Senior React Native & Expo Engineer | SaaS & AI-powered mobile apps for healthcare, fintech & e-commerce
Over the years I've led mobile development for healthcare, fintech, and e-commerce products — including a cross-platform healthcare app serving 6,000+ patients and a fintech investment monitoring app used by 10,000+ users. I care about clean architecture, CI/CD automation (EAS Workflows, GitLab CI), and shipping apps that are secure by default (AES-128, OAuth 2.0).
I've also built and maintained SaaS mobile apps — subscription-based products with user authentication, tiered user roles, and real-time data sync — using backends like Node.js/NestJS, Firebase, and Supabase to handle multi-tenant logic, billing integrations, and account management at scale.
Work Terms
Preferred communication: Slack or your team's tool of choice, with a kickoff call to align on scope before starting. I provide regular progress updates (weekly or per-sprint) and am comfortable with Agile/Scrum workflows (Jira, Confluence).
