Principal, AI/ML Strategy & Delivery

A results-driven AI/ML Engineering Manager and Solution Architect with a unique background blending deep technical expertise with over a decade of leadership. My leadership philosophy is rooted in absolute transparency and is guided by a single, non-negotiable KPI: the success and growth of every individual on my team. I believe a leader's success is indivisible from their team's; if a single member is struggling, I consider it a collective challenge that reflects directly on my leadership and requires immediate, empathetic support and mentorship to resolve.

This people-first approach is powered by a "solutions surgeon" mindset—I focus on proactive problem-solving by engineering robust systems and processes that prevent headaches, rather than just treating them with band-aids. This requires a high degree of adaptability and a talent for navigating ambiguity, a skill demonstrated when I rapidly mastered a modern UI/UX stack from the ground up to build an entire team's training curriculum. Through expert prompt engineering, cross-functional collaboration and clear communication, I excel at translating complex, loosely defined requirements into actionable engineering plans that deliver high-quality, scalable solutions and foster a culture of proactive excellence.

PROJECTS

AI-Powered Recruiting Tool – (AI Job Matcher)

As a personal solo project, I owned the entire 0-to-1 product lifecycle for an intelligent job matching system. I engineered a full-stack application that allows users to upload a resume, which is then parsed to extract key skills and experience. The system queries job board APIs, filters for remote-only roles, and uses a matching algorithm to display only positions with a >70% alignment score. This project is a direct demonstration of my ability to independently build scalable recruiting tools. Note: This project was conceptualized, designed, developed, tested, debugged, and launched into production in a three day 0-1 time period.

Innovating on Career Pathing & People Development - (Flow AI Career Finder)

I conceptualized and built the Flow AI Career Finder from scratch to explore how AI can guide meaningful career development. The tool takes unstructured user inputs like personality traits, hobbies, and preferences, and outputs tailored career paths, including actionable steps needed to enter each field. This project showcases my deep curiosity about people development and my ability to apply first-principles thinking to build products that can fundamentally enhance company culture and empower people to do their best work. Note: This project was conceptualized, designed, developed, tested, debugged, and launched into production in a 15 hour 0-1 time period.
