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.

Embedded SystemsSecurity & CryptographySoftware at Scale

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.

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.
