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 currently a BCA student at CHARUSAT / CMPICA, Batch of 2026, and a co-author of a Springer CCIS conference paper on lightweight network intrusion detection for ARM edge environments.

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.

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.

• Building static-first web apps that deploy cleanly on GitHub Pages.
• Improving PWA/WebRTC utilities with simpler UI and faster connection logic.
• Keeping Tutoring live as a practical service page for programming and exam preparation.
• Exploring Linux systems, security tooling, and low-overhead network defense.
• Refining Flutter client architecture for fast, polished Android experiences.

Open to: internships, freelance web/mobile work, backend systems, academic software, security-focused engineering discussions, tutoring enquiries, and practical project collaborations.
