Drawing the stack…
Automation Engineer · Claude & Codex Operator

Build once. Runs forever.

Repetitive work quietly drains your time, money, and growth. I design and build the automations, AI agents, web apps, and integrations that take it off your plate — running 24/7 so you save hours, cut costs, and scale without hiring. I work as a partner who learns your business, not a contractor ticking boxes.

Tools I build with

// Operating principle I don't automate tasks. I architect the systems that run the operation — built once, running forever, without supervision.

Capabilities

What I automate & build for you

Automation is the core — backed by the apps, sites, and integrations that run it. Four ways I solve real problems and take work off your plate.

SVC.01

Workflow Automation

Repetitive manual work is slowing your team down. I build n8n, Make, and Zapier systems that take it over — SMS sequences, data pipelines, call monitoring, PPC, content repurposing, multi-step logic — running 24/7 without supervision, so your people focus on the work that actually grows the business.

SVC.02

AI Agents & Marketing Brain

You can't be everywhere at once. I build AI agents that learn your business and handle it for you — customer-service bots, knowledge-base assistants, and a marketing "brain" that delivers daily plans to Slack. Feed it your data; it only gets smarter.

SVC.03

Web Apps, Sites & Pages

Need a site, store, or tool that actually converts? I build full-stack web apps, landing pages, marketing sites, and custom Shopify stores — fast, on-brand, and conversion-built — plus complete Klaviyo email flows (welcome, recovery, post-purchase) that recover lost sales on autopilot.

SVC.04

Integrations & Technical Ops

When your tools don't talk to each other, things slip through the cracks. I connect your stack — CRMs, Shopify, Google Ads, Slack, Twilio, databases — and handle the technical ops (scraping, reporting, monitoring, clean-up) that quietly keep everything running.

// The stack

Everything I build with

The real toolkit behind the systems above, grouped by what it does — and I adapt to whatever your operation already runs on.

Real production systems — scannable at a glance. Click any card for the problem, the solution and the result.

Different tools, same outcome: I build on whatever fits the job — n8n, Make, Zapier, Claude, or custom code — and adapt to the stack you already run. Every build below is a custom solution shaped around a specific business problem.

Profile

Architect of systems, not tasks.

I'm a business-automation engineer. My core strength is automation — workflows, AI agents, and integrations — plus the web apps, sites, and tools that run alongside them. I build with AI and direct it: I scope the system, the AI drafts it, and I review, test, and ship — so you get production-grade results in days, not months. What matters most isn't the tools, though — it's that I take the time to understand your business and shape the solution around it. Stack: n8n, Make, Zapier, Claude, Supabase, Twilio, Klaviyo, Shopify, Python, Next.js — plus whatever your operation needs.

Claude & Codex operator — I direct the AI agents and ship production-grade systems in days, not weeks. Built on a subscription, not per-API-call billing — which keeps your costs down and predictable.
