How it started

Two earlier eras that built the foundation — long-term SEO operating period and the years of early experiments before that.
2011 — 2025 · Network Services Company (confidential)

SEO & Growth Lead

Fourteen-year operating period leading organic traffic growth and product marketing for an international network services company.

Long-term focus on scalable site structures, content systems, and search visibility — turning SEO from experimentation into sustained product growth. July 2025 marked the transition into the new independent phase.

Early internet experiments

The early years were full of experimentation — forums, blogs, traffic-driven content sites, small online tools. Some projects focused on communities, others on search traffic and monetization experiments.

One of the earliest browser-based puzzle websites was launched around 2014, long before the current PuzzleFree project. Many of these early projects are no longer online, but they shaped everything that came later.

Affiliate sites, monetized web projects, and small fast-moving experiments built practical intuition about traffic, search behavior, and online business.
