Systems-First Engineering

Backend Security & Systems Engineer

I build robust backend systems, think in networking fundamentals, live in Linux, explore cybersecurity, and use AI to accelerate — not replace — engineering depth.

Devgna Vyas

Systems that hold up.

I am a backend and systems engineer specializing in robust architecture, network performance, and cybersecurity protocols.

My approach is first-principles driven: I believe in understanding standard RFC specifications, parsing data streams, evaluating packet flows, and studying systems failure paths before writing code. I utilize AI tools and automated agents as execution multipliers to accelerate design cycles, but keep complete logical ownership of architecture.

Cybersecurity is a serious area of focus for me, especially network intrusion, Linux kernels hardening, and local protocol validation. I build code that holds up under load and prevents vectors of abuse.

Formal Foundation.

Bachelor of Computer Applications (2023 — 2026)

CHARUSAT University

Smt. Chandaben Mohanbhai Patel Institute of Computer Applications (CMPICA)

Academic Standing

Graduated with a cumulative GPA of 8.25.

Core Focus

Computer Architecture, Operating Systems, Relational Databases, and Network Protocols.

Projects built with depth.

Featured Mobile Engineering Case Study

Same.Energy Android Client

An elegant, gesture-driven client built using Flutter and Dart for Same.Energy's semantic visual search engine. Replicates custom web-platform aesthetics in a highly-optimized mobile framework.

The Challenge

Translate a complex semantic image query web search into a physics-driven responsive mobile grid, handling asynchronous image pre-fetching and encrypted local caching on strict memory boundaries.

What Was Built

A full client integrating masonry visual grids, curated user feeds, and collections folders. It leverages physics-based scrolling and custom gestures with full-screen viewer overlays.

The Architecture

Decoupled Clean Architecture. Employs Riverpod for predictable reactive state boundaries, Dio client for network request intercepts/timeouts, GoRouter for type-safe navigations, and secure local keychain storage.

Biometric IoT Systems Study

Smart Attendance System

A secure, centralized, multi-factor attendance verification platform designed for academic institutions to eliminate proxy marking and location spoofing.

The Architecture

Built a high-performance backend using Go and Gin, leveraging PostgreSQL for durable records and Redis for fast transient session state. Facilitated real-time bidirectional communication via Gorilla WebSockets for live attendance dashboard updates.

Tri-Factor Verification

Engineered a robust anti-spoofing pipeline combining rapidly rotating HMAC-SHA256 signed QR codes, on-device Google ML Kit face liveness checks (blink/smile detection), and BLE beacon proximity handshakes via a cross-platform Flutter application.

Security & Cryptography

Implemented RS256 asymmetric JWT token signing, Argon2id password hashing, and mDNS/UDP LAN auto-discovery. Designed an audit-ready architecture with automated PDF/Excel report generation ensuring tamper-evident attendance validation.

Peer-to-Peer Networking Utility

ez-drop

A zero-cost, serverless, peer-to-peer secure file and text transfer utility. Connect directly browser-to-browser with no limits and no intermediate storage.

The Architecture

Leverages WebRTC data channels for high-bandwidth, direct connection streams between browsers. Implements public IP hashing with Mosquitto MQTT for seamless local network auto-discovery.

Game Modding & IPC

BeatBlocks Control

A Fabric mod for Minecraft Java 1.21 that provides in-game control for Spotify with overlay, HUD, and hotkeys. Communicates locally with a Spicetify bridge without needing API keys.

The Architecture

Built using the Fabric Modloader with a custom Java WebSocket client to securely communicate with the local Spicetify WebSocket server, providing real-time playback state sync.

HERMES: Design and Deployment of a Hybrid AI/ML Network Security System on ARM Clusters for Edge Environments

Arpankumar G. Raval & Devgna Vyas

Presented at 7th International Conference on Soft Computing and Its Engineering Applications (icSoftComp 2025)

📅 Dec 2025 📚 Springer CCIS Volume 🏛️ CHARUSAT Research Lab

Abstract: Designed and deployed a lightweight, cooperative intrusion detection system (IDS) combining signature-based filtering with a quantized 3-layer Deep Neural Network (DNN) classifier. Optimized specifically to run inline on low-power ARM edge nodes, securing local edge topologies without compute bottlenecks.


Evaluation Metric Benchmarked Outcome
Detection Accuracy 94.7% (Novel attack identification)
Low-Power Envelope 4.2W per ARM active node
Packet Throughput 15 kpps inline detection
Energy Efficiency 67% reduction compared to standard x86 IDS

— Fuegoleon Vermillion

I believe in thinking from first principles — understanding data flow, control paths, and failure modes before writing a single line of code. I value performance, clarity, and maintainability over novelty. Given sufficient time and access, I focus on understanding the problem deeply and then building reliable, maintainable solutions.
