Robin Winters — iOS/Full Stack Engineer, 2024–present
I’m an iOS / Full Stack Engineer at ShowFlex, a shipped iPhone fitness product available on the App Store. Since 2024, my work has spanned Swift and SwiftUI engineering, mobile architecture, MapKit event discovery, Firebase-backed data, interaction quality and release execution. Here is how native interaction and structured event data meet in that work.
A map is one part of a discovery flow
Event discovery connects a user's query, active filters, a set of locations and the event currently being inspected. Search results and map markers should refer to the same event identities. A detail sheet should describe the selected event even when the surrounding result order changes.
My work includes MapKit, search and filtering, dynamic geocoding, draggable detail sheets and persistent navigation. The product problem crosses those components: the interface needs clear state transitions as data and selection change. Accessibility, motion and efficient loading are part of the approved engineering scope.
The companion Swift search example demonstrates one general state-management problem: rejecting asynchronous results that belong to an older query. It is a separate educational package, not extracted ShowFlex code and not evidence of the exact implementation shipped in the app.
Event information needs a usable structure
The approved data work includes ingestion pipelines that normalize global event calendars, athlete metadata, registration information and media into structured JSON and Firebase-backed product data. Source information and native presentation meet at that boundary.
A calendar entry, location and registration link are useful only when they can be connected to the event a person is viewing. This explains why the work spans both data handling and the consumer interface. No throughput, latency, accuracy or adoption figures are claimed here.
Public release evidence
The ShowFlex iPhone App Store listing, checked October 2, 2026, identifies ShowFlex Inc. as developer and seller. Version 17.0 describes an interactive IFBB events map and calendar import tools for IFBB Pro and NPC events. That is public evidence for an iPhone product and the listed map/calendar release.
It does not establish an Android release, individual authorship of every feature, a measured business outcome or release of the AI prototypes below. Store metadata can change; the check date matters.
Applied AI remains a distinct work stream
My work also includes prototypes for AI-assisted physique and posing feedback and predictive competition features. These are experimental workflows. They are not described as released product capabilities or validated fitness assessments.
The distinction matters when assessing the portfolio: released iPhone event discovery has public product evidence; AI prototype work has a narrower professional claim and needs additional releasable demonstrations before it can become a detailed implementation case study.
