Base44 Developer for SaaS Audit

Experienced Base44 developer needed to audit a multi-tenant commission tracking SaaS platform. Responsibilities include verifying data isolation between customer accounts, enforcing role-based access, and ensuring accurate commission calculations and bonus scheme logic. This role is crucial before onboarding our first paying customers. We are looking for an experienced Base44 developer to audit and complete the platform admin of AchieveCommission, a multi-tenant commission tracking SaaS platform built entirely on Base44. The platform is near complete and we are preparing to onboard our first paying customers. Before we do, we need to ensure the platform runs smoothly from an operational perspective — not just technically correct, but genuinely easy to manage day to day. Specifically we need: Security & Data Isolation — each customer's data must be completely invisible to other customers in all scenarios. RLS rules across 17+ entities need verifying and stress testing. Role-Based Access — four customer roles exist (Admin, Finance, Manager, Consultant). Each role must be properly enforced at the data level so customers only ever see what they're supposed to see. Commission & Bonus Calculations — schemes, marginal bands, carry-over, pay-when-paid, split deals, and bonus schemes (monthly/quarterly/annual) must all calculate correctly based on each customer's own configuration. Operational Readiness — we need to be able to onboard new customers quickly, support them if something isn't working, track their payments and subscription status, and manage their accounts from one central admin panel without needing to go into the database. Customer Support Capability — the platform admin must make it easy to see exactly what a customer is experiencing, diagnose issues quickly, and resolve them without disrupting their data. Billing & Account Management — payment tracking, trial expiry, account status, and subscription management must all work reliably so we can keep track of who is paying, when renewals are due, and flag any overdue accounts. This is a critical piece of work before we go live with real customers and we are looking for someone who takes pride in getting the details right.
