Summary
👤
Senior🎓
Top SchoolMartin Kluska is a pragmatic CTO and serial founder based in Prague with over a decade of hands-on experience building web and mobile products, from MFA/IAM enterprise systems to education tools and consumer apps. He blends full-stack fluency (Laravel, Next.js/React, Redis, Elasticsearch, Kubernetes) with product-minded leadership, preferring small, efficient teams that ship affordable, user-focused solutions. Martin has a track record of founding and exiting ventures—including a craft brewery—and running product studios (RedTag, Certisys) that deliver both client and proprietary platforms like Canvastera and GITRIX. He contributes to open-source tooling (e.g., work on chunked uploads supporting DropZone and resumable.js) and is comfortable owning architecture, development, and operations across the stack. Notably, his career began in Flash in 2006 and evolved through mobile and cloud-native systems, giving him an uncommon breadth from legacy web to modern infra.
