How does it handle code quality during reviews?

It enforces strict patterns like Zod validation, forbids 'select(*)' anti-patterns in Supabase, and identifies excessive re-renders in React.

Does it provide architectural advice?

Absolutely. It uses a Technical Decision (ADR) format to explain the context, rationale, and trade-offs of different architectural choices.

Which technology stack does this skill specialize in?

This skill is highly optimized for the Maycrest stack: Expo (React Native), Next.js, Supabase, Vercel, and Stripe.

Can this skill help with automated testing?

Yes, it can write comprehensive unit and integration tests using Jest and React Native Testing Library for both frontend components and backend Edge Functions.

Mobile Development

Provides senior-level full-stack guidance, architectural patterns, and rigorous code reviews for Expo and Next.js applications.

This skill acts as a technical lead for the Maycrest stack, specializing in Expo, Next.js, Supabase, and Vercel deployments. It moves beyond simple coding to focus on production-ready architecture, strict TypeScript implementation, and performance optimization. Whether you are refactoring technical debt, implementing complex authentication flows with Stripe, or debugging deep-seated React Native performance issues, this skill ensures your codebase remains scalable, maintainable, and resilient against edge cases.

Key Features

01Strict TypeScript implementation using discriminated unions and generic utilities.

02Runtime data validation using Zod to ensure type safety at trust boundaries.

030 GitHub stars

04Optimized Supabase query design and RLS policy auditing.

05Expert code reviews with specific, actionable feedback on performance and architecture.

06Comprehensive testing suites for React Native and Supabase Edge Functions.

Use Cases

01Debugging intricate issues like Stripe webhook failures or mobile-specific bridge errors.

02Refactoring complex React Native components to eliminate prop drilling and unnecessary re-renders.

03Designing and implementing end-to-end features across Expo frontends and Supabase backends.
