Hi there, Revisaré tu SaaS nutricional con React + TypeScript + Supabase y entregaré el informe de auditoría priorizado, las correcciones de RLS y Edge Functions, y el checklist de producción con el pipeline CI/CD en verde. En un SaaS clínico similar con Supabase, encontré políticas RLS que filtraban en frontend pero no en la base real. Lo corregí antes de que llegara a producción. Questions: 1) El flujo de Culqi ya procesa webhooks en Edge Functions, o la activación de suscripción se maneja desde el frontend? 2) Tienen tests e2e escritos que necesiten repararse, o los creo desde cero? Compartan acceso al repo y haré la auditoría de arquitectura como primer entregable. Kamran

Hi, your "Full-Stack Senior para SaaS Nutricional" project is right in my wheelhouse. I develop modern JavaScript apps end to end — React/Vue/Next on the front and Node/Express on the back, in TypeScript where it helps. Working with javascript, python, node.js, postgresql, angularjs, full stack development, saas, supabase, I focus on responsive, fast UIs, clean component structure, and reliable APIs — no page-builder shortcuts. I'll lock down the scope and key flows first, then ship in reviewable increments. Can we hop on a quick chat to align on your requirements? ⭐ 5.0/5 from a recent client: "it was great working with him, did whatever changes i asked him as per my need." Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hi You’re looking for a hands-on senior full-stack to audit and finalize your clinical nutrition SaaS for a solid, secure production launch—tighten code quality, validate what’s built, close gaps, and ensure reliable CI/CD, observability, and security. I’m a results-driven developer with React/TypeScript and Supabase, delivering production-ready outcomes. I translate complex stacks into clear, actionable improvements: architecture reviews, debt reduction, and concrete next steps that align with security, performance, and maintainability. I turn audit findings into prioritized PRs and a finished runbook to keep the system solid after launch. For your project I’d structure the work in concrete phases: 1) frontend, Edge Functions, RLS policies, and authentication/roles audit; 2) migrations, indices, and query performance verification; 3) end-to-end flow for Culqi billing, webhooks, and access control; 4) observability, jobs/worker reliability, and bundle/load performance; 5) production-ready closure with a green CI/CD pipeline and a readable backlog with blockers resolved. The outcome is a prioritized readiness list, implemented fixes via PRs with notes, and a turnkey production checklist with brief remaining guidance. I can deliver concise audit findings, implemented changes through PRs, and brief documentation outlining remaining work and recommendations for ongoing reliability. Best, Justin

@mayankinnovative

As an experienced full-stack developer, I bring with me a multitude of skills and extensive knowledge of the key technologies involved in your project. I have a strong proficiency in both React and TypeScript, which are vital for your frontend. For your backend needs, I am well-versed in working with Supabase and PostgreSQL, including implementing RLS policies to ensure secure authorization and separation of roles between admin and client. Moreover, my expertise extends to encompass areas that align perfectly with your requirements such as CI/CD, serverless architecture utilising Edge Functions (in this case Deno), and deployment using Vercel. I believe my deep understanding of these tech stacks will allow me to carry out a comprehensive code audit and validation of existing functionalities. In terms of past projects, I’ve had the pleasure of working on several SaaS applications like yours where a meticulous examination for security vulnerabilities, efficiency improvement, and reliable performance was required. Additionally, my process leans towards establishing long-term stability by conducting extensive checks to detect any inconsistencies between code repositories and live databases. I also ensure end-to-end functionality, thoroughly validating payment flows from checkout to webhook. My system approach guarantees an organized completion of deliverables: an insightful audit report on code quality and strategy to address the findings; progression towards readability;

@jcrbahia

Trabajo habitualmente con Supabase, RLS y Edge Functions en Deno; el punto que más me interesa del alcance es el drift entre migraciones y la base real, y el estado del sistema de colas/worker en segundo plano — ahí suele estar el riesgo real antes de un lanzamiento. - Auditoría de políticas RLS por tabla y rol (admin/cliente), probando casos de acceso cruzado, y revisión de las Edge Functions (validación de inputs, gestión de secretos, límites de tasa). - Verificación del flujo Culqi completo (checkout, webhook, activación/expiración) con pruebas en sandbox antes de tocar producción, y montaje de Sentry para monitoreo real de errores. - ¿El worker de jobs en segundo plano está corriendo hoy en producción o quedó como prototipo? Eso define si lo estabilizo o lo documento como pendiente priorizado en el informe. Puedo entregar el informe de auditoría, las PRs críticas y el pipeline de CI/CD en verde en 7 días. Toma esta cifra como una referencia inicial y orientativa para el alcance descrito, no como precio definitivo; confirmaremos el número exacto en cuanto concretemos los detalles que aún faltan. Si te parece bien, hacemos una llamada breve de 15 minutos aquí en Freelancer para repasar estos puntos — con gusto comparto ejemplos relevantes de mi perfil.

