Mobile-first software engineer focused on building, modernizing, and shipping production apps with strong full-stack delivery skills.
I work across Flutter, React Native, native Android, Node.js, APIs, cloud deployments, and product internationalization. My experience includes mobile apps, CRM platforms, internal systems, ERP/API integrations, and multi-language products built for real operations.
Open to remote opportunities.
I build mobile products end to end, from architecture and implementation to release and production support.
My background includes:
- mobile app development and modernization
- legacy app recovery and stalled product rescue
- backend and API integrations
- AWS-backed deployments and operational support
- app internationalization (i18n) and born-global product thinking
I have worked across loyalty platforms, urban mobility, industrial operations, internal software factories, and customer-facing systems, including international remote delivery for a U.S.-based client.
- Mobile app development with Flutter, React Native, and native Android
- App modernization, recovery, and release execution
- Full-stack product delivery with Node.js, SQL, and cloud infrastructure
- REST API and ERP integrations
- Multi-language apps and globally ready product design
- Internal platforms, CRM systems, dashboards, and operational tools
Most production work I contribute to is private because it involves business operations, internal platforms, customer data, credentials, or NDA-restricted codebases.
