Senior Technical Project Manager with 11+ years delivering SaaS, AI, and custom web/mobile products end-to-end. I lead a small delivery team and run projects across the full stack — from discovery and scoping through sprint execution, QA, and launch. What I'm best at: - Technical PM for SaaS and AI products. I've shipped MVPs and full platforms across real estate AI, ERP, E-commerce, agentic workflows, and AI-augmented PM tooling. Comfortable in technical conversations because I came up through development before moving into delivery leadership. - Stakeholder coordination in matrixed and ambiguous environments. I translate fuzzy intent into clear scope, owners, and dates, and produce decision-ready summaries for senior leadership rather than raw status updates. - AI-augmented delivery. Daily Claude and Copilot user. I build and use Claude Projects with custom skills for PM, requirements elicitation, and vendor evaluation work. This is core to how I operate, not a buzzword. Tooling I use daily: Jira, Confluence, Slack, Notion, Linear, Figma, Google Workspace, GitHub, M365 (SharePoint, Teams, Planner). Comfortable adapting to whatever stack a team already runs on. Domains I've delivered in: Real estate tech, fintech, ERP (Odoo), e-commerce, healthcare websites, marketplaces, AI agents. Engagement style: structured, low-bureaucracy, fast feedback loops.
