๐Ÿ‘‹ Hi, I'm Gopinath Sekar โ€” Data Engineer

Visitors

Building robust data pipelines, automating everything I reasonably can, and running a fleet of self-hosted services to keep my ops skills sharp. I care about clean engineering, observability, and secure, scalable cloud-native systems.

๐ŸŒฑ Currently exploring: agentic AI workflows & AI-assisted engineering

๐Ÿ› ๏ธ Data Engineering & Cloud

  • Snowflake โ€” procedures, SDKs, perf tuning, Liquibase CI/CD
  • dbt โ€” data modeling & testing on Snowflake
  • AWS โ€” S3, Lambda, SNS, IAM, Secrets Manager, CloudFormation
  • Apache Airflow โ€” ETL orchestration, Dockerized DAGs
  • SQL ยท Python โ€” analytics, data-quality checks, automation
  • GitHub Actions ยท Docker โ€” CI/CD & reproducible environments

๐Ÿ“Š Analytics & Front-End

  • Tableau โ€” trusted-ticket auth, parameter automation
  • Angular ยท Node.js โ€” Tableau embedding, Express APIs, JWT
  • Grafana ยท Graylog โ€” metrics & centralized logging

๐Ÿ  Self-Hosted Homelab

  • ~40 containerized services ยท Docker + Traefik + Authelia SSO
  • Custom observability dashboard (SvelteKit + FastAPI)
  • ZFS / BTRFS ยท scripted auto-updates ยท ops bots

โšก A Few Things About Me

  • ๐Ÿ  I self-host almost everything โ€” if it can run in a container, it probably is.
  • ๐Ÿ“ˆ Obsessed with metrics โ€” if it can be graphed, it's going to Grafana.
  • ๐Ÿง Daily-drive Linux (Ubuntu / Alpine); love tinkering with ZFS & BTRFS.
  • ๐Ÿ” Big on secure pipelines โ€” encryption, secrets management, and IAM done right.
  • ๐ŸŽฎ Occasional detour into gaming & retro consoles.
