In a decade-long journey into software engineering, I have proven my expertise in building backend services for scale, processing requests in the order of billions per day. I have worked on re-architecting and migrating existing production systems with high availability and reliability. I am well versed in each aspect, from planning, designing, writing code, and setting up infra to owning the service operations. Though not an expert, I have worked on spark, web frontend and DevOps during different phases of my career.