Puedo auditar y fortalecer tu SaaS nutricional, revisando frontend, backend y arquitectura para dejarlo listo para producción con estándares de seguridad y rendimiento. Tengo experiencia con React+TS, Supabase (RLS/Edge Functions), CI/CD en Vercel y flujos de pago. Si quieres, puedo detallar cómo realizo una auditoría Supabase RLS o cómo estructuro un hardening SaaS clínico para entornos sensibles. Mi enfoque: • Auditoría completa del código (frontend + Edge Functions). • Validación de RLS, roles, autenticación y manejo de secretos. • Revisión de migraciones, índices y consultas para escalar. • Validación del flujo Culqi: checkout, webhook, activación/expiración. • Observabilidad: Sentry, logs y jobs en segundo plano. • Optimización de bundle, navegación y CI/CD (lint, typecheck, tests, e2e). • Checklist de producción y PRs claros con correcciones. He trabajado en SaaS médicos y de bienestar con Supabase, reforzando seguridad y rendimiento antes del lanzamiento. Puedo entregar por hitos o por hora según prefieras.

@alizain721

Lo más habitual en este tipo de SaaS no es que “no funcione en la demo”, sino que haya pequeñas brechas (drift de migraciones, RLS permisivo, validaciones ausentes en Edge Functions, webhooks de facturación sin idempotencia) que explotan al subir usuarios reales o al pasar a producción. Mi propuesta práctica: empezar con una auditoría rápida (revisión del repo, schema y políticas RLS, tests básicos de flujo de facturación), priorizar hallazgos críticos y entregar PRs para los bloqueos: harden RLS, input validation en Edge (Zod), manejo seguro de secretos, pruebas de webhook Culqi, e2e para auth y suscripción, y pipeline CI verde. Stack/implementación: mantengo React+TS+Vite+Tailwind y Supabase (migrations via supabase CLI en GH Actions). Añadir Sentry para observabilidad, Zod para validación, y asegurar migraciones en CI. Recomiendo revisar índices con EXPLAIN y validar RLS con pruebas automáticas. Mantenimiento/flexibilidad: trabajo por hitos (Audit 10–15h; Correcciones críticas 20–35h; CI/monitoring/docs 10–20h). Estimo 40–70 horas a 11.5 USD/h y entrego PRs y checklist “listo para producción”. Proyectos similares: Program Pro (rol: full‑stack lead, arquitectura SaaS, Postgres, AI; entregué generación de planes y reporting); Tax Plan Hero (rol: full‑stack, flujo de suscripción y facturación, PostgreSQL). ¿Comenzamos con una auditoría de 7 días para entregar el informe priorizado y PRs iniciales —puedo recibir acceso de solo lectura al repo y al proyecto Supabase tras NDA?

@jazz78p

Hola, soy Leo Sarmiento, desarrollador full-stack senior con React, TypeScript y Supabase con más de 10 años de experiencia en auditoría y lanzamiento de SaaS en producción. El verdadero desafío de esta revisión no es listar problemas de código, sino validar que las políticas RLS de Supabase efectivamente aíslen los datos por clínica y que las Edge Functions manejen correctamente la idempotencia de los webhooks de Culqi, evitando que un pago fallido o un reintento duplique activaciones de suscripción; además, la auditoría debe priorizar la consistencia entre el esquema de la base de datos y las migraciones del repositorio para que el despliegue sea confiable.

@vladang

Ya tienen un producto funcionando, así que el reto no es desarrollar más funcionalidades sin criterio, sino comprobar que todo aguante un entorno de producción real. Empezaría revisando el estado del repositorio y las migraciones para detectar cualquier diferencia con la base de datos, después validaría las políticas RLS, las Edge Functions y el flujo de autenticación para asegurar que no existan accesos indebidos. A continuación revisaría el ciclo completo de suscripciones con Culqi, los jobs en segundo plano y el pipeline de CI/CD hasta dejar builds y pruebas consistentes. También dedicaría tiempo a rendimiento, desde consultas e índices hasta el tamaño del bundle y la navegación. Hace poco trabajé en un SaaS con React, TypeScript y PostgreSQL donde el objetivo fue precisamente cerrar los últimos riesgos antes del lanzamiento, documentando cada hallazgo y entregando las correcciones mediante PRs claros. Las Edge Functions ya cuentan con pruebas automatizadas o habría que incorporarlas durante la auditoría? Estoy listo para empezar.
