PAID CLIENT AI AUTOMATION EXPERIENCE

  1. RetailBox | AI Lead Enrichment & HubSpot Automation | Case study

    Jul 2026 | Paid client engagement | Live; ongoing maintenance

    • Built an n8n webhook workflow that processes new HubSpot contacts, retrieves company website content, sends it to Gemini for structured enrichment, applies lead-priority rules, and updates the CRM automatically.
    • Client reported sales outreach beginning within about 5 minutes of contact creation, down from hours or sometimes days of manual company research.
    • Implemented HTTP/API integrations, JavaScript parsing, and field mapping; continues to maintain the client workflow.
  2. MugDevs | AI CV Screening & Shortlisting | Case study

    Apr-May 2026 | Paid client engagement | Maintenance as needed; idle between hiring rounds

    • Automated intake from Google Drive: extract readable PDF text, use Gemini to score against role-specific criteria, and write candidate rankings, justification, and review status to Google Sheets.
    • Client-reported screening of 70+ CVs fell from roughly one week to minutes; consistent criteria replaced varying manual reviewer judgments.
    • Routed unsupported and scanned files for manual review rather than producing unreliable candidate scores.
  3. Hollow Technologies | AI Support Email Triage & Drafting | Case study

    Apr 2026 | Paid client engagement | Completed handover

    • Built an n8n/Gmail workflow using Gemini to classify incoming support messages, log priority and summaries in Google Sheets, and create contextual reply drafts in the original Gmail threads.
    • For a 60-80 email/day inbox, the client reported response times falling from an 18-hour average to minutes; staff retained review and final-send control.
    • Separated classification and drafting into distinct model calls, paced requests for rate limits, and delivered the workflow and documentation to the client.

SELECTED INDEPENDENT AUTOMATION WORKFLOWS

  1. Overdue Invoice Chaser | Scheduled Finance Automation | Case study

    Self-initiated case study | Not a paid client deployment

    • Designed a daily n8n workflow combining QuickBooks, Gmail, Airtable, and Slack: invoice follow-ups at days 1/3/7, human escalation at day 14, audit logging, retries, and a separate Slack failure-alert workflow.
    • Tested failure alerts with broken credentials and documented known gaps, including missed-day handling and duplicate reminders on manual reruns.
  2. Lead Qualification & Follow-Up | Form-to-Email Automation | Case study

    • Connected Google Forms, Gmail, and Google Sheets to acknowledge inbound leads immediately, filter personal/disposable email domains, and log eligible company contacts.
  3. AI Content Repurposing | Multi-Channel Publishing Workflow | Case study

    • Built an n8n workflow to fetch article content, generate LinkedIn, short-form social, and email drafts with Gemini, and archive structured outputs in Google Sheets.

INDEPENDENT AI APPLICATION ENGINEERING

  1. ParseHQ | AI Invoice Extraction & Verification | Case study

    Personal full-stack project | Private development/testing, not a client deployment

    • Building a Next.js/TypeScript system that extracts invoice data with Gemini/OpenAI, validates structured results with Zod, and flags arithmetic mismatches for human review.
    • Implemented OCR-based source references, multi-tenant access checks, and transaction-safe trial quota enforcement; currently testing core functionality.
