The Engineering Philosophy

I build systems where hardware and software exist in perfect symmetry. My work focuses on creating low-latency data pipelines from physical sensors to cloud infrastructures.


With a background in Embedded C and Python, I bridge the gap between "dumb" hardware and "smart" insights, ensuring every packet of data is secure, timestamped, and actionable.
