Technical Project Manager | AI/ML Delivery & Solution Architecture

AI/ML delivery leader and Solution Architect combining hands-on engineering with more than a decade of operations leadership. I take over enterprise data programs that are behind, over budget, or losing client confidence, and I thrive in fast paced environments where requirements change mid-delivery. I work the problem to its actual cause rather than patching the symptom, then build the pipelines, QA systems, and tooling that keep it fixed, so quality becomes a gate before delivery instead of a finding after it.

When I see a process that can be improved, I do not wait to be asked. I build the fix and hand it over as something the team can run without me. When something goes wrong, including my own calls, I say so early, document what happened, and correct it on the record. That combination of transparency and proactive problem-solving 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 translate complex, loosely defined requirements into actionable engineering plans that deliver high-quality, scalable solutions.

PROJECTS

Contributor Qualification System (Talent Intelligence Platform)

Built a working web application that turns production quality reviews into searchable skill evidence, seeded with 63,630 contributors, 169 projects, 361 skills, and 32,843 historical quality reviews. Delivery managers map skills to project stages, bulk-review entire rosters in seconds, and search for contributors by proven skill evidence rather than self-reported tags. Packaged for a controlled internal pilot with role-based sign-in, and paired with a talent capability strategy for discovering and validating expertise that already exists in a contributor network before recruiting externally.

QA Dashboard Generator (Enterprise Analytics Platform)

Built a production-grade React application that transforms raw QA export data into interactive dashboards for AI training operations. 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. The tool takes unstructured user inputs like personality traits, hobbies, and preferences, and outputs tailored career paths with actionable steps needed to enter each field. Integrated with Anthropic's Claude AI for intelligent conversational guidance. Launched into production in a 15-hour 0-1 sprint.

Lazy Eye Training Games (Vision Therapy Platform)

Developed a comprehensive web-based vision therapy platform for individuals with amblyopia (lazy eye). Features dichoptic therapy modes using red-blue 3D glasses, multiple game types (Tetris, Breakout, Target Tracking), and medical-grade considerations including session timers and progressive difficulty scaling. Built with advanced JavaScript ES6+ featuring object-oriented architecture, collision detection algorithms, and 60fps game loops. WCAG 2.1 AA compliant with cross-browser compatibility.

Global Workforce Availability Application

Developed a web application solving communication challenges in global remote workforce management. Enables employees to set and update weekly availability with real-time tracking, automated reporting, and secure Google Cloud authentication. Built with Firebase and BigQuery for data persistence, reducing communication friction across time zones.

Sustainability Data Visualization System

Designed and implemented a comprehensive data visualization system for Southern New Hampshire University's sustainability initiatives. Transformed raw environmental data into actionable insights using Python, SQL, and Power BI. Created interactive dashboards for energy consumption, waste management, and carbon footprint tracking. Contributed to the university achieving Silver status in sustainability rankings.
