At Viqal - AI Operator for hotels, I implemented backend logic for guest segmentation, decreasing the error rate by 15%. I also migrated legacy UI components from Vue.js to React and improved build and testing workflows.
At Koosha Advertising Agency, I designed and implemented a Django REST Framework role-based access control system that handled more than 5K concurrent requests per second. I also shipped an internal URL shortener that saved 30 man-hours per month and refactored SQL queries to reduce response times by 25%.
At Hamrah LMS & Moniaz, I maintained Python microservices and participated in designing the ERD and architecting the exam microservice. I wrote tests with 95%+ coverage and improved high-traffic WordPress endpoint response times from 800ms to 30ms.
