Case studies

Rather than describe what I do, let me show it.

Everything below is real: the work, the hours, the outcomes. I do not inflate the numbers, because you already know your own business will not change overnight.

01

Client work

KRCPACK

Food and printed packaging

Client

The off-the-shelf portal cost ten times as much. We built theirs in forty hours.

A packaging manufacturer that needed an internal portal could not make any ready-made system fit. The quotes were more than ten times my cost and came with a per-user licence. We built the portal in forty hours, then rescued a website that was down half the day in another fifteen.

SMS Chemical

Chemical manufacturing

Client

E-commerce from nothing: site, marketplaces, warehouse and courier in one flow.

A newly founded chemical manufacturer wanted to move into e-commerce. We built the whole thing: a bespoke storefront, marketplace and courier integrations, automatic stock and price synchronisation, and a packing flow in the warehouse.

Stock and prices sync to the marketplaces on their own

Systems I run myself

These are not client projects. But the strongest evidence a consultant can offer is doing the same thing with their own resources.

Lofux

E-commerce · print on demand

My own brand

I run the same kind of system I am proposing to you, with my own resources.

Lofux is my own e-commerce brand. I built and run everything in it myself, from the product system, accounting integrations, operations planning and the print workflow. It is the most honest evidence a consultant can offer.

Web server

Server administration and DevOps

My own infrastructure

A single server carrying forty sites, kept running by me for years.

My own projects and the sites of former clients live on this server. Setup, migration, hardening, certificates, backups and monitoring are all mine. This is what sits behind the sentence "I can handle the server side too".

Hosted and administered on one server
40 sites
With certificates that renew themselves

Privacy notice

Last updated: 24 September 2026

This site carries no advertising trackers, behavioural profiling or third-party marketing cookies. Personal data is processed only when you fill in the contact form, and only so that I can reply to you. Google Analytics, used for visit statistics, runs only if you accept it.

Who is responsible

Uğur Yetkil is the controller for the personal data processed on this site. The business operates from Türkiye; you can reach the controller through any of the contact channels on this site.

What is collected

Only what you type into the contact form: your name, company, email address, phone number if you give one, the tier you are interested in, and your message.

There is no sign-in, membership or payment on this site, so nothing else is collected.

Why it is processed

The sole purpose is to reply to your enquiry and run the conversation that follows. This data is not added to a marketing list, not used for newsletters and never sold to third parties.

Legal basis

Processing rests on Article 6(1)(b) GDPR, as steps taken at your request before entering into a contract, and on Article 6(1)(f) as a legitimate interest. For enquiries from Turkey, Article 5/2-f of the KVKK applies.

Who it is shared with

Form submissions are delivered through an email service and a messaging service used for notification. These providers are used solely to deliver the message; your data is not shared for advertising.

Cloudflare Turnstile is used for bot protection. Turnstile does not build a profile that identifies you.

If you accept measurement, visit data is passed to Google through Google Analytics. If you decline, that transfer never happens.

How long it is kept

If your enquiry does not lead anywhere, the record is kept for at most twelve months and then deleted. If we begin working together, the data is kept for the duration of the contract and any statutory retention period that applies.

Cookies and visit measurement

Visit counts are measured with Cloudflare Web Analytics. That counter uses no cookies, writes nothing to your browser and does not identify you, so it runs without asking for consent.

Google Analytics 4 is also used. Because Google Analytics sets cookies, it loads only if you accept it. Until you do, the script is never added to the page; declining takes no action on your part, as that is already the default state.

If you accept, the pages you visit, the link that brought you here, your approximate location and your device and browser details are sent to Google. Your name, your email address and anything you type into the form never enter this measurement. Google may also process this data on servers outside the European Union.

You can change your choice at any time: the “Measurement preference” link at the foot of the page reopens the consent strip. When you decline, measurement stops and the cookies Google Analytics left behind are deleted from your browser.

Apart from that, your browser may store a functional value such as your language preference; it does not identify you.

Your rights

Under the GDPR and the KVKK you may ask what data is held about you, request correction or erasure, object to processing, and ask for your data to be transferred.

To exercise any of these, write to the email address on this site; your request is answered within thirty days at the latest.

Data inside client projects

Delivering the service may require technical access to data held in a client’s systems. The confidentiality clause in my standard service agreement applies, and I will also sign the GDPR or KVKK data-processing agreement your company uses.
