Wasim Arif

Software engineer across product & design engineering.

I build AI-enabled products end to end—from agent workflows and APIs to accessible interfaces, interaction, and data visualisation. I like the point where a half-formed idea becomes something people can understand, trust, and use.

MockPit documentation showing its runtime provenance model and development tools
tool2026–presentActive

MockPit

Runtime provenance devtools that show whether interface data is live, mocked, derived, hardcoded, or AI-generated before a prototype is treated as production-ready.

Decision
Keep provenance in a framework-neutral TypeScript core, then expose it through React, MSW, custom-element devtools, and a Playwright-aware CLI.
Evidence
Six public npm packages, an MIT-licensed repository, runnable documentation, redaction controls, and automated tests.

Rewriter reading workspace with adapted text and narration controls
product2025–presentActive

Rewriter

An AI-assisted reading workspace that rewrites literature for a chosen reading level and adds natural text-to-speech without losing the flow of the original story.

Decision
Make reading level, source text, and narration part of one calm workflow instead of presenting model controls or exposing a chatbot interface.
Evidence
A working responsive product with text transformation, speech playback, persistent reading context, and recoverable generation states.

Independent research

Do design systems deliver accessibility at scale?

Strong design-system adoption signals were associated with roughly half as many automatically detected accessibility violations. The pre-registered specification then replicated on held-out UK data.

I built the scanner, ETL, confirmatory analysis, frozen artifacts, accessible visualisations, and DuckDB-WASM explorers. The paper reports nulls and detector limitations alongside the result.

Incidence-rate models with agency or organisation controls. Observational evidence; automated checks measure the floor of accessibility, not the whole experience.

Building across product and interface?

I am interested in software engineering roles where product judgement, frontend craft, and the systems underneath the interface all matter.
