SaaS Platform Web Developer Serving Cremorne & Melbourne CBD

Get a production-ready SaaS web platform built by a Melbourne developer who already works with Cremorne product teams and Collins Street fintechs—not a generic offshore template.

What You'll Get

• Multi-tenant SaaS architecture - Tenant isolation, role-based access, and schema strategy chosen for your growth stage so you do not rebuild at Series A.
• Subscription & billing integration - Stripe (or equivalent) checkout, webhooks, plan upgrades, dunning hooks, and audit-friendly invoice events.
• Admin & customer dashboards - Fast React/Next.js UI with server components, protected routes, and usage metrics your ops team will actually open.
• API design & documentation - Versioned REST or tRPC endpoints, rate limits, and OpenAPI notes for internal and partner consumers.
• Performance & observability baseline - Query budgets, caching layers, structured logs, and error tracking wired before launch week.
• Handoff package - Repo structure, env docs, runbooks, and a short loom-style walkthrough so your next hire is not guessing.

Serving Cremorne & surrounds

Cremorne’s warehouse-converted studios and co-working floors sit next to Richmond’s product agencies and the Collins Street / Melbourne CBD fintech pocket—exactly where SaaS founders need a developer who can workshop in person then ship async. I plan sprints around Melbourne’s real calendar: Melbourne Knowledge Week demos, end-of-financial-year billing rushes, and the post-holiday January rebuild window when product roadmaps get rewritten. Nearby South Yarra and Fitzroy teams are covered for stand-ups and whiteboards without burning half a day in traffic.

• Cremorne & Richmond SaaS startups needing multi-tenant MVPs before investor demo days
• Collins Street corridor teams shipping internal tools or customer portals ahead of conference and Knowledge Week showcases
• On-site discovery in Cremorne warehouse offices; remote pair sessions preferred for deep coding, with South Yarra / CBD catch-ups when stakeholders need a screen share in the same room

My Process

1. Step 1: Product & tenancy discovery - Map users, roles, billing model, and data boundaries. We decide shared-db vs schema-per-tenant early so you avoid a costly rewrite.
2. Step 2: Architecture spike & backlog cut - Thin vertical slice (auth → core workflow → webhook) with acceptance criteria, non-functional targets, and a realistic milestone plan.
3. Step 3: Build in vertical increments - Feature flags, PR reviews, staging deploys, and weekly demos timed to your Melbourne stakeholders (AEST).
4. Step 4: Harden & handoff - Load checks on hot paths, secrets rotation notes, runbooks, and support options via 0421498927 or fixwebnode.com.au/contact-support.

Expert Insights: What Most People Get Wrong

Based on 12+ years of shipping multi-tenant products, here are the critical mistakes I see clients make—and how I fix them:

• Soft multi-tenancy that leaks under pressure - Filtering by tenant_id only in the controller is not isolation. I enforce tenant context at the ORM/query layer (e.g. Postgres Row Level Security or a mandatory tenant scope on every repository method) and add integration tests that attempt cross-tenant reads. A Cremorne marketplace client once “secured” tenancy in middleware alone; one missed join exposed another org’s invoices. We added RLS policies plus a CI check that fails any raw query without tenant predicates.
• Billing webhooks treated as fire-and-forget - Stripe (and peers) retry; your handler must be idempotent. I store event IDs, process with a state machine (received → applied → failed), and never trust client-side “payment success” alone. Pattern: verify signature → upsert by event.id → apply side effects in a transaction → return 200 only after commit.
• N+1 dashboards that die at 50 tenants - Pretty React tables that hydrate full graphs per row collapse once real usage hits. I push aggregates to SQL (window functions / materialized views), paginate cursor-style, and cache per-tenant summary keys with short TTLs. Rule of thumb: if the network waterfall shows more than ~8 related fetches for one screen, we redesign the query boundary before launch.
• Microservices too early, monolith never designed - Splitting auth, billing, and core product into three repos before product-market fit multiplies deploy pain without buying scale. I ship a modular monolith (clear domain folders, internal ports, single deployable) and extract only when a bounded context has independent scale or team ownership. Actionable now: draw your domain map; if two modules always deploy together and share transactions, keep them co-located.

When you hire me, you get all this expertise applied directly to YOUR project—saving you time, money, and headaches.
