I build practical software across mobile UX, backend reliability, static-first web apps, Linux tooling, and network/security systems. My work usually starts from the parts that decide whether a product survives real usage: authentication, sessions, deployment constraints, offline behavior, data flow, performance, and failure paths.
I am a backend and systems engineer and a co-author of a Springer CCIS conference paper on lightweight network intrusion detection for ARM edge environments.
Note
Operating principle: keep the interface simple, keep the system understandable, and make the engineering strong enough that the user never has to think about it.

SPRINGER CCIS icSoftComp 2025 EDGE SECURITY
Publication: Springer CCIS · icSoftComp 2025
Authors: Arpankumar G. Raval, Devgna Vyas
Theme: Lightweight network intrusion detection for low-power edge environments
HERMES combines a rule-based filtering layer with compact ML inference for ARM-based edge nodes. The work focuses on making intrusion detection practical under real deployment constraints: limited power budget, small hardware, network throughput, and model efficiency.
| Signal | Detail |
|---|---|
| Domain | Network intrusion detection, edge security, ARM systems |
| Core idea | Hybrid signature filtering + compact ML classifier |
| Platform focus | Low-power ARM / edge cluster environments |
| Publication venue | Soft Computing and Its Engineering Applications, Springer CCIS |
