Computer Scientist · Industrial Maintenance Professional · Builder of Tools
I'm Justin Wagers, a computer scientist and industrial maintenance professional based in Kentucky. I bring a rare dual perspective to every project: a rigorous technical education paired with years of hands-on experience keeping complex industrial systems running. Whether I'm writing Python scripts, deploying web applications, or diagnosing mechanical faults on the shop floor, I approach problems methodically and build solutions that last.
A suite of free, browser-based utilities I built for computer science students and developers. Everything runs locally in your browser, so no data ever leaves your machine.
Convert between binary, octal, decimal, hexadecimal, and any base from 2 to 36, instantly as you type. Handles arbitrarily large integers.
Open Tool →AND, OR, XOR, NOT, and bit shifts with results shown in binary, decimal, and hex, plus a two's complement view at 8, 16, or 32-bit width.
Open Tool →Turn any text, URL, or Wi-Fi string into a scannable QR code and download it as a PNG. Generated entirely offline in your browser.
Open Tool →Compute SHA-256 and other cryptographic digests of any text, useful for checksums, data structures coursework, and security labs.
Open Tool →Base64 and URL encoding/decoding, a JSON validator & pretty-printer, and a text ⇄ ASCII/Unicode code point converter.
Open Tool →Unix timestamp converter, UUID v4 generator, color format converter, and a Big-O & powers-of-two quick reference for exam prep.
Open Tool →Have a project in mind, a question about my work, or just want to connect? Fill out the form and I'll get back to you as soon as possible.
