Automation systems that save time, cut costs, and grow revenue.

Every system I build solves a real business problem, not just connects apps.

01

Lead Capture & Instant Response System

Every inquiry captured. Every lead answered in seconds, not hours. No more lost sales from slow follow-ups or missed messages. Your pipeline stays full, automatically.

02

Sales Follow-Up Automation

Leads go cold fast. I build sequences that follow up consistently until they convert, even outside business hours. Turn the leads you already have into paying customers.

03

Payment Collection, Reminders & Follow-Up Automation

Stop chasing invoices. I build systems that send invoices automatically, remind clients before and after due dates, escalate overdue accounts, and sync every payment to your books, so your cash flow stays healthy without the awkward conversations.

04

Hiring & Recruitment Automation

Stop drowning in applications. I automate your hiring pipeline: collect, filter, rank, and organize candidates so you fill roles in hours instead of weeks.

05

Customer Support System

Instant responses. 24/7 availability. Smart routing. I build systems that handle inquiries, resolve common issues, and escalate only what needs a human, reducing support costs while improving satisfaction.

06

Appointment & Booking Automation

Automated scheduling, confirmations, and reminders. Fewer no-shows, more booked slots, zero manual calendar management.

07

Client & Employee Onboarding

First impressions matter. I build automated onboarding flows that guide new clients or hires step-by-step, reducing training time, fewer mistakes, better retention.

08

Internal Operations & Workflow Automation

Eliminate bottlenecks in your day-to-day. Task routing, approvals, notifications, reporting. I wire it all together so your team moves faster with less manual coordination.

From bottleneck to automated in four steps.

1
Step 01

Discovery Call

We identify where your business is bleeding time and money. I map out the manual processes, disconnected tools, and missed opportunities.

2
Step 02

System Design

I architect a custom automation blueprint tailored to your workflows, tools, and goals, no cookie-cutter templates.

Step 03

Build & Test

I build, connect, and stress-test every automation before it touches your business. Clean. Reliable. Production-ready.

Step 04

Launch & Support

Your system goes live. I walk your team through everything and stay available to optimize and scale as your business grows.

The tech behind your automated business.

Every tool in its right place, wired together into systems that actually work.

What automation actually does
for your business.

Not theoretical. Not someday. These are the direct, measurable outcomes that automation delivers, starting in the first week.

Each project is a fully built n8n automation, designed to solve a specific business problem from end to end.

The Problem

The agency was losing 30–40% of inbound leads because nobody responded fast enough. Inquiries came from a website form, Facebook ads, and email, all landing in different places. By the time someone copied the lead into their CRM and replied, hours had passed. Competitors who responded faster were winning the deal.

The n8n Workflow

Lead Capture & Instant Response System workflow

How It Works

No matter where the lead comes in (web form, Facebook, or email), the workflow catches it instantly, creates a record, sends a personalized AI-generated response, and alerts the right person. The whole thing fires in under 60 seconds with zero human involvement.

Results

Lead response time: from 4–6 hours → under 60 seconds

Lead capture rate: from ~60% → 100% (zero lost leads)

Monthly qualified leads increased by 35%

Eliminated 15 hours/week of manual data entry

Estimated annual revenue recovered: $42,000+ from leads that would have gone cold

The Problem

The sales team had 200+ leads sitting in their CRM with no follow-up. Reps were too busy handling new inbound to nurture warm leads. Deals were falling through simply because nobody sent the second, third, or fourth touchpoint. The CEO estimated they were leaving $8,000–$12,000/month on the table.

The n8n Workflow

Sales Follow-Up Automation workflow

How It Works

Every morning at 9 AM, the system pulls leads that haven't been followed up on and sends the right email based on where they are in the sequence. Each message is AI-generated to feel personal, not templated. When a lead replies, the system immediately flags them as engaged and notifies the assigned rep. After four unanswered attempts, it gracefully moves on.

Results

22% of "dead" leads re-engaged within the first month

Average sales cycle shortened by 11 days

$9,400/month in recovered revenue from previously ignored leads

Reps saved 12+ hours/week on manual follow-up emails

Follow-up consistency went from ~40% → 100%

The Problem

The founder was doing great work but getting paid was a nightmare. She was manually creating invoices in Google Docs, emailing them as PDF attachments, and then tracking who paid in a spreadsheet. Clients regularly paid 15–30 days late. Some "forgot" entirely. She spent 6+ hours/month chasing payments and had $11,000 in outstanding receivables at any given time. The awkward "just following up on my invoice" emails were hurting client relationships.

The n8n Workflow

Payment Collection, Reminders & Follow-Up Automation workflow

How It Works

The moment a project milestone is hit or a project is marked complete, the system generates a Stripe invoice and sends a branded email with a one-click payment link. Before the due date, the client gets a friendly heads-up. On the due date, a direct notice. If they don't pay, reminders escalate gradually, polite at first, then firm. When payment lands, the client gets an automatic receipt, the books update, and the founder gets a Slack notification. At the end of every month, she receives a full financial summary without opening a single spreadsheet.

The founder went from dreading invoice day to never thinking about it. No more manually creating PDFs, no more copy-pasting payment details, no more uncomfortable follow-up emails. She told me the biggest win wasn't even the money. It was getting rid of the anxiety around asking to be paid.

Results

Average days to payment: from 27 days → 6 days

Outstanding receivables dropped from $11,000 → under $1,800

Late payments reduced by 82%

6+ hours/month of manual invoicing and chasing eliminated completely

Cash flow became predictable for the first time

Zero awkward payment conversations since launch

Automation running cost: ~$29/month (n8n Cloud + Stripe fees only on transactions)

The Problem

The founder and one HR assistant were managing hiring manually. Applications came through email, a Google Form, and LinkedIn messages. Screening took days. Good candidates accepted other offers while waiting. The HR assistant spent 20+ hours/week just organizing applicant data and sending status updates.

