A Little Bit About Me

Hello! I'm Divyanshu — a Software Engineer @ Google, dual-degree graduate Computer Science from NIT Hamirpur (BTech CGPA 9.76 · MTech CGPA 9.9, Batch Rank #2).

At Google I work on GDC Air-Gapped infrastructure — building multi-zone Kubernetes DNS mesh, RFC-compliant webhooks, and Prometheus/Grafana SLO pipelines. I also contributed to Gemini's security horizontal (org-wide recognition).

Before Google I was at Microsoft (Azure SQL reliability) and Amazon (AWS Glue migrations). I'm deeply passionate about distributed systems, competitive programming, and mentoring the next generation of engineers.
