We have a set of .adv files that contain program or project data, and we need a tool or web application that can convert .adv files back into their original source code or readable format. Your job will be to: Analyze the .adv file structure (we’ll provide sample files). Identify how to decode or extract the data. Build a converter tool (either a desktop app or web-based) that takes .adv files as input and returns the decoded source code / text output. We are open to suggestions for the best technology stack depending on the .adv file structure. Requirements: Strong experience in file parsing / reverse engineering formats Knowledge of Python, Node.js, or similar backend languages Experience working with binary/text file decoding Familiarity with web-based upload & download systems Deliverables: Working script or app that converts .adv → readable source format Documentation on how the conversion logic works. Budget: Open to discussion based on experience and delivery timeline. Timeline: Preferably within 1–2 weeks, depending on complexity.
