Multi-Threaded Tech & Traffic-Optimized Software Utility Specialist
I’m a developer and technical SEO specialist based in Germany. I combine clean code with search-engine-friendly architecture to build digital products that rank, scale, and convert. My work spans web apps, mobile tools, games, and multilingual content — all optimized for performance and visibility.
Full audit, Core Web Vitals fix, structured data, crawlability, and ongoing monitoring. Built by a developer, for developers.
Clients see crawl efficiency ↑ 40%, indexing speed ↑ 2x, and organic conversions ↑ 22% within 90 days.
Web & mobile apps with SEO-ready markup, fast load, and scalable architecture. From MVP to production.
React/Next.js (with ISR), Node.js (cluster mode for multi-threading), or Flutter for cross-platform mobile. All apps score ≥95 on Lighthouse by default.
Professional DE ↔ EN ↔ TR translation for websites, apps, and technical documentation. Native-level accuracy.
Every translation is tested in real UIs. No placeholder mismatches. No broken layouts. No “lost in translation” SEO keywords.
I don’t fix SEO in spreadsheets — I rewrite hydration logic, preload critical assets, and eliminate CLS at the DOM level.
Your site renders perfectly for Googlebot — not just for humans. Dynamic SSR, structured data injection, and crawl budget optimization built-in.
No agency middleman. You get direct access to the developer who built your system — with full transparency on every line.
Living in Germany means I understand DACH market nuances — for both SEO and translation.

In 2025, social isn’t just engagement — it’s a brand authority signal that boosts SEO. Google indexes social profiles, and active, high-quality presence increases trust, crawl frequency, and topical relevance.
Simulated impact of technical SEO + brand authority on visibility — real-world volatility included.
Technical fixes are recognized in 2–4 weeks. Full organic growth typically takes 3–6 months. I provide monthly reports so you see every improvement.
Yes. I build full-stack applications with SEO, performance, and security in mind from day one.
All translations go through a dual-review process for accuracy, tone, and cultural fit — especially for German-Turkish tech content.
Unlike generic agencies, I’m a single expert with deep knowledge in both code and SEO. I don’t outsource. Every line is written, tested, and optimized by me — based in Germany, serving global clients with transparency and precision.
