Software Engineer at Strativ AB building a SaaS tour booking platform, including payment integrations and an end-to-end Gift Card module.

Bangladesh

Message

At Strativ AB, I build and maintain APIs for a SaaS tour booking platform used across Sweden. I developed its Gift Card module end to end, including gift card purchases, payments, Fortnox accounting integration, and API documentation.

I also implemented a cancellation policy system that records each tour’s rules with the booking, along with a correction flow and audit history. My work has included integrating NeroPay and Zaver, and building hotel imports using Google Places API (New).

Previously, at W3 Engineers Ltd, I rewrote partner cron jobs that had taken over 30 minutes to run so they completed in under 20 seconds. I also worked with BigQuery analytics, ETL pipelines, and reporting dashboards.
