I got bored studying for certs from endless PDFs. So I built NixBolt. Gamified certification prep with real market data, demand scores, salary ranges so you study the cert that actually gets you hired. What's inside: → AWS, Azure, Kubernetes, Terraform, Kafka, CISSP and more → XP, streaks, levels, mastery mode → Wrong-answer retry loop until you actually know it → Market intelligence showing what companies are hiring for → Works on any device, no download needed Built solo. Free to try!
