How would you describe the primary audience of your product?

SkillHacker.io's answer:

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

SkillHacker.io's answer:

SkillHacker is built on a modern, performance-focused stack: Nuxt.js for fast SSR/SSG & SEO, MongoDB for flexible question storage & progress tracking, Tailwind CSS for a responsive UI, and Docker for consistent, scalable deployments. Chosen for speed, maintainability, and rapid iteration - ensuring a smooth, reliable testing experience for developers worldwide.

Who are some of the biggest customers of your product?

SkillHacker.io's answer:

  • Independent developers preparing for FAANG interviews across 30+ countries
  • Early adopters from global LinkedIn and Discord tech communities
  • Self-taught engineers validating skills for career grade-ups
