Message

At Trez, I architect REST endpoints that connect business logic with React and Next.js interfaces. I refactored query patterns and improved data flow, reducing reporting time from 30 minutes to 15–25 seconds.

Previously at SMBS Solutions, I led the refactoring of monolithic backend services into modular NestJS and TypeScript infrastructure. I also developed React applications and REST APIs, and I value test-driven development and rigorous code reviews.
