Sound familiar?

Excel everywhere

Price lists, customer data, versions. All in competing spreadsheets.

Data in 5 tools

CRM, Dropbox, email, WhatsApp. Every process needs copy-paste.

No in-house tech team

You know software would help. But who builds it? Who vets vendors? Who says what's worth the investment?

It's been like this for years

Processes that 'somehow work'. Until someone quits. Then it gets expensive.

The usual options. And why they don't fit.

Whether you need software built or help deciding what to buy. These are your typical choices.

The Agency

Let me loop in our account manager to schedule a kickoff.

The Reality

  • Every question needs a meeting. Every change needs sign-off.
  • You pay for layers. The developer sees a fraction.

Layers slow you down.

The budget freelancer

Sorry, been swamped. I'll get to it next week.

The Reality

  • Low rates, high volume. You're project #6 on their list.
  • At those rates, documentation isn't included. Neither is handover.

Cheap now. Expensive later.

There's a third way.

Direct. Transparent. Reliable.

One contact. One system. No drama.

One point of contact

I build it myself. I advise myself. Questions answered in minutes, not meetings.

I understand your business

Business + tech background. I ask 'What?' and 'Why?' first, before I solve 'How?'

Clear pricing. Always.

Binding price after analysis. Consulting on a daily basis. No hidden extras. You know what you pay.

The knowledge stays with you

Whether code or recommendations: documented, explained, yours. No vendor lock-in to me.

One employee. The entire sales operation.

A real estate company sells apartments as investment properties through external consultants. The process ran on WhatsApp, email, and multiple Excel spreadsheets. One person worked full-time just to maintain documents in Dropbox and coordinate with consultants. Commissions were calculated manually, reservations managed through back-and-forth messages. As volume grew, it became clear: this won't hold up. Today, the entire process runs on one platform with automatic commission calculation, multi-stage approval workflows, and a client portal.

About me

Business & Technology. Application Lead. Not just a developer.

Most recently, I scaled a cloud cost management system from prototype to production-ready: 12+ integrations, 70% reduction in unused licenses, cost analysis in hours instead of weeks. I understand both sides: business and code.
