};- ⚙️ I work the whole stack — from PCB/KiCad hardware design and bare-metal STM32/ESP-IDF firmware, up through Yocto-based custom Linux, to on-device ML.
- 🏭 My firmware runs in the field: an industrial Anti-Collision System I built is deployed at Tata Steel BlueScope.
- 🐧 Currently building eOS — a Yocto/OpenEmbedded Linux distribution for the Raspberry Pi 5 with A/B RAUC OTA, an MQTT service bus, and a Qt6/QML UI.
- 🎙️ Into on-device voice & ML — wake-word detection, Whisper STT, Piper TTS, and multi-mic fusion running on the edge in Rust.

🐧 Embedded Systems Engineer — Elipse, Hyderabad · May 2026 – Present
Building eOS, Elipse's custom Yocto/OpenEmbedded Linux distro for the Raspberry Pi 5 (A/B RAUC OTA rootfs, MQTT service bus, SQLite, Qt6/QML UI). Authored Yocto recipes across the
meta-eoslayer; designedsystemdservices, D-Bus interfaces, and a hardened Mosquitto MQTT broker. Built a generic Rust sensor-fusion framework and an on-device voice subsystem (transfer-learned wake-word → Whisper STT → Piper TTS, ONNX viatract). Wrote ESP-IDF firmware for ESP32 satellites with BLE provisioning, EC P-256 keypairs, and X.509 CSR exchange.
🏗️ Embedded Systems Engineer Intern — Radiogeet · Sep 2025 – Mar 2026
Built an industrial Anti-Collision System for crane operations, deployed at Tata Steel BlueScope. Dual-core ESP32-S3 firmware: one core for real-time UWB proximity ranging, the other for zone-safety logic + an embedded web UI. Used ESP-NOW for low-latency node-to-node links and MODBUS RTU over RS485 to drive an 8-channel industrial relay system. Also interfaced AHT10 / ADS1115 with STM32 and worked with LoRa and Masibus industrial I/O cards.
🔧 R&D Engineer — Ampnics · Mar 2025 – Sep 2025 (Remote)
Contributed to open-source hardware — designed and reviewed PCB schematics & layouts, and supported rapid prototyping through circuit testing, debugging, and iterative design.
