Portal17Market-ready in 60 hours to drive adoption
The sprint that reshaped how I think, build, and own products.
Built at Planned, Portal17 began with a simple system failure: an RSVP lost between Slack noise, email overload, and focus-first work habits. It wasn't a user problem, it was a product problem.
In 60 hours, I secretly designed and built a production-ready, cross-platform mobile app, owning the work end to end — from Figma to a shipping Expo build — to rethink event communication around timely reminders, clarity, and product presence.
The result is an extensible codebase now shaping Planned's mobile roadmap, accelerating internal iterations, and enabling faster customer validation, with implementation planned for H2 2026.
SekeiGenerating 3k views and +$8,000 in a month
A conversion-focused landing page for a global design education product.
Built for PG Gonni, this project addressed a recurring question designers face: whether learning to code is worth it — and why most resources fail to answer it clearly.
We designed and shipped a focused landing page Coding for Designers that prioritizes clarity, trust, and conversion. The work spanned positioning, structure, visual foundations, and high-fidelity execution, with a strong emphasis on speed and decision-making.
The result generated ~3,000 page views and $8,000+ in revenue in its first month, and became a core growth surface for the Sekei education brand.
