Applicant Tracking System

Overview

The project was a full-stack Applicant Tracking System. I worked across application layers to turn a hiring workflow into a structured product that teams could use and extend.

Collaborated across frontend and backend layers.
Organized applicant and hiring data around relational design principles.
Built a foundation for secure, role-aware workflows.

Production

Production work focused on dependable workflows, clear API boundaries, and operational visibility.

Designed and implemented a scalable PostgreSQL database.
Developed RESTful APIs with Node.js.
Added JWT and OAuth authentication with role-based access control.
Documented endpoints with Swagger for team collaboration.
Deployed the application manually on AWS and monitored errors with Sentry.

My role

I contributed as a full-stack intern, moving between product implementation and the technical decisions that connect the interface to the service layer.

Implemented frontend and backend features together.
Translated domain requirements into database and API structures.
Kept authentication, permissions, and documentation aligned.

Experiments

Built and optimized a RAG pipeline for resume parsing.
Connected candidate evaluation to an LLM integration.
Used retrieval and structured data together to support domain-specific decisions.
