WORK HISTORY
Senior Software Engineer @Ketabdaneh
Architected a new backend with microservices architecture, designed RESTful APIs and scaled the platform from 75K to 170K+ users.• Implemented an AI-powered feature as a layer that allows users to ask questions and resolve doubts after completing courses. Leveraged OpenAI API with context of course content. Reduced instructor workload by up to 35%, streamlined support processes.• Implemented event-driven architectures using message brokers such as Kafka and RabbitMQ to improve scalability and decouple services.• Developed background processing systems using workers and Celery for asynchronous task handling.• Worked with AWS services, including Lambda functions, to design scalable cloud-based solutions and serverless workflows.• Built an analytics and KPI dashboard that increased sales by 15–20%.• Integrated AI-assisted development workflows using tools such as Cursor and ChatGPT, enabling faster code generation, automated refactoring, and improved debugging, significantly accelerating delivery cycles that increased team velocity by 100%+.• Reduce downtime period and improved performance by implementing cache layer.• Refactored frontend code, converted to TypeScript modular architecture and style with Tailwind.• Resolved critical UX issues, improving usability, responsive design, and reducing friction along key user flows.• Modernized the deployment pipeline by migrating legacy processes to Docker-based containers, improving environment consistency and simplifying releases across development and production.• Optimized database queries and indexing, improving response times and stability under load.• Applied security best practices and clean architecture principles to deliver maintainable, production‑ready services.
