Full Stack & AI Engineer

|

Building systems that hold up.

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.

Projects

Recoup - AI Revenue Recovery Agent

Node.js · Express · PostgreSQL (Neon) · Gemini API · React + Vite · Resend · Razorpay

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.

Razorpay Buildathon · Track 03

XAI - Explainable AI Health Risk System

React (Vite) + TypeScript · Flask · scikit-learn · SHAP · SQLite

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.

Multi-Role Exam Registration Platform

Next.js · Node.js · Express.js · MySQL · REST APIs · JWT

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.

CollabDoc - Real-Time Collaborative Text Editor

React 19 · Vite · Node.js · Express · WebSockets · Quill.js

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.
