Dear Hiring Manager,
Every dashboard a company trusts sits on top of pipelines somebody has to keep honest, and that somebody is usually me. At Orrery Finance I replaced a tangle of fragile overnight jobs with a tested, observable pipeline that analysts stopped worrying about. Building the dependable data foundation that everything else relies on is the work I would bring to your team.
Data engineering is plumbing in the best sense, invisible when it works and painfully obvious when it does not, so I build for the quiet case. I design pipelines that are idempotent and easy to backfill, I bake data quality tests in so bad records are caught before they reach a report, and I add lineage and monitoring so a broken number can be traced in minutes rather than days. Trustworthy tables are the product I am actually shipping.
At Orrery Finance I rebuilt our core reporting pipeline from brittle cron jobs into an orchestrated, tested flow with data quality checks at each stage. Pipeline failures that used to wake someone twice a week dropped to roughly one a quarter, and freshness improved so finance had clean numbers by 7am instead of midday. The quality tests caught a duplicate ingestion bug that had been quietly inflating revenue figures.
Your job description mentions building a modern data platform from a patchwork of legacy jobs, which is precisely the migration I enjoy. I would value a conversation about how I would sequence it without disrupting the reports people depend on. Could we find time to talk?
Yours sincerely, Amara Sissoko
