Subhajit Sarkar
Smart Grid Infrastructure Engineer
Building the cloud-native infrastructure that powers the next generation of smart grids — bridging physical power systems with digital observability, automation, and secure OT/IT convergence.
Status: Available for immediate joining — Open to Middle East & Global roles
ABOUT
I'm a Smart Grid Infrastructure and DevOps Engineer with hands-on experience deploying power grid automation systems using the Linux Foundation Energy (LF Energy) open-source stack at IIT Madras.
My background sits at the intersection of Electrical Engineering, cloud-native infrastructure, and energy domain knowledge — a combination very few engineers in the market possess.
I'm an active member of the LF Energy open-source community and currently building GridOps — a live smart grid observability platform demonstrating IEGC-compliant telemetry, prosumer net metering, microgrid synchronisation, and EMS decision logic.
I'm seeking roles in green energy infrastructure and smart grid operations — particularly in the UAE, Saudi Arabia, and the broader Middle East where energy digitalization is accelerating rapidly.
PROJECTS
GridOps (In Progress) :
Cloud-native smart grid observability platform. Simulates IEGC-compliant Indian grid frequency across four regional zones, prosumer net metering, microgrid synchronisation status, and a rule-based EMS decision engine managing battery dispatch and demand response. Deployed on Azure via Docker Compose. Tech: Smart Grid, IEGC Compliance, EMS Logic, Prometheus, Grafana, MQTT, Docker, Azure, Python Live: grafana.sosmart.space
InfraOps (Planned) :
Smart building digital twin platform simulating lighting systems, occupancy, HVAC, and energy consumption. Applies M.Tech expertise in Illumination Technology — tracking Lighting Power Density (LPD) against ASHRAE 90.1 standards and predicting Lamp Lumen Depreciation for maintenance optimisation. Tech: Digital Twin, Smart Building, Grafana, MQTT, Kubernetes, Python
SecureGridOps (Planned) :
OT security monitoring platform for industrial and utility environments. Simulates SCADA, RTU, and industrial telemetry with IEC 62443-aligned monitoring. Implements Purdue Model network segmentation, security event detection, and OT asset visibility dashboards. Tech: OT Security, IEC 62443, SCADA, Prometheus, Loki, Grafana, Kubernetes
