AI Automation Engineer · Founder, TheSolvers AI

I build production AI systems that run without babysitting.

Reliable n8n and AI automation that reads, decides, and acts across a business's tools, so the manual work disappears and the team gets its hours back. Deterministic where it can be, AI where it needs judgment, a human on anything that matters.

/ Selected work

Two live production systems, in depth
Finance operations

The accounts payable pipeline, running itself.

A CFO advisory firm · two companies, 100+ staff each
Problem

An operations team hand-entered every incoming invoice into accounting, across two companies. Slow, inconsistent, and easy to miss one.

Built

An n8n pipeline that watches the inbox, extracts every field with AI, validates it against the firm's rules, posts a draft into QuickBooks, and logs every action to an audit trail.

Result
750+/mo

invoices processed with zero manual entry, nothing dropped, fully traceable.

Customer communication

An AI concierge that answers, drafts, and follows up on its own.

A luxury travel company · lean 7-person team
Problem

Guest communication was the single biggest time sink for a small team, across long, high-touch trip-planning cycles on email and WhatsApp.

Built

An AI agent system that classifies each inbound message, pulls answers from a searchable knowledge base and past threads, drafts a reply for approval, and chases stalled conversations automatically.

Result
~40 hrs/mo

of manual guest communication taken off a lean team, freeing them for the work that needs a human.

WhatsApp · live in production

Simba — 1:1 guest concierge

A WhatsApp bot on Twilio that answers customer questions in real time, pulling from a searchable knowledge base. Running live today.

Autonomous agent

Follow-up agent

Scans for conversations and tasks that stalled, drafts and sends the follow-up on its own, and stops the moment each one is resolved.

Data pipeline · retail

Product data scraper

Pulled 380+ fields per product into Airtable for a large retail catalog, deduplicated by key and orchestrated end to end in n8n.

Monitoring · e-commerce

Campaign monitor

Watches email-marketing campaigns across multiple accounts and fires an instant alert the moment a metric crosses a threshold.

/ How I build

Why these systems stay reliable
01

Deterministic first

Fixed rules and code handle the ~90% of work that shouldn't be left to a model. Predictable, testable, cheap.

02

AI for judgment

The model only touches the calls that genuinely need reasoning, with its output checked before anything is saved.

03

Human in the loop

Anything that matters, a payment, a reply, a submission, waits for your approval. The system supports the team, it doesn't go rogue.
