Full-Stack Next.js & Supabase Developer for ERP SaaS

@Microlent

The biggest challenge here is not adding modules, it’s ensuring your current system scales without performance bottlenecks or data inconsistencies, especially with Supabase RLS. You already have a strong foundation. Now the focus is stabilizing queries, refining UX, and preparing the system for SaaS-level growth. We’ve worked on SaaS platforms involving finance, dashboards, and role-based systems where performance, data integrity, and scalability were critical. Approach Audit and optimize Supabase queries, RLS policies, and indexing Clean up TypeScript issues and standardize data flow across modules Improve mobile responsiveness, loading states, and error handling Most teams rush into new features. We focus on stabilizing the core so future modules don’t introduce technical debt. Quick question Do you have query logs or performance metrics available from Supabase to identify current bottlenecks? We can quickly stabilize your system and support the roadmap toward a scalable SaaS product. Best, Jenifer

Hello, I can help you stabilize and scale Vertex Suite by fixing existing issues, improving performance, and ensuring the codebase is production-ready for further SaaS expansion. I have recently worked on similar complex web applications involving performance optimization, database query fixes, and UI/UX improvements in scalable systems. What I will focus on (Phase A): • Fix TypeScript errors and interface mismatches • Optimize Supabase queries and improve RLS performance • Replace legacy user_id logic with business_id properly • Improve mobile responsiveness and layout stability • Add loading skeletons and global error handling • Audit and optimize slow queries with proper indexing I work with clean, scalable architecture and ensure the system remains maintainable for future module expansion. Ready to start immediately.

The main challenge here isn't building from scratch - it's understanding your existing Vertex Suite architecture and extending it without breaking production workflows your SMB clients rely on. I've built 28 React/Next. js projects in the last 2 years, including SaaS platforms with amplu state management and real-time data sync. My approach: audit your current Next. js + Supabase setup first, identify improvement opportunities (especially for Indian network conditions), then implement new features with proper testing before deployment. Since you're already live with users. I'll focus on zero-downtime changes and backward compatibility. I work extremely fast with modern tooling - typical feature additions take hours, not days.

Hi I have carefully reviewed the Vertex Suite project brief. Your focus on a custom Vanilla CSS design system and strict Supabase RLS policies perfectly aligns with my development philosophy of building lean, high-performance applications. I am ready to tackle the Phase A stabilization immediately, specifically: TypeScript & Query Migration: Resolving interface mismatches and shifting to business_id logic for cleaner multi-tenancy. Performance Tuning: Using EXPLAIN ANALYZE to optimize RLS and indexing for high-load scenarios. UI/UX Polish: Implementing custom CSS layouts for mobile responsiveness and global error handling.
