Featured builds
Four projects that show the range: native iOS, cross-platform analytics, offline-first business software, and production POS. The screenshots do the talking before the stack does.
SetWise 2.0 live on the App Store
A private, local-first iPhone and iPad strength-training app that connects workout planning, set-by-set logging, recovery context, progress analytics, and reports without accounts or subscriptions.
Live on the App Store and Google Play
A public iOS and Android trade journal and analytics app that turns raw trade logs into structured review loops, behavioral insights, and decision-grade reporting.
Live on the App Store and Google Play
A public iOS and Android order tracker and offline-first business management app for small businesses, backed by sync, licensing, analytics, receipts, and admin tooling.
Production POS reliability work
A multi-platform POS platform for restaurants, retail stores, and business operations, built to support real daily store workflows across Android, Windows, and Apple devices.
How I build
I am a mobile app developer who likes the parts of product engineering that get difficult after the screens are designed. My work spans native iOS, Flutter, offline-first tools, fintech, POS, analytics apps, and the backend or admin systems that support them.
01
Designing sync engines, queued updates, local-first persistence, and conflict-safe flows that remain dependable under unstable connectivity.
02
Profiling and fixing memory lag, long-loading screens, frozen UI states, and rendering or state inconsistencies in data-heavy mobile apps.
03
Building SwiftUI products with local persistence, widgets, platform integrations, testing, and App Store delivery as part of the product itself.
04
Shipping mobile apps together with the APIs, admin tooling, payments, release work, and product operations needed around them.
Experience
I work as a Mobile Application Developer at Interflext and build independent products outside work. The common thread is owning practical mobile problems all the way through release.

Lab + side quests
A small set of experiments that add something different to the portfolio: AI-assisted storytelling, gesture recognition, earlier Android work, and a real upstream Flutter contribution.
Research build
A final-year research project combining branching stories, AI generation, voice input, and hand gestures to explore less conventional mobile interaction.
Computer vision side quest
The gesture-recognition work behind TaleCraft, kept as a separate public repository so the MediaPipe and recognition experiments can stand on their own.
Earlier Android build
A firefighter utility app centered on quick access to station information, alerts, events, locations, and team contacts in the field.
Open source
This is deliberately small and manually curated. No runtime GitHub API, no contribution counter, no pretending a tutorial PR is the same thing as engineering work.
Supporting work
Production systems that round out the story without competing with the four featured builds or turning the homepage into a project dump.
