  Cloud & Serverless Architecture

  Design scalable backend systems using Firebase, GCP, AWS, and event-driven architecture. From MVP to production at scale.

  Infrastructure that scales with demand without blowing costs.

  Scale Stack designs and delivers cloud and serverless architecture for Melbourne and Australia-based companies that need infrastructure that grows with demand. We use Firebase, Google Cloud Platform (GCP), and AWS to build event-driven backends that scale from MVP to production without over-provisioning or surprise bills.

  What you get

  • Event-driven and serverless design so you pay for actual usage, not idle capacity.
  • Firebase and Firestore scaling best practices for real-time apps and SaaS.
  • Multi-cloud and hybrid strategies where needed (GCP, AWS, or both).
  • Architecture reviews and migration plans from monoliths or legacy systems.

  Ideal for product teams launching MVPs, scale-ups moving off shared hosting, and enterprises modernising legacy backends. We focus on revenue-critical systems where uptime and cost predictability matter.

  Automation & Workflow Engineering

  Build robust automations that connect CRMs, payments, APIs, and internal tools without breaking. Reliable webhooks, retries, and observability.

  Operations that run without you babysitting them.

  Our automation and workflow engineering service builds reliable connections between your CRMs, payment systems, internal tools, and third-party APIs. We design for failure: idempotency, retries, dead-letter handling, and full observability so operations run without constant oversight.

  What you get

  • Reliable webhook processing and event-driven workflows with retry and backoff.
  • CRM, Stripe, Xero, and custom API integrations that stay in sync.
  • Error handling, logging, and alerting so you see issues before customers do.
  • Documentation and runbooks so your team can maintain and extend automations.

  Perfect for ops teams drowning in manual data entry, finance teams syncing payments and invoices, and product teams connecting SaaS tools. We specialise in automation that doesn’t break when APIs change or volumes spike.

  AI-Powered System Integration

  Integrate AI into real production workflows—not gimmick chatbots. LLM APIs, vector stores, agents, and RAG that ship.

  AI that actually automates business processes.

  We integrate AI into production systems in ways that drive real business outcomes: LLM APIs, vector stores, agents, and retrieval-augmented generation (RAG) that ship and scale. No proof-of-concept chatbots—we focus on AI that automates workflows, augments decisions, and fits your existing stack.

  What you get

  • LLM integration (OpenAI, Anthropic, Google) with safety, cost, and latency in mind.
  • Vector stores and RAG pipelines for search, support, and knowledge bases.
  • Agent and tool-use patterns that plug into your CRM, docs, and APIs.
  • Evaluation, monitoring, and fallbacks so AI failures don’t break customer flows.

  Suited to teams adding AI to support, sales, or internal tools; product teams building AI features; and operations looking to automate document handling or decision support. Melbourne and Australia-based, with experience in regulated and high-stakes environments.

  Real-Time Data Pipelines

  Create reliable pipelines that sync data across platforms and drive analytics, reporting, and operations. No more silos.

  One source of truth, everywhere it's needed.

  Real-time data pipelines from Scale Stack give you a single source of truth across platforms. We build pipelines that sync data from your app, CRM, payments, and ads into warehouses, dashboards, and operational systems—so analytics, reporting, and ops all use the same up-to-date data.

  What you get

  • Streaming and batch pipelines with exactly-once or at-least-once semantics where needed.
  • Sync to BigQuery, Snowflake, or your existing analytics stack.
  • Real-time dashboards and alerts for ops and leadership.
  • Data quality checks, schema evolution, and lineage so you can trust the numbers.

  Built for growth-stage companies that have outgrown spreadsheets, product teams that need reliable analytics, and ops teams that need live visibility. We help Melbourne and Australia businesses break down data silos and ship data-driven decisions.

  SaaS Backend Engineering

  Build scalable infrastructure for SaaS products from MVP to scale. Auth, billing, multi-tenancy, and event-driven design.

  A backend that grows with your product.

  SaaS backend engineering at Scale Stack covers the full stack of what product-led companies need: authentication and authorisation, billing and subscriptions (e.g. Stripe), multi-tenancy, and event-driven design. We build backends that scale from early adopters to enterprise, without rewrites.

  What you get

  • Auth and RBAC that work across web, mobile, and API consumers.
  • Stripe (or other) billing integration with usage metering and invoicing.
  • Multi-tenant data and isolation patterns that scale and stay secure.
  • Event-driven design so new features and integrations don’t require big migrations.

  Ideal for B2B and B2C SaaS teams in Melbourne and Australia building the first production backend, or refactoring for scale. We focus on backends that support fast iteration and predictable scaling.
