Current Focus
Real-Time Operating Systems, System Security, and Applied Cryptography at TU Delft. Building secure-by-design embedded systems that operate under real-world constraints.
Systems-First Builder
Gokul Raj S
Bridging physical sensing and digital intelligence through secure, embedded systems at scale.
MSc Computer & Embedded Systems Engineering at TU Delft. Former Software Engineer at Juniper Networks. I architect production systems where hardware reliability meets software scale.
Professional Foundation
2+ years at Juniper Networks shipping mobile insights and diagnosis, network validation automation, and distributed system features. Promoted to SWE2 for impact on enterprise-scale network tooling.
Engineering Philosophy
Security is not a feature—it's an architecture decision. I build systems where cryptographic guarantees and operational resilience are structural, not afterthoughts.
End-to-End Systems Engineering
I help teams move from hardware prototype to production-grade software. Specializing in secure IoT architecture, embedded diagnostics, and validation automation that reduces manual effort by 60%+.
