- Architected a modular Yocto-based build environment that streamlined the compilation of diverse middleware modules, reducing build-to-deployment latency and ensuring consistent firmware reliability across Sensormatics gateways.
- Engineered a low-latency IoT communication framework by integrating MQTT and mDNS, eliminating manual network configuration and enabling seamless, 'plug-and-play' device discovery in complex industrial environments.
- Enhanced system uptime and reliability by developing a custom Supervisory task and a high-granularity Logging framework; this facilitated rapid root-cause analysis (RCA) and automated recovery of critical processes in the Linux environment..
- Hardened the system’s security posture by architecting encrypted IPC (Inter-Process Communication) layers using OpenSSL, protecting sensitive data from internal sniffing and ensuring compliance with industrial cybersecurity standards.
- Enhanced system security by implementing encrypted connections between processes using openSSL tools and APIs.
Embedded Software Developer
Alstom Transport
Bangalore
07.2016 - 05.2020
- Crafted various C modules for embedded Linux environments, incorporating diverse requirements and functionalities into ALSTOM's generic Middleware name OPERA. This Middleware acts as an interface for ARM and Intel-based processors, utilizing advanced IPC like shared memory, Message queues, Sockets and Multithreading techniques.
- Strengthened cyber security features in OPERA Middleware by implementing cryptographic concepts, employing Linux hardening techniques, configuring iptables-filter (Firewall), and harnessing network security protocols such as SSH, TLS, SHA, SFTP, and HTTPS.
- Proficiently debugged code by analyzing core dumps, addressing memory leaks, and strategically placing breakpoints using tools like Strace, valgrind etc.
- Developed C-based test applications to validate APIs, and automated test cases through Python scripting.
- Successfully interfaced peripherals like EEPROM and RTC using I2C and SPI protocols, along with creating an I2C Device driver to read EEPROM for ARM-based boards.
