Osz Gyorgy Csongor
/ Backend Developer
I build modern web applications and AI-powered tools using Next.js, TypeScript, Tailwind CSS, FastAPI, and Node.js, deployed on Vercel. My background in Python, Django, C++, and C\# is reinforced by hands-on projects, including AI code review systems and full-stack social platforms. I have real-world experience with Linux, AWS, SQL databases, and CI/CD workflows, as well as practical exposure to logistics and finance, where I strengthened planning, optimization, and client-facing skills. I focus on delivering high-quality products quickly, learning continuously, and turning ideas into working solutions.
About
I’m a computer engineering graduate and software engineer who learns best by building real products. Most projects in my portfolio started from concrete problems I wanted to solve and were developed into functional, working applications.
My focus is full-stack development, from building clean, responsive user interfaces to designing reliable backend systems and APIs. I work primarily with Python, TypeScript, React, Node.js, Django, and SQL, and I have hands-on experience with cloud tools, CI pipelines, and relational databases.
I believe in practical, iterative development: ship the MVP, validate the logic, improve the system. This mindset shapes how I approach both personal projects and professional work.
Projects
Real problems, real solutions. Every project here was built to learn something new or scratch a personal itch.
CodeReviewAgent
Problem
Developers spend a lot of time performing manual code reviews, which are inconsistent and can miss critical issues.
Solution
Created a full-stack AI-powered code review tool that analyzes code via an API, finds issues, and generates structured reports in real-time.
Outcome
Streamlined code review process for personal projects and demos, enabling faster feedback cycles and consistent review reports. Backend powered by FastAPI + LangGraph, frontend with Next.js.
Social Network
Built a full-stack social media platform supporting user authentication, posts, follows, and personalized feeds.
Stock Trading Web App
Developed a finance web application that allows users to simulate stock trading with real-time price data and portfolio tracking.
Auctions
Created an e-commerce style auction platform with listing creation, bidding logic, comments, and watchlists.
Dispatcher
Shipment and logistics management system for registering, tracking, and organizing transport operations.
Bomberman (C++)
Developed a 2D Bomberman-style game implementing game loops, collision detection, grid logic, and object rendering.
Library Management System
Desktop application for managing books, users, and borrowing workflows using object-oriented design principles.
ZenQuotes
Java-based application consuming an external API to fetch and display motivational quotes, focusing on API integration and object-oriented design.
Single-page web email client implementing asynchronous requests, dynamic UI updates, and mailbox state management.
Infrastructure Cost Estimator
Built a configurable cost estimation tool for infrastructure projects, implementing pricing rules and calculation logic to model real-world budgeting scenarios.
