Berkay Pekersoy
Full-Stack Web
Developer.
I build AI-powered web products that rank on search engines and get recommended by ChatGPT, Gemini, and Google. From GEO optimization to LLM integration — I help businesses win the AI era.
Sound Familiar?
Most clients come to me frustrated because the industry is full of unnecessary technical jargon and broken promises.
Communication Blackhole
No response to emails for days. You never know the status of your project.
Endless Revisions
You requested something simple, but the result is complex and doesn't even work.
Visual Garbage Dump
The site looks amazing, but nobody buys. Because consumer psychology was neglected.
AI Blindness
Your customers no longer just use Google — they use ChatGPT, Gemini, and Google AI Overviews. Your old-gen site isn't even on their radar.
My Approach
I don't make excuses. I deliver results.
Clear Strategy
Before writing code, I get to the root of the problem. What does the user want? What are you selling? We reduce friction to zero.
Seamless Communication
No drowning in technical jargon. You will always know transparently what I do, why I do it, and the current stage of your project.
Flawless Execution
I build fast-loading, mobile-friendly, aesthetic, and most importantly "converting" infrastructures. Not just pretty, but hard-working products.
Generative Engine Optimization (GEO)
Traditional SEO is dying. I structure your site semantically (GEO) so AIs like ChatGPT, Gemini, Perplexity, and Google AI Overviews will scrape and recommend to your customers.
Proofs
Talk is cheap.
Here is my work.
Not just showcase visuals. Real solutions for real problems.

FAQ
Questions you have in mind.
The first step is a free discovery call. I learn about your project, goals, and budget. Then I prepare a proposal with a clear scope and timeline. Once approved, development begins and I keep you informed at every stage. Delivery typically takes 2–4 weeks depending on the project.
Every project has a different scope. A fixed price list means paying for features you don't need. With custom quotes, you pay for exactly what you need — nothing more, nothing less.
As of 2025, ChatGPT, Gemini, Perplexity, and Google AI Overviews process billions of queries. These platforms crawl semantically well-structured content and recommend it to users. Through Schema.org markup, semantic HTML, and GEO-focused content architecture, I get your site included in both traditional search and AI recommendation engines.
Yes. Every project includes a defined number of revision rounds after delivery. The scope is clearly established before work begins, so there are no surprises. Minor corrections and fine-tuning are covered during the revision process.
30 days of free technical support is included after delivery. For long-term maintenance, updates, or new feature needs, a monthly support package is also available.
Agencies route work through multiple people: sales team, project manager, developer. As a developer who works with you directly, communication friction drops to zero. You get faster decisions, a more transparent process, and work with someone who actually owns the code.
