As answered by people managing SkillVee and Cert Decoder.
SkillVee's answer
SkillVee was created after seeing talented data professionals repeatedly struggle with hiring processes dominated by automated résumé filters and inconsistent interview expectations. The founders built SkillVee to give candidates a fair way to practice real interview scenarios, demonstrate their abilities, and connect with opportunities based on skill—not keywords. The platform joined Stanford StartX, gaining mentorship and support to bring this vision to life.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
SkillVee's answer
SkillVee is built using modern web and AI technologies, including:
Large Language Model–based AI interviewers
Python and Node.js for backend services
React for the frontend
PostgreSQL for data storage
AWS and Vercel for hosting and infrastructure
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
