👤 About Me

Building things that bridge software and the physical world.
Focused on embedded systems, IoT architectures, and real-time sensor integration —
working across bare-metal C to high-level Python, React, and everything in between.

  • 🔧 Embedded Systems — bare-metal, RTOS, microcontroller firmware
  • 📡 IoT — MQTT, Wi-Fi, BLE, Blynk, edge computing
  • 🔬 Sensor Integration — I2C, SPI, UART communication stacks
  • 🌐 Web & Backend — React, Node.js, MongoDB, Firebase
  • 📍 Odisha, India — open to remote collaboration

🚀 Featured Projects

🛰️ Wireless Solar Farm Monitor
Two ESP32s talking over ESP-NOW, five sensors deep, 11 OLED screens you can flip through like a control-room dashboard — no Wi-Fi, no cloud, just raw peer-to-peer telemetry.

🔐 RFID Access Control + OLED
MFRC522 reader gatekeeping an L298N-driven motor, with an SSD1306 OLED that roasts or welcomes you in Hindi/English depending on whose card you scan.

⏰ ESP8266 Smart Clock, EMO Edition
Started as a clock, grew animated EMO-robot eyes, picked up live weather from OpenWeatherMap, and now pings notifications pushed from a Python/Termux script on Android.

🏠 Layered Home Security System
IR + TTP223 touch + MQ-2 gas + magnetic door sensor, all fused into one LCD-driven system, built iteratively sensor by sensor until it could watch an entire room.

🩹 Smart Pressure-Ulcer Prevention
The most architecturally ambitious build yet — FPGA edge-AI inference, STM32H7 running FreeRTOS, wrapped in an animated web landing page.

🖨️ Parametric Keychain Generator
CadQuery scripts that turn a name into a 3D-printable STL — custom nameplates and Transformer-styled keychains, generated, not modeled by hand.

🚦 Traffic Light Systems, Every Which Way
Four-road sequential logic, a 12-LED grid variant, button-cycled and switch-per-signal versions — the same intersection reimagined four different ways.

📷 Raspberry Pi Camera Guide
A beginner-friendly repo untangling the Pi 3 vs 4 vs 5 camera differences, paired with sensor-and-LED starter examples for people just getting off the ground with a Pi.
