Demonstrated ability to build full-stack applications with complex features, including an E-Learning Platform (EduNexus), a real-time communication system (PulseMeet), and a scalable cloud storage platform (CloudVault).
Experience with critical web development aspects such as API integration (Gemini, Razorpay, Stream SDK), authentication (JWT, RBAC), and performance optimization (Redis caching, rate limiting, Zod validation, bcrypt hashing).
Solid understanding of Data Structures & Algorithms, evidenced by a competitive LeetCode rating (1671, top 15.87%).
Project experience showcases practical application of skills in building robust and scalable systems, indicating strong technical potential for a developer role.
However, the 'Lead MERN Engineer' role match is not supported by the stated 'experienceLevel: 0' and lack of professional work experience.

Cultural & Operational Fit

Cultural Fit Analysis

The psychometric test score of 0% raises significant concerns regarding logical reasoning, work attitude, stress handling, and team collaboration. This indicates a critical area requiring further investigation and development. The self-declared soft skills related to teamwork and communication are not validated by the assessment data.
