Praveenkumar Biradar

Backend developer, embedded systems and network security engineer.

I build the whole path a sensor reading travels: the device, the gateway, the API, and the locked-down network that keeps it safe. Based in Bengaluru.

One gateway, four radios

My capstone project: a secure IoT gateway that takes telemetry from Wi-Fi, Bluetooth, Zigbee and LoRa devices and turns it into one clean REST API.

Plug-in protocolsEach radio sits behind its own adapter, so adding a new one never touches the core gateway.

Built for small devicesMQTT keeps messages light for constrained hardware on weak links.

Ready for appsTelemetry is normalized, stored in MongoDB, and served through REST endpoints.

Experience

Two roles at PES University, one on the code side and one on the infrastructure side.

Jan 2026 – Present

System Administrator, Network & Security

PES University, ISFCR
  • Administer 50+ Linux and Windows systems for research labs, holding 99%+ uptime through proactive monitoring.
  • Manage accounts, authentication and role-based access control with least-privilege rules across multi-user systems.
  • Configure firewall rules and VLAN segmentation, and harden operating systems with CIS benchmarks and patching.
  • Run isolated virtual machines and regular backup and disaster-recovery drills.
Jan 2025 – Present

Embedded Systems & Backend Intern

C-IoT, PES University
  • Built REST APIs that collect, validate and process data from many embedded devices at once.
  • Added authentication, input validation and secure data handling to device-facing endpoints.
  • Processed structured datasets with Python and SQL for analytics.
  • Shipped backend services in Docker for consistent, repeatable environments.

Projects

Backend-first work, from device telemetry to machine learning APIs.

Secure Multi-Protocol IoT Gateway

Capstone, 2025

Gateway that collects real-time telemetry from Raspberry Pi and Arduino nodes over four protocols, with a modular adapter design and REST access to the data.

Digital Addiction Relapse Prediction

2025

Express APIs ingest usage logs, a Python pipeline builds behavior features, and a Random Forest model (ROC-AUC 0.90) scores relapse risk in real time. Tuned with cross-validation and checked on precision and recall to handle class imbalance.
