SaaS Platform Web Developer — Melbourne Tech

Launch and scale a production-ready SaaS web platform with a Melbourne developer who already knows how Melbourne product teams ship—fast iterations, clean tenancy, and dashboards investors actually understand.

What You'll Get

• Multi-tenant SaaS foundation - Tenant isolation, role-based access, and org switching built for real B2B usage, not demo-only logins.
• Product UI & admin dashboards - Responsive React/Next interfaces with billing status, usage metrics, and support-friendly admin tools.
• API & integration layer - REST or GraphQL endpoints, webhooks, and third-party hooks (Stripe, Auth0, SendGrid, Slack) wired cleanly.
• Performance & observability baseline - Caching strategy, query profiling, error tracking, and deploy pipelines so you catch issues before customers do.
• Technical handoff pack - Architecture notes, env setup, runbooks, and prioritised backlog for your next sprint.
• Optional on-site workshop - Whiteboard session with your team in Cremorne, Richmond, or South Yarra to lock scope and risks early.

Serving Cremorne & surrounds

Melbourne's digital pocket—between Swan Street and the Yarra, packed with product studios, fintechs, and converted-warehouse SaaS teams—is the primary focus of this gig. I work with founders and CTOs who need shipping velocity without brittle architecture, especially when Melbourne Startup Week, demo days, and end-of-quarter investor updates force hard deadlines. Nearby Richmond and South Yarra product teams are covered too; Collingwood loft offices and CBD satellite teams are in range for hybrid workshops.

• Seed-stage SaaS in Cremorne warehouse lofts needing multi-tenant auth and Stripe billing before a pitch week.
• Scale-up product squads along the Richmond tech corridor refreshing legacy dashboards ahead of conference demos and partner integrations.
• Hybrid delivery: remote-first builds with on-site discovery or sprint reviews across Cremorne, Richmond, and South Yarra (tram/train accessible; after-hours deploy windows available).

My Process

1. Discovery & tenancy map - Clarify users, orgs, billing model, and data boundaries. We document isolation rules before a single screen is built.
2. Architecture & spike - Choose stack boundaries (Next.js/Node/Postgres or your preferred stack), sketch domain events, and prove the riskiest integration in a short spike.
3. Build in vertical slices - Ship thin end-to-end features (auth → core workflow → billing signal) with staging deploys and PR reviews you can click through.
4. Harden & handoff - Load checks, logging, runbooks, and a live walkthrough so your team owns the next release with confidence.

Expert Insights: What Most People Get Wrong

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

• Bolting tenancy on after MVP - Teams ship a single-DB app then add org_id filters later. That leaks data under race conditions and breaks reporting. I enforce tenant context at the request boundary (middleware + row-level policies) and write integration tests that deliberately try cross-tenant reads. Example pattern: resolve tenant from subdomain/JWT once, inject a scoped Prisma/Knex client, and refuse unscoped queries in CI.
• N+1 dashboards that die at 50 tenants - A Melbourne analytics SaaS I audited rendered org metrics with nested loops hitting Postgres 200+ times per page. Fix: materialised usage rollups, cursor pagination, and a single aggregated query with conditional indexes on (tenant_id, created_at). Aim for p95 < 300ms on the home dashboard before launch marketing.
• Webhook handlers that are not idempotent - Stripe or partner events retry; naive handlers double-credit seats. Store event_id with a unique constraint, process inside a transaction, and return 200 only after commit. Add a dead-letter queue and a replay script—your support team will thank you during Melbourne’s busy Q4 renewals.
• Feature flags without kill switches - Shipping dark features is useless if you cannot disable a bad path in production. I wire flags to tenant cohorts plus a global emergency toggle, and document the one-command rollback. Actionable today: put every new write-path behind a flag and log flag evaluation with request_id so you can reconstruct incidents.

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