Web & mobile apps engineered to production standard
One engineer, the whole stack: SaaS platforms with 7 role-based dashboards, a clinical mobile app on Flutter, and an offline-first React Native navigation app that works with zero signal. Design system to database, app store to CI/CD.
Founders who need an MVP built end-to-end (app, backend, deployment) by one accountable senior engineer
Companies with a web product that now needs a serious mobile app (or vice versa)
Products with hard requirements the average dev shop declines: offline-first, real-time, sensor integration
What you get
SaaS web applications
Next.js/React frontends on FastAPI backends: multi-role platforms like my MRO digital twin: 7 role-based dashboards over a 34+ table data model with barcode/QR tracking.
Mobile apps: Flutter & React Native
Cross-platform apps that feel native: Flutter (clinical rehab platform) and React Native/Expo (motorcycle tour companion, launching on Google Play).
Offline-first architecture
Local database as the source of truth, silent cloud sync when connectivity returns, the pattern behind Apex Rider, where every core feature works with no signal and no ride is ever lost.
Real-time product features
Live dashboards, chat, presence, notifications, on WebSocket infrastructure proven at 500+ concurrent sessions.
API design & integrations
REST APIs, third-party integrations (payments, maps, push), and the auth/RBAC layer (JWT, OAuth2) done right the first time.
Apex Rider: offline-first motorcycle tour companion
Problem
Riders tour where there is no signal. Navigation, tracking, and crash detection had to work fully offline, and sync perfectly when the network returns.
Built
React Native (Expo) app with WatermelonDB as the on-device source of truth, MapLibre offline maps with turn-by-turn voice navigation, sensor-based crash detection with SOS, and silent sync to a Supabase/Postgres backend.
Results
100% offline navigation and ride recording
Automatic crash detection + SOS to emergency contacts
Local-first sync: no ride data lost on crashes or dropped signal
Both ship excellent apps; the decision is about your team and integrations. I’ve shipped production apps in both. Rule of thumb: React Native if your team lives in TypeScript/React or you want maximum library reach; Flutter for heavy custom UI and tight rendering control. I’ll recommend one for your case, not my preference.
How long does an MVP take?
A focused MVP (one core flow done properly, deployed, on real infrastructure) typically takes six to ten weeks. The variable is scope discipline, and part of my job is protecting it.
Do you handle app store publishing?
Yes. Store listings, review compliance, signing, crash reporting (Crashlytics), and push notifications (FCM). I’ve taken apps from repo to published listing.
Who maintains it after launch?
Your choice: I hand off with documentation and CI/CD in place, train your team, or stay on retainer. Everything is built so a competent team can take over, no black boxes.
