Rajnish Yadav

Rajnish Yadav is an Indian web developer, technical SEO specialist, and chess enthusiast. Frustrated by online chess clocks plagued with intrusive full-page ads, battery-draining bloatware, and inconsistent timer latency during fast-paced blitz and bullet games, Rajnish launched Chess Timer Digital to provide a free, reliable, and tournament-grade alternative.

Combining deep technical expertise in modern browser APIs (including the Web Audio API for latency-free auditory signals, the Screen Wake Lock API to prevent phones from going to sleep mid-game, and drift-corrected timing engines), Rajnish engineered Chess Timer Digital from the ground up to feel as responsive and trustworthy as a physical DGT tournament clock.

Beyond coding, Rajnish researches and writes extensively on official chess rules, tournament time controls, and clock mechanics. His analytical guides break down complex timing systems like Fischer Increment, Bronstein Delay, and USCF Simple Delay so club players, tournament directors, arbiters, and chess parents can easily understand and apply official regulations.
