Rajat Mantri

Backend-leaning software engineer focused on reliable systems, clean service design, and scalable backend architecture. I work across Kotlin, Ktor, Spring Boot, Node.js, React, and PostgreSQL, with a strong competitive programming foundation.

Current Focus

  • SDE Intern at Porter, building workflow orchestration, serviceability, booking APIs, and reliability improvements.
  • CSE undergraduate at MNNIT Allahabad.
  • Active competitive programmer on Codeforces and LeetCode.

About Me

  • I enjoy building backend systems with clear service boundaries, predictable state transitions, and scalable data models.
  • My recent work has centered on orchestration-heavy workflows, internal tooling, dynamic configuration systems, and production debugging.
  • Competitive programming helps me stay sharp on problem solving, data structures, and implementation quality.

Experience Highlights