The n8n Workflow

Hiring & Recruitment Automation workflow

How It Works

Every application — whether from a form, email, or forwarded message — enters the same pipeline. AI reads the resume, scores the fit, and routes the candidate. Strong candidates get an interview link within minutes. Weaker fits get a respectful decline. The hiring manager only sees pre-qualified candidates with AI-generated summaries.

Results

Time to first response: from 3–5 days → under 10 minutes

HR admin workload cut by 70% (from 20 hrs/week → 6 hrs/week)

Qualified candidate drop-off reduced by 45%

Cost savings: ~$2,200/month in reduced HR hours

Hired 3 key roles in 2 weeks that previously took 6+ weeks each

The Problem

The support team of 3 was drowning in 150+ tickets/day — most of them repetitive: password resets, enrollment questions, refund policies, certificate downloads. Response time averaged 14 hours. Student satisfaction scores were dropping. Hiring a fourth support agent would cost $18,000+/year.

The n8n Workflow

Customer Support Automation workflow

How It Works

Every support inquiry is analyzed by AI the moment it arrives. Straightforward questions get answered instantly — no human needed. Complex or sensitive issues are routed to the team with full context and a suggested response draft. Angry or urgent messages are escalated immediately. Everything is logged automatically.

Results

62% of all tickets resolved automatically with zero human involvement

Average response time: from 14 hours → under 2 minutes

Support team workload reduced by 58%

Student satisfaction score improved from 3.2 → 4.6 out of 5

Saved the cost of hiring a 4th support agent: ~$18,000/year

Monthly operating cost of the automation: ~$47 (n8n Cloud + OpenAI API)

The Problem

The front desk was spending 3+ hours/day managing bookings: answering calls, sending confirmations, chasing no-shows, and rescheduling. No-show rate was 28%. Every missed appointment = ~$150 in lost revenue. At 40 missed appointments/month, that was $6,000 walking out the door.

The n8n Workflow

Calendly Trigger (new booking) OR Webhook (website booking form)

Airtable Node — log appointment details

Gmail Node — send branded confirmation email with prep instructions

Twilio SMS Node — send text confirmation

Schedule Trigger (48 hours before): Twilio SMS reminder + confirm/reschedule logic

"C" to confirm → update record

"R" to reschedule → send available slots

No reply → second reminder 24 hours before

Post-Appointment Trigger → Gmail thank-you + review request

IF recurring service → schedule next reminder in 4 weeks

How It Works

The moment someone books, they get a confirmation email and SMS. Two days before the appointment, they receive a reminder with a one-tap confirm or reschedule option. No-reply clients get a second nudge. After the visit, they receive a thank-you and review request. Recurring clients get automatic re-booking reminders. The front desk touches none of it.

Results

No-show rate: from 28% → 9%

Recovered ~$2,850/month in appointments that would have been missed

Front desk saved 3+ hours/day

Google review volume increased 4x

Rebooking rate for recurring services increased by 32%

The Problem

Onboarding a new client took 5–7 days of back-and-forth. The team had to manually send welcome emails, collect documents, set up folders, grant software access, and schedule the kickoff call. Steps got skipped. Documents got lost. Clients felt confused about what to do next. The firm was signing 6–8 new clients/month and struggling to keep up.

The n8n Workflow

Webhook — new client signed in CRM / Airtable

Gmail — send welcome email with onboarding checklist

Google Drive — auto-create client folder from template

Airtable — create onboarding tracker record

Delay 24 hours → IF documents uploaded?

No → send reminder email

Yes → OpenAI document review for completeness

Gmail — send access credentials

Calendly — send scheduling link for kickoff call

Slack — notify assigned accountant

Day 7 check-in email

Airtable update → status = "Onboarded" once kickoff complete

How It Works

The instant a client signs, everything fires automatically — welcome email, folder creation, document requests, reminders, access provisioning, and kickoff scheduling. AI checks submitted documents for completeness. The assigned accountant only gets involved when the client is fully prepped and ready.

Results

Onboarding time: from 5–7 days → 1.5 days average

Document collection completion rate: from 60% → 94%

Admin time per new client: from 4+ hours → 20 minutes

Zero onboarding steps missed since launch

Client satisfaction in first 30 days improved measurably

The Problem

Project requests came through email, Slack, and sometimes text messages. The ops manager spent the first 2 hours of every day just figuring out who's working on what, what's overdue, and what fell through the cracks. Tasks were tracked in a mix of Trello, Google Sheets, and Slack threads. Nothing connected. Deadlines were missed weekly.

The n8n Workflow

Slack Trigger OR Webhook (internal request form)

Code Node — parse request type, urgency, and assignee criteria

Airtable — create task record with priority and deadline

IF Node — route by project type: Design / Copy / Dev

Trello — create card in appropriate board/list

Slack DM — notify assignee with task details

Daily 5 PM: automated status summary to ops channel

Monday 9 AM: capacity report to leadership

On completion: Slack notify requester + log completion time to Airtable

How It Works

Any team member drops a request into Slack or the internal form. The system parses it, creates a tracked task, assigns it to the right team based on type, and notifies the assignee. Every afternoon, the ops channel gets an automated status report. Every Monday, leadership sees a capacity overview. When a task is done, the original requester gets notified.

Results

Ops manager reclaimed 10+ hours/week

Missed deadlines dropped by 74%

Average task completion time improved by 31%

Full visibility across 3 time zones

Eliminated the need for daily standup meetings

Estimated productivity gain: equivalent to adding 1 full-time hire
