01 — About

Systems engineering
where hardware meets the network.

I'm a final-semester PhD scholar in Computer Science & Engineering at IIT Kharagpur, in the Smart Wireless Applications & Networking (SWAN) Lab under Prof. Sudip Misra, and a former Research Intern at Samsung R&D Institute India, Bangalore. My work lives in the resource-constrained middle where embedded hardware, networks and machine learning meet.

Over 6+ years I've taken systems from breadboard to production: HTTP and a full TLS 1.3 handshake carried over LoRa for remote and ad-hoc networks, a 4×4 and 8x8 LoRa MIMO testbed for higher throughput, condition monitoring for overhead cranes and rotating machinery, and a lightweight blockchain running on a microcontroller. Several are patented and some are in production.

I've led small teams on consulting and research projects for Tata Steel, Bokaro Steel Plant, Haldia Water Services, and CPHEEO resulting in end-to-end systems and their field validation. My aim always has been and still remains to build systems that are reliable, low-power, and genuinely useful to the people who depend on them.

02 — What I work on

Six problems I keep coming back to.

Different projects, one throughline: making capable systems run on tiny, far-flung, power-starved hardware — and keeping them secure and maintainable once they ship.

LPWAN & LoRa Systems

Long-range, low-power links that carry more than telemetry — HTTP and TLS over LoRa, message handling, interference management, and MIMO for throughput.

LoRaRFM95WSX1262FHSSTLS 1.3

Edge Systems

Running AI inference on the edge. Staged model deployment for constrained devices on and single-board computers instead of relying on the Cloud to avoid latency and ensure security.

Industrial IoT & Condition Monitoring

Retrofitting legacy plant equipment with modern sensing — vibration, temperature, electrical and gas monitoring wired into Industry 4.0/5.0 dashboards.

MQTTModbusPLCGrafana

Secure Cyber-Physical Systems

Trust at the edge — end-to-end TLS over constrained links, real-time intrusion detection and actuation, and tamper-proof logging via lightweight on-device blockchain.

TLS 1.3BlockchainIDS

Full-Stack IoT

From schematic and firmware to REST APIs, dashboards and deployment. Custom PCBs on one end, containerised cloud on the other — and everything that connects them.

03 — Selected work

Systems that left the lab.

A few projects I've led or built end-to-end. Most are patented; several run in production at industrial sites and municipal utilities.

Industrial deployment In production

EOT Crane Condition Monitoring

Tata Steel Downstream Products Ltd — Jamshedpur, India

Led a team of four to build and deploy a full-stack condition-monitoring system for Electric Overhead Travelling cranes — real-time vibration, temperature and electrical sensing streamed to plant-floor dashboards. Patented and running in production.

HTTP & TLS over LoRa

Siia - SWAN Lab, IIT Kharagpur, India

A transparent proxy that accepts ordinary HTTPS from a Wi-Fi device, carries the request across a LoRa backhaul, and completes a full end-to-end TLS 1.3 handshake at the far end — unlocking the web for remote and ad-hoc networks with no cellular coverage.

LoRa MIMO Testbed

4×4 spatial multiplexing — SWAN Lab, IIT Kharagpur, India

Designed and evaluated a 4×4 MIMO system for LoRa that uses spatial multiplexing to exchange parallel data streams, pushing effective throughput well past a single link while keeping LoRa's low-power profile intact.

Water Distribution Pressure Monitoring

Haldia Water Services · CPHEEO, Govt. of India

A solar-powered, remotely configurable IoT node that streams domestic water-pipe pressure to the cloud for ML analysis — built for a CPHEEO / Ministry of Housing & Urban Affairs project and deployed in the field.
