AI & LLM Integration

AWS Bedrock (Nova Pro, Nemotron) for vision, extraction, and decision-making agents; Hugging Face models across text, image, audio, and video; a fine-tuned LLaMA with vector-database retrieval; Rasa and DialogFlow conversational systems; GPT-3.5 for structured generation.

Computer Vision & Machine Learning

CNN models for object and impact detection, trained in Keras/TensorFlow, converted to ONNX and CoreML for production and on-device inference. Benchmarked against ground truth, not just validation accuracy — including the domain-shift gap between training data and real sensor data.

Team Leadership & QA Tooling

Lead a team of annotators on a sports-tech client's ground-truth pipeline — and built the desktop tools they use every day (impactAnnotator, rangeAnnotator): per-user attribution, correction/verification workflows, and live physics feedback so a correction's effect is visible immediately instead of discovered downstream.

Cloud & Backend Infrastructure

AWS Lambda, DynamoDB, S3, SES, EC2, and ECR running a real production data pipeline end to end — ingest, process, align, score, report, alert. Flask and Express servers as the glue between browser automation, models, and storage.

Data Engineering at Scale

Structured extraction and deduplication pipelines across dozens of thousands of records — union-find merge logic, fingerprint-based dedup, incremental resume, and atomic writes with shrink-guards so a bad run can't silently destroy good data.

Browser Automation & Scraping

Playwright and Chrome extensions (Manifest V3) driving real, logged-in sessions — not APIs. Human-paced clicking, virtualized-list handling, session portability across machines, and recovery logic built from watching real automations fail and fixing the actual cause.

Mobile & On-Device AI

SwiftUI apps calling Bedrock directly from the device via Cognito temporary credentials — no backend server in the critical path — plus on-device WKWebView automation for the same tasks a server would otherwise drive.
