Jake Wharton Portfolio
Creator of some of Android's most widely-used open-source libraries (Retrofit, Picasso, ButterKnife, the original AndroidX KTX libraries) — a deliberately bare-bones site for a body of work that speaks for itself.
What makes it work
A breakdown of the choices that make this portfolio stand out.
Library ubiquity as the entire credibility case
Retrofit and Picasso are dependencies in a huge share of production Android apps — when your libraries are already inside the apps a hiring manager's own team maintains, no case study is needed.
Sustained relevance across platform eras
From pre-Material-Design libraries through modern Kotlin Multiplatform work, the work spans over a decade of platform shifts.
A homepage with almost zero design effort, by design
Seven plain text links — blog, presentations, GitHub, résumé — with no visual flourish, consistent with a reputation built entirely on code quality.
What Mobile Developers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
If your open-source work is already inside the apps your target employers maintain, say so plainly.
Longevity across multiple platform eras is a stronger signal than any single popular project.
A near-zero-design homepage is a legitimate choice once your code is the actual proof of skill.
Keep talks and writing aligned to current projects, not just retrospectives.
