Migrating a Fintech Analytics Stack to Open Source - Kshitish Deshpande - FOSS Meetup Pune

Kshitish Deshpande

Software Engineer @One2N

Migrating a fintech analytics stack off fully managed AWS services can save serious money, but only if you do it without breaking business reporting or slowing teams down. In this FOSS Meetup Pune talk, Kshitish Deshpande (Software Engineer at One2N) walks through how his team helped a cross‑border B2B fintech processing 50–70M USD in daily transactions move from an all‑AWS analytics pipeline (Postgres, DMS, Glue, Athena, QuickSight) to a fully self‑hosted open‑source stack on ClickHouse, Pebble, Prefect, and Apache Superset. You’ll see how they planned the migration, ran both pipelines in parallel, and gave business teams the same dashboards while cutting infra costs dramatically.
