Niek Van Der Maas is a seasoned founder and software engineer with 14 years of professional experience building web products and ad tech platforms from the Netherlands. He has repeatedly launched and scaled companies—founding or co-founding ventures such as Adperium, Atomx, Mininova, Undetect and Axe Media—demonstrating deep expertise in online advertising, product growth and monetization at scale. Technically hands‑on, Niek contributes to open-source browser automation projects (notably puppeteer-extra and ghost-cursor), where he implemented stealth plugins, human-like cursor behavior and service worker/UA hint support to evade detection and mimic real users. His work blends front-end polish (OBS-web, chatgpt-web) with pragmatic full‑stack JavaScript engineering and build/tooling improvements. An MSc in Software Technology underpins his pragmatic approach to shipping reliable systems, and he often pairs experimental open-source tooling with commercial productization. Less obvious: he combines advertising-scale ops knowledge (billions of monthly impressions) with low-level browser automation skills, a rare cross-section that informs both growth and anti-detection strategies.
