Shipped a production React.js site with component-driven architecture and Vercel deployment. Worked through Agile sprints and code reviews while translating technical decisions for non-technical stakeholders.
I'm Gnaneshwaran K, a Full Stack Developer focused on building modern web applications, scalable backend systems, RESTful APIs, real-time applications, and cloud-based solutions.
I enjoy working across the entire stack, from designing responsive, component-driven interfaces to building backend architectures, relational database systems, authentication, authorization, real-time communication, and cloud deployments.
I'm currently expanding my cloud expertise through the AWS Solutions Architect - Associate (SAA) course.

Complexity Analysis
Autonomous payment-recovery agent with human-in-the-loop guardrails.
Rule tables catch known Razorpay failures instantly; Gemini reasons about unknown causes inside a fixed action set.
Retry caps, cooldowns, escalation, promise-to-pay tracking, and outbound approvals remain deterministic and auditable.
Predicts diabetes and blood-pressure risk with interpretable Logistic Regression and depth-limited Decision Tree models.
SHAP contributions become human-readable explanations and feature-driven recommendations.
Includes a Random Forest research baseline and feedback module for trust and usefulness analysis.
Concurrent, multi-tiered REST API supporting simultaneous student and admin workflows.
Normalized MySQL schema with foreign key constraints.
JWT-based RBAC with middleware-driven authorization.
12 endpoints tested in Postman; resolved async race conditions.
Google Docs-style editor using a custom Operational Transformation algorithm.
WebSocket server synchronizing cursors, presence, and document state.
Autosave and 50-edit revision history; deployed on Vercel and Railway.
