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.

The tool is actively used by project leads and clients to monitor quality metrics, track expert performance, and make data-driven decisions. Features include dynamic data processing, multi-stakeholder views, real-time quality tracking, and flexible filtering by project, date range, and expert. Engineered to handle thousands of audit records with sub-second rendering while maintaining enterprise-ready professional interfaces suitable for client presentations.

AI-Powered Recruiting Tool – (AI Job Matcher)

Owned the entire 0-to-1 product lifecycle for an intelligent job matching system. Engineered a full-stack application that parses uploaded resumes to extract key skills and experience, queries job board APIs, filters for remote-only roles, and uses a matching algorithm to display positions with >70% alignment score. Conceptualized, designed, developed, tested, debugged, and launched into production in a three-day sprint.

Flow AI Career Finder – AI-Powered Career Guidance

Conceptualized and built from scratch to explore how AI can guide meaningful career development.
