Traceability Protocol Deployed on Vercel

HiveTrace

A honey supply-chain provenance system designed for Indian apiaries. Provides role-based interfaces for beekeepers, certified testing laboratories, processors, and distributors, linked together with consumer QR verification.

Problem Solved

Conventional supply chain demos confuse immutability with authenticity. HiveTrace strictly separates certified laboratory purity analysis from tamper-evident batch lifecycle events.

What Was Built

Next.js 16 App Router application with role-based auth, dynamic QR scanning at `/scan`, mock batch state transitions, and responsive consumer verification dashboards.

Origin: Sundarbans Mangrove ReserveTamper-Evident Hash Sealed

Harvested by Green Valley Apiary cooperative. Lab certified at NBB regional testing facility with 100% floral pollen consistency.

MOISTURE CONTENT17.2% (Norm < 20%)

HMF ANALYSIS14.8 mg/kg

SEPARATION OF CLAIMS ARCHITECTURETamper Proofing

• Tamper Evident: SHA-256 seal guarantees historic logs cannot be altered unnoticed.

• Product Authenticity: Explicitly accredited to accredited laboratory spectroscopy.

04 // Beyond the Interface

Curious about what makes things work.

I'm Sushovan Halder, a Computer Science and Engineering student at RKMGEC who learns best by experimenting with real projects.

I enjoy moving between the visible side of software—interfaces, websites, and user experiences—and the underlying systems, protocols, and developer tools that power them. This portfolio is a living record of that process: things I've built, experiments I'm testing, and technical directions I'm learning.

Academic GroundingStatus: Undergraduate Student

Ramkrishna Mahato Government Engineering College (RKMGEC)

B.Tech in Computer Science and Engineering

My coursework and self-directed engineering emphasize programming fundamentals, data structures & algorithms, operating systems, and network architectures.

I prioritize verified implementation over superficial credentials. Rather than claiming premature production readiness, every project in this portfolio specifies its exact scope, tested assumptions, and real technologies.

ENGINEERING PHILOSOPHY"Build things from the bottom up to truly understand how they behave when something breaks."

Active Inquiries

Current Technical Explorations.

4 Focus Vectors

Active Focus

Systems & Linux Engineering

Delving into Debian distribution architecture, live-boot environments, and unprivileged namespace isolation for sandboxed code execution.

Core Question

"How minimal can an unprivileged Linux live environment be while remaining complete for developers?"

Learning

Security & Cryptography

Investigating end-to-end encrypted protocol handshakes, forward secrecy guarantees, and digital steganography statistical triage.

Core Question

"What deterministic indicators reliably identify tampering or hidden data before applying ML models?"

Building

Full-Stack Web Engineering

Building reactive, high-performance web applications with Next.js, TypeScript, and clean modular component systems.

Core Question

"How can zero-runtime CSS patterns and server-side pipelines maximize real-world rendering throughput?"

Exploring

Local AI & Automation

Experimenting with local inference engines like Ollama for offline forensic analysis and automated developer workflow tooling.

Core Question

"How effectively can localized small language models assist in deterministic security auditing?"
