• Strong hands-on experience with:
• NestJS (modular architecture, dependency injection, guards, interceptors).
• RxJS (observable-based data flow, operators, error handling).
• TypeScript (type-safe backend development).
• SQL (data modeling, complex queries, indexing, performance tuning).
• Proficient in designing scalable APIs and microservices.
• Solid understanding of backend best practices, including error handling, logging, and monitoring.
• Experience integrating with frontend teams using structured design systems and clearly defined contracts.
• Familiar with Git and modern version control workflows (e.g., trunk-based development, feature branching).
  
  

Nice to have

• Experience with Edge computing and serverless functions.
• Exposure to frontend development or working closely with frontend teams using Next.js/React.
• Background in data-intensive applications, performance marketing, or direct-to-consumer products.
