About Me
I’m Efe, a full-stack developer and technical strategist based in Istanbul, currently leading the e-commerce infrastructure of Prosatz, one of Europe’s top printing technology firms. I specialize in building scalable, high-performance systems for enterprise-level operations . Alongside my full-time roles, I co-founded Copartner, a curated freelance collective that unites the independent creatives and developers I've worked with throughout my career under one brand. The aim was simple: to give freelance projects a consistent and credible identity and potentially evolve into a full agency in the future.
Backed by a strong foundation in algorithms and analytical thinking, I approach problem-solving with precision and business impact in mind. I’m also advancing my strategic and managerial skills through the Executive MBA program at Istanbul Technical University.
Whether working with fast-growing startups or global-scale enterprises, I bridge the gap between clean code, functional design, and business intelligence to build meaningful, measurable digital products.

My journey began with a Mathematics degree from Akdeniz University, where I also freelanced as a graphic designer and interned as a junior developer at Bioexpo fairs. Upon graduation, I joined Bioexpo full-time, maintaining and optimizing their digital presence.
In 2023, I moved to Istanbul to join Endostel HR as front-end developer of enuygunbakici.com, a B2B+B2C career platform. I co-architected the system, which scaled from 50K to 400K+ organic monthly users within six months — making it the market leader in its niche.
In 2025, I joined Prosatz to lead development on their enterprise e-commerce systems using a modern tech stack: Shopify Hydrogen + React + Laravel, integrated with custom APIs and backend media infrastructure tailored to print industry logistics.
Work Experience
- Developed a custom Shopify storefront using Hydrogen (React + Remix), enabling highly dynamic and performant e-commerce experiences tailored for the printing industry.
- Utilized Tailwind CSS to craft pixel-perfect responsive layouts with component-based architecture for long-term scalability.
- Built a modular CMS system using Laravel and PHP to manage media assets (product photos, banners, etc.) and dynamic page content, integrated seamlessly with the storefront.
- Designed and implemented custom B2B workflows including customer-specific pricing, exclusive product access, and order automation tools, enhancing enterprise-level buyer experience.
- Collaborated with marketing and product teams to ensure technical SEO compliance and smooth data handovers between systems.
- Engineered the backend using Pure PHP and MySQL, and the frontend with HTML5, CSS3, and jQuery, optimized for high concurrency and minimal latency.
- Refactored the HTML structure into fully semantic, SEO-optimized markup, increasing organic traffic from ~50K to over 400K monthly users within 6 months.
- Designed and prototyped the mobile application in Figma, covering over 120 unique screens with user flows and UI systems prepared for cross-platform development.
- Developed and tested RESTful APIs for mobile integration, encompassing over 70 interconnected database tables, ensured accurate data delivery and versioned documentation for developers.
- Conducted extensive stress testing, page load time optimization, and caching strategies to support heavy traffic while maintaining system integrity.
- Managed an existing website built with a custom WordPress theme engine, handling regular maintenance and updates.
- Learned backend logic under mentorship while leading the technical SEO integration using tools like Google Search Console, structured data (Schema.org), and performance audits.
- Implemented keyword-driven structural improvements and collaborated on enhancing Core Web Vitals performance.
- Ensured content reliability and system consistency during major expo events with thousands of visitors.
Copartner
A project I’m proud to co-found, built on trust, shared vision, and creative freedom.
What is Copartner?
Copartner is not your typical agency. It’s a digital media collective designed to bring together talented freelancers under one unified brand — without compromising their independence.
How did it all begin?
For years, we’ve been taking on freelance projects, often collaborating with others as if we were already part of the same team. One of us handled the front-end, another the backend — and just like that, we shipped full-scale digital products. We realized: the structure was already there, just without a name.
So, what did you build?
We created a home for all those collaborations. A brand freelancers could attach to their work — not as employees, but as creative equals. Copartner is a shared identity, a trusted label, and a space to evolve.
Why build it this way?
Because something changes when people feel ownership. The projects we’ve built under Copartner became more thoughtful, more conceptual, and more collaborative. The quality improved, not because we imposed structure, but because we gave it meaning.
What’s your role in Copartner?
I co-founded and lead the initiative. I designed its visual identity, developed the website, and helped shape its internal culture and voice. But more than that, I helped transform a way of working into a platform others can proudly call their own.
What’s the outcome?
Copartner isn’t just an agency. It’s a creative ecosystem. A community of people who believe in the power of shared vision — and who now have the infrastructure to bring those visions to life.
