I build mobile & web products that scale and stay resilient offline.
I'm Christian — a Senior Mobile & Web Developer with 5+ years shipping production systems. Offline-first databases, e-commerce checkouts, and custom products like Blurr, Akojo & FuseLite.
I don't just write code — I turn complex concepts into living digital products. Over 5+ years across fintech, ERP, EdTech, social and logistics, my work centers on user-centric design, clean architecture and measurable impact.
A transaction should never fail because the network dropped. I specialize in local relational databases that asynchronously sync with the cloud — and on the web I bring that same precision to e-commerce, doubling conversion rates and read times.
From idea to a product in users' hands.
Four ways I help teams ship — each backed by production systems already running in the wild.
Mobile app development
Premium cross-platform Flutter apps with clean state and 60fps interfaces — shipped to the Play Store.
E-commerce & Shopify
Custom Liquid themes, WooCommerce→Shopify migrations and SEO-tuned storefronts that convert.
SaaS & multi-tenant ERP
Secure Next.js platforms with Prisma/Postgres, AI insights and dynamic billing engines.
Offline-first systems
Local Hive/SQLite databases that sync to Supabase or Firebase the moment the network returns.
Flagship products, end to end.
Live storefronts & brand sites.
The toolkit behind the work.
Mobile Engineering
Premium cross-platform apps in Dart & Flutter — offline-first storage, clean state and custom geolocation components.
Web & Full-Stack
Performant web systems, custom Shopify Liquid, WordPress themes and headless apps tuned for speed and conversion.
Data & DevOps
Relational and realtime backends with reliable sync, plus the tooling to ship and host them confidently.
Principles that keep products alive.
Clean & scalable architecture
Decoupling UI from business logic is non-negotiable. I build for production-scale traffic and distributed teams.
Offline-first resilience
Connectivity should never break a workflow. Local Hive/SQLite stores sync to Supabase or Firebase once back online.
Data-driven UX
Interfaces are art informed by metrics — I optimize layouts to drive sales, read-time and lower friction.
Continuous learning
Tech moves fast and so do I. Currently extending deep JS skills into Vue.js alongside Next.js and PHP.
Numbers that compound.
