LangGraph pipelines combining vector and graph databases; built geospatial ML pipelines using QGIS for flight path simulation.
