Experience

3D Plane Reconstruction

An application for automatic point cloud processing and extracting 3D planes that satisfy the given constraints. I modified the RANSAC algorithm for fast plane detection in large, noisy point clouds. I developed this project in C++ using Point Cloud Library.

Trading Software

Software for backtesting trading strategies and performing automatic trades on several trading platforms. I spent a lot of time testing and optimizing this app because each second has a big impact on the performance.

Booking Scraper

A Python-based application for scraping hotel availability data from different booking websites and creating reports based on that data. I developed a scraper that tracked the real-time data as well as collected and analyzed the historical data.

Social Media Extension

A browser extension for automatic posting and messaging on various social media platforms. This extension allows the user to publish the same post on different social platforms at once. Supported platforms include Facebook, Instagram, and Twitter.

Interpreter

Created an interpreter for a simple programming language that supports arithmetic and logic operators, variables, conditional branching, and loops. I developed this app as a part of my coursework. It takes a program file as input and interprets it line by line. The app indicated all of the syntax, semantic, and logical errors to the user.
