• Experience troubleshooting complex production issues using monitoring tools such as New Relic, Grafana, and others.
• Strong expertise in SQL Server, including performance tuning, indexing strategies, query optimization, and troubleshooting production issues.
• Experience with MongoDB.
• Experienced in implementing asynchronous microservice communication with RabbitMQ.
• Hands-on experience with the Azure cloud platform.
• Strong proficiency in object-oriented programming and SOLID principles.
• Experience integrating AI solutions into customer-facing applications.
• Proficient in leveraging AI to enhance daily engineering work.
• Solid understanding of microservices and micro-frontend concepts.
