Work Experience

Resume/JD Analyzer

RoleMatch AI

Feb 2026 - Present

Built a Django REST Framework backend for resume parsing, JD analysis, and LLM orchestration with JSON schema enforcement, structured output parsing, and RAG pipelines, generating 300+ ATS-optimized resumes. Developed a React dashboard for skill-gap analysis and interview preparation; containerized the Django service with Docker and deployed via GitHub Actions CI/CD, supporting 150+ users with 85% session retention.

AI Coding Platform

FaisCode

Sep 2025 - Present

Created a responsive React application with reusable components and stateful AI chat workflows, backed by a FastAPI service integrating OpenAI APIs for iterative, category-aware code generation; served 200+ users who generated 1,200+ code solutions. Secured the backend with FastAPI, PostgreSQL, and Redis, implementing JWT authentication, a Redis-backed refresh-token store, optimized database indexing, per-user API rate limiting that reduced OpenAI API costs by 35%, and Redis caching for faster responses, sustaining 75% 30-day user retention.

URL Management Platform

ShortLink

Jan 2025 - Jul 2026

Built a full-stack URL shortener using React.js, Django, PostgreSQL, and Tailwind CSS, supporting 200+ shortened URLs with authentication, QR code generation, and a real-time analytics dashboard. Engineered the backend with Redis caching, fixed-window rate limiting, and Celery-based asynchronous click analytics; achieved 89% Pytest coverage across unit and integration tests, including the rate limiter.
