- My name is Sebastian Ramesh, but my commits are more recognizable.
- Pronouns: He / Him / The Debugger
- I’m currently working on architecting a secure, over-the-air update pipeline for a fleet of Edge AI sensors, because reliable deployment is as critical as the algorithm.
- I’m currently learning Zephyr RTOS in depth and exploring RISC-V toolchains to future-proof my hardware abstraction layer thinking.
- I’m looking to collaborate on open-source hardware/software co-design projects, or with startups building the next generation of intelligent, secure IoT devices.
- I’m looking for help with finding exceptional freelance projects that challenge the balance between ultra-low-power design and real-time processing demands.
- Ask me about the journey from a bare-metal register toggle to a stable Linux BSP, or how to debug a timing issue that only happens at -40°C.
- How to reach me:
js.ramesh1990@gmail.com| LinkedIn — Let's talk embedded systems or innovative product ideas. - I love the moment a board powers on for the first time, elegant solutions to memory constraints, and well-documented vendor errata.
- Fun fact: I've written drivers for touchscreens, but I still get a visceral satisfaction from a physical, clicky mechanical keyboard.
I'm an Embedded Software Developer passionate about building efficient, reliable, and scalable software for hardware systems. I specialize in microcontrollers, device drivers, sensor interfacing, embedded C/C++, RTOS, and low-level system programming.
I am constantly exploring modern embedded strategies, IoT architectures, and advanced system design patterns. I enjoy collaborating with people who value innovation, strong technical foundations, and continuous learning.
