FigureHowTo was created by Rodney Ossai, an electrical maintenance engineer who spent his days maintaining precision systems at fertilizer plants and gas facilities, and his nights writing code. Every tool on this site exists because a real engineer needed it and couldn't find a clean version of it online.
For years Rodney worked as an electrical maintenance engineer responsible for keeping precision systems running at near-zero downtime across a fertilizer plant, a gas-fired power plant, and a gas processing facility. In those environments, a miscalculation isn't an inconvenience. It's a safety event. Maintaining 99% uptime in systems like those teaches you to demand accuracy from every tool you use.
At night, after shifts at the plant, I coded. Android apps in Kotlin and Java. Web tools in JavaScript and TypeScript. PLC logic for industrial automation. I wasn't a hobbyist, I was solving real problems I'd run into during the day that existing websites handled badly or not at all.
Over time that collection of personal scripts and calculators grew into something too useful to keep private. FigureHowTo is where I made them public built to the same standard I held myself to on the plant floor: correct output, every time, no excuses.
Rodney's engineering career has spanned three of the most demanding industrial environments in existence: a fertilizer production plant, a gas-fired power generation facility, and a gas processing plant. In each, his role was electrical maintenance — keeping precision instrumentation and high-voltage systems operational at 99% uptime. These are not environments that tolerate approximation.
Alongside that career, Rodney developed and published Android applications independently, writing in Kotlin and Java. He also programs PLCs — the industrial controllers at the heart of automated plant systems — which requires the same logic-first, failure-aware thinking that shapes how every tool on this site is built and tested.
Technologies & disciplines
Tools built because someone actually needed them — not to fill a category.
NEC wire sizing, parallel resistance, and other engineering calculations built for accuracy. These came directly from professional field use and are verified against industry standards.
Browse electrical tools →JPG to PDF, image compression, format conversion — tools that run entirely in your browser, process instantly, and never upload your files to a server.
Browse file tools →Word counters, Lorem Ipsum generators, and text utilities built for writers, developers, and designers who need a clean result without a cluttered interface.
Browse text tools →Custom QR codes with logo support, designed to work correctly the first time. No watermarks, no forced downloads, no registration required.
Browse generator tools →We prioritize function. No forced signups, no unnecessary multi-step processes, no bloated interfaces. Every design decision is measured against one question: does this help the user complete their task faster? If not, it doesn't belong on the page.
The majority of our tools run entirely client-side — your files and data never leave your device. For tools that require server processing, we use short retention windows and automatic deletion. We don't sell data, run tracking pixels, or build advertising profiles on our users.
FigureHowTo is built and maintained by a small, independent team, with contributions from subject matter experts in specific fields. When we cover a topic like automotive diagnostics or OBD-II fault codes, a qualified contributor with hands-on experience in that domain writes the content and reviews the tool for technical accuracy. We don't publish outside our collective expertise.
Found a bug or have a tool you wish existed? We read every message and your feedback directly shapes what gets built next. If a tool gave you a wrong answer, we especially want to know.
