Projects Experience

• Async Rust Port Scanner

  Sep, 2025 - Sep, 20252 days

  A simple and fast multithreaded port scanner written in Rust, leveraging Tokio for asynchronous operations and Clap for command-line argument parsing. It efficiently scans a range of TCP ports on a target IP address.

  • Built with Rust, ensuring high performance and memory safety.

  • Uses Tokio's asynchronous runtime to perform concurrent connection attempts, drastically reducing scan time.

  • Features a configurable command-line interface with clap for specifying target IP and custom port ranges.

  • Incorporates a timeout mechanism to prevent the program from hanging on unresponsive ports.

• Rust Distributed Chat Server

  Jun, 2025 - Jul, 20251 month

  A distributed server where users can connect and transmit messages to other users

  • Distributed Systems in Rust

• Rust minigrep

  Jul, 2025 - Jul, 202515 days

  A grep like tool to return lines in a file that contains the given text

  • grep

• Axum RBAC Workspace System

  Jul, 2025 - Aug, 20251 month

  An open-source backend starter kit for building multi-tenant, workspace-oriented applications using Rust and the Axum framework.

  • Built with Rust and Axum for high performance and safety.

  • Features secure user authentication, workspace management, and Role-Based Access Control (RBAC).

  • Includes database migrations, email notifications, and a modular architecture.

• LangGraph Agent for Candidate Information Extraction

  Jul, 2025 - Aug, 20251 month

  A LangGraph-based conversational agent that interacts with users to extract essential candidate information like contact details, job title, and salary expectations.

  • Uses a stateful graph to guide the conversation and ensure all required data is collected.

  • Extracts structured data (JSON) from unstructured, natural language user inputs.

  • Built with Python, LangGraph, and the OpenAI API.
