I build the automation systems that run behind your business — from Google Workspace tools to AI agents and n8n workflows — replacing manual data entry, broken spreadsheet processes, and repetitive admin work with systems that hold up under real usage.
I built my track record automating Google Sheets and Workspace for growing teams — CRMs, dashboards, and reporting systems that replaced paid software entirely. I'm now extending that same engineering approach into AI agents and n8n orchestration, wiring OpenAI-driven logic directly into the workflows I already know how to build reliably. I hold Google's AI Professional Certificate and I'm actively taking on projects in this space.
𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱
- AI-Driven Workflows — OpenAI/GPT agents wired into backend systems and Sheets for data processing, prioritization, and reporting
- Workflow Orchestration — n8n and Python microservices for multi-app automation across your stack
- Google Workspace Systems — custom CRMs, sidebars, and web forms built entirely in Sheets + Apps Script: two-way sync, automated email/SMS/calendar actions, role-based dashboards
- Reporting & Dashboards — Klipfolio builds pulling live data from Stripe, NetSuite, HubSpot, GA4, and Google My Business for real-time KPI tracking
- API & Webhook Integrations — bi-directional sync across CRMs, e-commerce, and payment/ops tools (WooCommerce, HubSpot, Keap, Stripe, Slack)
- Data Pipelines & Scraping — automated collection (Python/Playwright, Apify) feeding clean, structured databases
𝗥𝗲𝗰𝗲𝗻𝘁 𝗪𝗼𝗿𝗸
- Crypto Regulatory Intelligence Radar: Built an RSS/alert monitoring system in n8n + Google Sheets + Slack for real-time regulatory tracking. Client feedback: "highly skilled... goes above and beyond to make things better." (5.0)
- AI Project Management Agent: Deployed a serverless agent (Google Apps Script + OpenAI) that analyzes Trello boards and generates prioritized "Mentor Reports" for a project team.
- CRM-in-a-Sheet: Built a full client-management system inside Google Sheets with a search sidebar, two-way sync, and automated email/SMS/calendar actions — replacing a paid CRM subscription.
- Live Revenue Dashboard: Connected Stripe billing data into Klipfolio to track weekly MRR, churned revenue, and cancellations.
- Real-Time E-Commerce Sync: Built a live webhook bridge between WooCommerce and Google Sheets, processing orders in real time with zero manual entry.
𝗧𝗲𝗰𝗵 𝗦𝘁𝗮𝗰𝗸
Automation & AI: n8n, OpenAI API, Make, Webhooks, Docker
Core: Python, JavaScript/Node.js, Google Apps Script, SQL
Dashboards & Reporting: Klipfolio, Matplotlib, pandas
APIs: HubSpot, Keap, WooCommerce, Stripe, Google Ads, Softr
𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗪𝗼𝗿𝗸 𝗪𝗶𝘁𝗵 𝗠𝗲
- Built inside your tools, not bolted on — no extra subscriptions, no new logins, no monthly fees eating your margin
- Engineering-first approach: modular, documented, fail-safe system design — not one-off scripts
- Clear, proactive communication with milestone updates, no chasing required
- A track record across 48 contracts and $50K+ delivered, at a 95% Job Success Score
If your operations depend on manual copy-pasting, fragile spreadsheets, or disconnected tools — or you're ready to add an AI layer on top of what you already have — send me a brief overview of the process and I'll tell you exactly how I'd automate it.
