I have extensive experience building and scaling production-grade APIs using Nest.js and TypeScript, primarily for applications with high reliability and performance requirements. I have been involved from API design to production support, defining clean, modular architectures using Nest.js modules, controllers, services, and dependency injection patterns. I focus on designing RESTful APIs with proper validation, error handling, authentication, and role-based authorization, ensuring consistency and maintainability across services.
On the implementation side, I have built APIs that handle real-world concerns such as pagination, caching, rate limiting, logging, and monitoring. I’ve worked with both SQL and NoSQL databases, optimized queries, and improved API performance by identifying bottlenecks, introducing caching layers, and making services stateless to support horizontal scaling. TypeScript has been central to my work, helping enforce strong typing, shared contracts, and safer refactoring in large codebases.
Beyond development, I actively collaborate with product managers, frontend teams, and QA to understand requirements, translate them into technical designs, and deliver features incrementally. I regularly participate in design discussions, review API contracts with frontend teams, and support releases by handling production issues and post-deployment improvements. My approach emphasizes clear communication, ownership, and building APIs that scale with the business.
