Posthumous Messaging App
A "dead man's switch" app where users create messages — text, photos, videos, voice notes, documents — to be delivered to loved ones after death. Includes check-in system, trusted contacts, escalation logic, and memorial pages.
The entire backend runs on n8n in queue mode — 40+ workflows handling media processing, subscription management, push notifications, and account lifecycle. Real payments via Google Play Billing.

Imports leads from Google Sheets, uses Gemini AI to generate personalized 3-phase follow-up emails, sends via Gmail, updates CRM status, handles Cal.com booking triggers, and follows up on no-shows. Fully autonomous sales outreach.
Client Onboarding Automation

Three interconnected flows: (1) Extracts data from Fathom sales call transcripts, uses Gemini to parse info, generates PandaDoc contracts, tracks signatures, and updates CRM.

What I Work With
Tools and technologies I use to build production automation systems.
n8n
Expert — primary tool
From Concept to Production
I don't just build workflows — I architect systems that handle real-world complexity.
Understand the Business Problem
Map the actual process, identify bottlenecks and edge cases. What happens when things go wrong matters more than the happy path.
Design the Architecture
Sub-workflows for modularity, queue mode for scale, webhook patterns for integrations. Native nodes first, code nodes only when necessary.
Build with Error Handling First
Every webhook gets validated. Every API call has retry logic. Every failure triggers an alert. Production means handling the unexpected.
Ship and Monitor
Docker-based deployment, health checks, execution logging. If something breaks at 3 AM, the system tells me before the client notices.
