Things I've Built

Each of these solved a problem no off-the-shelf tool could handle.

    Real-Time Browser Test Recorder

    Watch it capture every click, type, and navigation — live — as you use the app.

    Writing test scripts manually means mapping DOM selectors, coding every interaction, and constantly updating scripts when the UI changes. This eliminates all of that.

    Using the Chrome DevTools Protocol, the recorder embeds directly into a real browser and captures every user action as a replayable test step in real time — no selectors, no framework. The result was cited in Forrester Research 2022 as an industry-leading capability.

    Real-Time Mobile Test Recorder

    Live screen mirroring with element detection — on real devices.

    Extending real-time recording to mobile is fundamentally harder. Device communication is slower, element hierarchies differ completely, and there's no Chrome DevTools equivalent for mobile.

    This solution extends Appium's device drivers at the protocol level to stream a live screencast alongside real-time element highlighting. Designed and implemented solo. Currently in special-access preview with select enterprise clients.

    Automating the Unautomatable

    Three different legacy apps. Three completely different low-level solutions.

    Enterprise software often predates modern automation APIs. This demo shows three distinct approaches:

    A WinForm app with canvas drawing interactions (custom gesture simulation). A legacy app with zero accessibility support (DLL injection via Microsoft Detour). A WebView-embedded hybrid app (JCEF + Edge WebView2). No off-the-shelf framework touched any of them.

    Industry-First Automation for Schneider Electric

    A challenge the entire industry had tried — and failed — to solve.

    Schneider Electric had a complex industrial application that every automation vendor had attempted and given up on. The root constraint was a fundamental limitation in how the application handled UI state — invisible to standard automation approaches.

    By identifying this constraint and designing a custom automation layer around it, I delivered a working solution. It is now in production.

Built differently.

I started with a publication in Elsevier before writing my first line of production code. That instinct — understand the problem at its root before reaching for a solution — has defined everything since.

At ACCELQ I've worked across the full depth of the stack: Chrome DevTools Protocol, Appium device drivers, DLL injection, WebSocket real-time systems, security hardening, and cross-platform desktop automation. No framework dependency — if I need something, I build it.

I'm looking for Staff Engineer or Engineering Manager roles at remote-first product companies where hard problems are the norm.
