Case studies
I'm Jonathan Bayo. I build lead research, outreach, CRM and reporting systems in n8n, Python and Claude for founders and small teams. 14 of them are below, with how each one runs and what came out of it.

A daily n8n job that checks every other workflow, tells a stall from a weekly schedule, re-fires what it can, flags what needs money, and only emails a person when it can't fix the problem itself.
n8n · n8n public API · Supabase · Microsoft Graph mail · GitHub Actions
Picks the highest priority leads from Supabase, has Claude write a 45 second script, sends it to Visla to render and saves the video link back on the lead.
n8n · Claude API · Visla API · Supabase · HMAC auth
Every Monday it reads a list of target companies, searches for fresh signals like funding, hiring and leadership changes, scores them and pushes the hot ones into the CRM.
n8n · Airtable · Tavily search · Jina search · GoHighLevel
Takes a scored lead from the monitor, has Claude write a two sentence problem statement for the company, builds the full CRM record and pushes it to GoHighLevel. About three seconds a lead.
n8n · Claude API · GoHighLevel · Webhooks · JavaScript code nodes
Searches Google Maps for a business type in a city, scrapes each website for contact details, has Claude pull out what the business does and writes a clean lead list to Google Sheets.
n8n · Apify (Google Places) · Python · Claude API · Google Sheets
Staff ask a plain question about company documents, policies and contracts and get an answer with the source cited. Runs on the company's own servers.
Python (FastAPI) · Weaviate · LangChain · Claude API · Docker
Scrapes candidate profiles for a role, enriches them with public data, scores fit against the job with AI and pushes only the qualified ones into Airtable with a summary for the recruiter.
Make.com · Apify · OpenAI API · Airtable · Slack
A signed form kicks off the contract, the e-signature, the project folder, the Slack channel, the CRM deal and the welcome email. About 60 seconds, no hand offs.
n8n · Google Forms · DocuSign · Google Drive · Slack
On the first of the month it pulls portfolio numbers from Sheets, has Claude write the month's narrative, builds each investor's report with their own allocation and sends it.
n8n · Google Sheets · Claude API · Gmail
After an event, every attendee gets a follow up within 24 hours that refers to the sessions they actually attended. The most engaged ones get flagged for a personal call.

Nothing else in this category. The featured ones above may have it.
I've spent the past year as the automation and back end engineer for a B2B sales intelligence company, building the research pipeline, the CRM tooling and the multi-tenant product you see above. Alongside that I take on builds for founders and small teams: outreach, lead research, onboarding, reporting.
I work in n8n and Python, use Claude where a step needs judgment, and keep everything in your own accounts so nothing depends on me being around.
We start with what's taking too long. I map the steps, pick the smallest system that removes them and build it, with Claude where a step needs judgment.
Everything logs its own runs, never sends the same thing twice and fails loudly instead of quietly. You get the workflows, the credentials in your accounts and a short doc on how it runs and what to do when it stops. Most builds take a week or two. If it's going to take longer I'll say so before we start.
Tell me what's taking too long. Most things can be built in a week or two.
