SharpSkill

My story (and why I built SharpSkill) I’m a freelance tech consultant. Between two client missions, there’s always the same stressful moment: the interview prep. You have 24–48 hours to refresh a technology, remember fundamentals, and somehow sound sharp and confident in front of a client. But every existing tool I found was either: • too algorithmic (LeetCode, HackerEarth), • too academic, • deprecated, • or simply not aligned with real-world interviews. In consulting interviews, we don’t do FAANG-style whiteboard puzzles. Clients expect something else: a practical discussion, architectural reasoning, fundamentals, and the ability to explain trade-offs clearly. No tool helped me prepare fast and credibly for that. So I created my own preparation workflow: realistic interview simulations, flashcards, and technical tests that feel like actual client assessments. It helped me land missions at 600€/day with far less stress. That personal workflow became SharpSkill. A focused, no-bullshit platform for developers who want to prepare efficiently, not spend weeks grinding algorithms. SharpSkill now offers: • Interview simulators (HR + technical) inspired by real client missions • Flashcards to quickly refresh a tech stack • Technical tests No long courses. No filler content. Just the essentials you need to sound sharp, structured, and credible during a client interview. This project started from a personal need. Now I’d love your feedback to make it the best preparation tool for tech developers. Happy to answer every question here.
