At Efftech, I rebuilt the Bing reporting import as a submit, poll, and import pipeline, so an hour-long report no longer ties up a worker. I also reduced Google Ads API quota usage by filtering conversions and adding safeguards for rate limits and exhausted quotas.
At Hostnfly, I stopped duplicate bookings from triggering double payments by adding a database rule that made duplicates impossible. I also automated monthly tourist-tax refunds and halved CI/CD time, saving operations 10 hours a week.
At Altagem, I led a programme to address database crashes caused by data that had never been deleted, and built tooling to apply retention rules across clients. I also built and operate Certorama, a SaaS certification-prep platform, solo end to end; I care about data integrity and documenting what I build.
