I've been writing other people's projects for 18 years.

I started in 2009. Since then, always as part of a team, always building things together.

During this time, I always worked on my own projects too. But I never talked about them. Maybe it's the ego of a developer who grew up from scratch - the "let the code speak" mentality.

That's changing now.

From now on, I'll tell the story of each project I've built. The story, the technical decisions, the successes and the failures.

First stop: 850santral.com

A one-person company. Just me.

Problem 1: Need a marketing team

The product is ready, but who will sell it? Should I post a job ad, read CVs, do interviews?

I didn't. I coded the team.

• Scout - Instead of typing "Izmir dental clinic" on Google Maps and collecting contact info one by one, this agent scans thousands of businesses and ranks them by score
• Outreach - Instead of writing "Hello, we wanted to reach out..." emails to 500 people separately, this agent sends personalized first messages to each lead
• Follow-up - Instead of tracking dates in Excel wondering "did they see my email?", this agent sends automatic reminders after 3 days and routes responses to Closer
• Closer - Instead of picking up the phone saying "Hello, I'm calling from 850santral...", this agent directly calls the business, explains the product, and books demo appointments if interested

Problem 2: Customers arrived, now need support

Marketing worked, customers started coming in. Emails, questions, support requests...

Same question again: Should I post a job ad? Hire support staff?

I didn't. I coded the support team too.

• Reads incoming emails, categorizes them, responds directly to most
• Answers the support line, talks to customers, provides instant solutions to known issues
• When it can't solve something on its own, it texts me: "This customer's issue is different, take a look"

Works 24/7. Doesn't get sick. Doesn't ask for vacation.

Problem 3: Advertising and promotion... still thinking

Now it's time for ad management. Google Ads, Meta, campaign optimization...

But this time I'm stopping to think.

Agencies are expensive. Managing it myself takes too much time. What if I coded this too?

An agent that creates campaigns, optimizes by budget, tracks performance, and shuts down low-performing ads...

Haven't done it yet. But it's spinning in my head:

How can I do this at lower cost and higher performance outside of Google and Meta? What alternative channels are there? How do I balance organic growth with paid?

This team hasn't been coded yet. Maybe it'll be one of the next projects.

So what does this automation give me?

I spend an average of 1-2 hours a day on 850santral. Sometimes none at all. The agents are working, I just check when I get notifications.

The rest of my time I'm developing new projects, exploring different opportunities.

Before, I would have needed a team of 3-4 people to do this. Now I'm running it alone.

Roles are changing

Now I'm thinking: Is this stealing jobs from marketers and support teams, or is it expanding the job description of developers?

I think neither. Roles are changing.

Developers are no longer just writing code - they're designing business processes. Others are becoming strategists who manage these agents.

I'll tell that story next - the heart of 850santral.
