Professional summary

I'm an Applied AI Engineer focused on building production-ready automations, AI agents, and integration systems across Operations, GTM/RevOps, finance-adjacent workflows, People Ops, and customer journeys.

What differentiates me is the combination of business context and technical execution. I don't just connect tools — I design systems around reliability, data integrity, controls, documentation, and measurable impact.

My background combines marketing and growth, business operations, and technical automation. I started in performance marketing and RevOps, working with lead generation, launches, funnels, CRM, paid media, lifecycle campaigns, and reporting. That gives me a strong understanding of how automation should connect to business outcomes such as conversion, retention, pipeline, revenue, cost control, and data quality.

Today I design systems with n8n, OpenAI / Claude-style LLMs, APIs, webhooks, Supabase / Postgres, Twilio, Shopify, Stripe, Airtable, Google Workspace, Apify, HubSpot, Jira, Deel, Toggl, and other business tools. My work includes multi-step workflows, AI classification, structured outputs, JSON schemas, prompt optimization, validation layers, data normalization, dashboards, SOPs, and production troubleshooting.
