Antoine van der Lee Portfolio
Lead iOS engineer turned founder — his SwiftLee blog reaches tens of thousands of weekly subscribers, an audience he converted directly into RocketSim, a paid Xcode Simulator tool now used by 80,000+ developers.
What makes it work
A breakdown of the choices that make this portfolio stand out.
A newsletter used to validate a product before committing to it
A large weekly subscriber base gave him a pre-qualified audience of exactly the iOS developers RocketSim was built for.
The content-to-founder transition documented, not hidden
Both identities — iOS blogger and tool founder — coexist on the same site, giving other engineers a real case study of the mechanism.
A specific usage number as the product's credibility anchor
Used by 80,000+ developers gives concrete, verifiable scale — the same instinct as quoting GitHub stars, applied to a commercial product.
What Mobile Developers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
If you write consistently for a technical community, consider what tool that same audience would pay for.
Don't hide a pivot from content-creator to founder — show the mechanism as a case study.
State your product's real usage number plainly once you have one worth sharing.
A newsletter is a durable, algorithm-independent audience channel — build one early.
