Costel Apostol
Web Developer, Recruiter, and Director in Sweden
Hello, I'm Costel Apostol, founder of Norynth. We architect and secure the foundational technology stack for a new generation of applications—where AI logic, blockchain integrity, and robotic automation converge.
Our practice spans from core web architecture and symbiotic scripting to production smart contract development and robotics integration. Every solution is built on a security-first methodology, proven across 100+ blockchain audits securing over 50M+ in assets.
This hands-on experience is codified in our Smart Contract Security Playbook, a definitive guide for engineers and auditors.
I write and speak about the practical engineering challenges at this intersection—scaling systems, hardening protocols, and automating intelligently. Explore my technical articles above.
Based in Sweden, my path through astronomy, web development, and deep tech fuels a commitment to building not just with innovation, but with precision and reliability.
Let's architect the future with a solid foundation. Explore our work at Norynth.
