## About the Role

Do you have experience in TypeScript?, * Senior or staff-level experience with React Native and TypeScript

 * Strong backend experience with APIs and relational databases
 * Experience with payments, refunds, booking systems, marketplaces, memberships, or operational and admin tooling
 * The ability to read messy code and make judgment calls quickly
 * Strong written communication: you can explain risks clearly to a non-technical founder or operator
 * Comfort working without perfect specs

Nice to Have

 * Experience with Metabase or analytics cleanup
 * Experience migrating away from NativeBase, NativeWind, or inconsistent styling systems
 * Experience with mobile release pipelines, QA automation, push notifications, and email workflows
 * Prior startup rescue, code audit, or fractional CTO experience

## Description

We are looking for a senior, hands-on engineer to audit and stabilize a consumer mobile product and its internal admin tool, HomeBase. The current system spans React Native, TypeScript, backend APIs, database-driven booking and payment workflows, notifications, and Metabase reporting. This is not a greenfield build. We need someone who can quickly understand an existing codebase, identify architectural and execution risks, separate real problems from noise, and produce a practical recovery plan.

What You'll Do

 * Audit the React Native and TypeScript mobile app and the related HomeBase admin flows
 * Review backend and API structure, database models, and the business logic around bookings, guests, cancellations, refunds, credits, and notifications
 * Identify technical debt, broken workflows, security risks, stale code, and missing tests
 * Review Linear and project artifacts, and compare planned work against actual implementation
 * Produce a prioritized technical recovery plan
 * Ship or supervise one small but meaningful stabilization fix during the engagement
 * Recommend the exact team needed to continue: mobile, backend, data, QA, design, or fractional CTO, * Codebase map: frontend, backend, database, integrations
 * Top 10 technical and product risks
 * What is broken versus merely messy
 * Estimate to stabilize HomeBase
 * Hiring plan for the next 30 to 60 days

Within 2 to 4 weeks:

 * Recovery roadmap
 * Technical debt triage
 * Recommended architecture changes
 * Test and QA priorities
 * One shipped stabilization improvement, or a verified implementation plan, Type: Contract (2 to 4 weeks, option to extend) Location: Remote, US Compensation: Candidate-proposed hourly or weekly rate Eligibility: Eligible to work in the US
