- Took over an overnight Pentaho ELT job that failed intermittently and without warning, weighed the replacement options, and rebuilt it on Dagster and Airbyte.
- Moved roughly 10,000 transaction records a day through a Dagster sensor that checks the source cheaply and starts an Airbyte sync only when new rows exist, so the expensive step runs on demand rather than on a fixed schedule.
- Wrote every run to a log table with its outcome and metadata, so a night with no new data and a night where the sync broke stopped looking identical from the outside.
- Stood the platform up on an isolated VM and documented the handover, so the internal team could run it without depending on one person.
- Built the same Indonesian place-name normalizer four ways against an 80,534-entry reference register and compared them on tokens, cost, runtime and traceability before recommending one for production.

- Automated web application deployment across 2 Red Hat Enterprise Linux virtual machines with Ansible over SSH, replacing a manual sequence run by hand on each box.
- Wrote and maintained the Ansible playbooks as the definition of those servers, so a configuration could be rebuilt from its source rather than reconstructed from memory.
