Example Achievement Log for a Business Intelligence Analyst

A year in the life of a Business Intelligence Analyst's log

• Feb - task: Started auditing the legacy SFDC-to-Tableau pipeline for Q4 reconciliation. Found 340 duplicate account records in the sync logic that was causing 12% variance in churn reporting.
• Mar - achievement: Rebuilt customer health dashboard in Tableau. Cut refresh time from 47 minutes to 8 minutes by consolidating six separate queries into a single materialized view in Snowflake.
• Apr - feedback: Valerie from Finance flagged inconsistent cohort definitions in the retention model. Took her feedback seriously and rewrote the SQL; she said the new logic was 'exactly what we needed'.
• Apr - task: Led migration of customer lifecycle events from Mixpanel to dbt-transformed tables. Initial load missed 8% of events due to timestamp UTC misalignment; had to rebuild three transforms.
• Jun - achievement: Published the first single-source-of-truth activation report for the campaigns team, pulling from our new event warehouse. Coverage went from siloed spreadsheets to real-time metrics.
• Jul - feedback: Marcus in Operations emailed to say the new ARR forecast dashboard saved them six hours of manual spreadsheet work each month. Asked me to present it to his full team.
• Jul - achievement: Developed anomaly detection alerts in dbt tests to flag when daily active users drop below the 90-day rolling average by more than 15%. Caught a data pipeline breakage two hours before the ops team noticed.
• Sep - task: Took over ownership of the monthly board deck metrics from the departing analyst. Rewrote three of the seven charts to use the event warehouse instead of the old SFDC extracts.
• Oct - achievement: Validated the Mixpanel migration completeness. Compared event counts row by row across 14 event types and signed off that parity was within acceptable 2% tolerance as of Sept 30.
• Oct - task: Built a new LTV cohort analysis tool for product to test pricing tiers. Learned Streamlit for the first time and deployed it to a shared app server in three days.
• Dec - feedback: Angela, our VP of Operations, asked me in the all-hands what our biggest data risk was. I said the legacy Mixpanel events were still running in parallel and cost us $8k monthly. She prioritized the full cutover.

What makes a strong entry

How this becomes your review in November

I completed a major data migration from Mixpanel to our new dbt-transformed event warehouse, validating parity across 14 event types and achieving acceptable tolerances by October. While the initial migration missed 8% of events due to timestamp handling, I rebuilt the logic and signed off on the cutover, which Angela later prioritized to eliminate ongoing duplicate infrastructure costs of $8k monthly. I also rebuilt the customer health dashboard to cut refresh time from 47 minutes to 8 minutes by consolidating queries into a materialized view, work that Marcus said saved his Operations team six hours monthly and earned me an invitation to present to his full team.
