What I Can Do

Mostly, yes, and I work with clients in other countries and time zones. I am based in Mersin, Turkey (UTC+3); when the work requires it, we can also plan on-site meetings or working days.

It depends on the type of work: a fixed project price for work with a clear scope (an architecture review, for example), a day rate for work whose scope will become clear over time (€600 per day (excl. VAT)), and a fixed monthly fee for ongoing work (such as a fractional software architect, a fractional CTO or maintenance). For a fractional architect or fractional CTO the fee is from €2,400 per month for 1 day a week (excl. VAT); for maintenance it is updates, backup and monitoring checks, bug fixes and a monthly report included; from €600 per month for 1 day a month (excl. VAT), a 2-day tier is available; unused days do not roll over. Starting prices for the fixed-scope packages are listed on the packages page, in EUR and excluding VAT; I send the exact price in a written quote after our first call.

Half of the fee is paid upfront when the work starts, and the other half on delivery. Monthly agreements (fractional architect, fractional CTO, maintenance) are invoiced at the start of each month.

Yes. Every piece of work is invoiced in EUR by my company in Turkey, SDR Bilişim Hizmetleri Dijital Yazılım E-Ticaret Danışmanlığı İthalat İhracat Limited Şirketi.

If you want one, yes: scope, delivery, fees and confidentiality are set out in a written contract. For work where you do not want a contract, the written quote and your approval apply.

You do. Once payment is complete, the source code, the documentation and all rights to the software pass to you.

Yes. For work that requires me to access personal data, I sign a data processing agreement.

Yes. If you like, I can sign it before our first call, before we discuss any details of your project.

I can start a project with a clear scope within 1 week. We agree the exact date together on our first call.

I do, Umut Yerebakmaz, directly. I do not hand the work over to someone less experienced; you deal with the same person from the first call to delivery. For continuity I document every decision and technical detail and pass the knowledge on to your team, so the software does not depend on me.

Yes. As a fractional software architect I can work as part of your team: guiding architecture decisions, reviewing code, building the hard parts together and passing the knowledge on to the team. My aim is to strengthen your team, not to make it dependent on me.

I hand the software over to your team with its documentation, and run a knowledge transfer session that explains how the code and infrastructure work. If you like, we can continue with monthly support afterwards; I respond to support requests within 1 business day.

Because I work on my own, I do not offer 24/7 on-call cover or on-site hardware, network or cabling work; I respond to support requests within 1 business day. I do not hire out developers or assemble a large team at short notice; instead I work with your existing team as a fractional architect. I do not do advertising or social media management either. If an off-the-shelf package or platform will do the job, I tell you so on our first call.

The years and durations on this site are calculated from dates in my career: I started writing software in 1992 and founded my own agency in 2006. Testimonials come from real people and are published with their permission, word for word. The sample report uses a fictional company and is labelled as a sample. I do not publish a result as a number if the client has not allowed it or I have not measured it.
