Message

At EastVantage Private Limited, I architect and implement RESTful backend services with FastAPI, Pydantic, and SQLModel. I also develop containerized microservices deployed on Kubernetes.

I integrated Redis caching and Kafka-based messaging at EastVantage, and work on production issue triage using Kibana and Grafana.

Earlier, I developed Python network automation pipelines at ValueLink Technologies Private Limited and Flask APIs at Octal Frames Technology. At Octal Frames, I also implemented React.js features and built OpenCV image-processing pipelines.
