Individual developers across all levels and stacks: frontend, backend, mobile, game dev, systems, and DevOps. SkillHacker serves English-speaking engineers preparing for technical interviews, validating skills for grade-ups, or benchmarking promotion readiness. Our audience chooses active, role-specific testing over passive tutorials to measure progress against peer averages, pinpoint knowledge gaps, and build data-driven confidence before career-defining evaluations.
SkillHacker.io's answer
SkillHacker was born from personal frustration: I couldn't find any tool to objectively measure my theoretical dev knowledge. Scrolling through 100+ JS questions on GitHub gave no feedback, no progress tracking, no way to know "am I actually ready?" So I built SkillHacker - a platform where developers test actively, see real benchmarks vs. peers, and measure growth. No more guessing. Just data-driven skill validation for interviews and grade-ups.
