I'm Benson, an engineer in Edmonton, Canada. I build products, dig into the systems behind them, and follow the evidence when something doesn't add up.
Explore selected workKeep private details out of the prompt.
I build the TypeScript extension and browser workflow for masking names, dates, and identifiers while keeping a document's useful content readable.
Eight fictional examples show private details being masked while useful content stays readable. Static previews show the source before masking. Select an example or open it in PHI Mask to try it yourself.
Follow the claim back to the source.
I build the SDK and the interfaces for checking model citations against source documents and inspecting the supporting passages.
The demonstration follows a citation from a model response to the matching passage in a source document.
Token compression, and why I stopped.
I built DeepClamp in Rust, then moved it to a TypeScript Chrome extension. I decided to shut it down after discovering a savings-accounting flaw in RTK and publishing the reproduction.
As of , RTK's founders are working on the issue.
The archived animation shows repeated context becoming a shorter representation. This is a demonstration, not a production savings measurement.
I also investigate security, performance, and the gap between what a system reports and what it actually does.
Found a >10,000× savings overstatement in a 80,000-star AI tool by tracing its code, token flow and accounting.
Found a regex bug whose fix made affected page loads about 10 seconds faster.
Reported a payment-flow flaw involving a declined upgrade.
2.5B-token prompt exploit bypassed token caps; reported & fixed.
I founded Can I Pay Less, a credit-card rewards comparison business acquired by Ratehub. There, I worked on PostgreSQL/PostGIS indexing and bottlenecks as the site grew to millions of monthly visitors.
At Portia International, I led four developers modernizing a healthcare platform used by thousands of special needs educators. At Adaptive Pulse, I managed a team of seven.
I co-founded Perkify with Alexander Rink, a startup founder and investor. I later co-founded FileLasso with Kristin Condit, a product leader who spent 15 years at Microsoft. Today I work independently on document workflows, citation verification, and privacy.
I'm also an angel investor and a former board director and Finance Committee member of the Queensway Carleton Hospital Foundation.
