Full stack development and custom integrations for workflows standard platforms cannot solve.

When standard platforms are not enough, Resonant360 designs and builds full stack applications, portals, integrations and workflow tools that connect with Salesforce and your broader business systems.

When full stack makes sense

Some business problems need software, not just configuration.

Most organisations start by configuring existing platforms — Salesforce, marketing tools, project systems. That approach is fast, cost-effective and the right call for most workflows.

But there are situations where a standard platform cannot cleanly solve the problem. A unique customer-facing portal. A workflow that spans multiple systems with no native connector. An internal tool that needs to behave in a specific way your team has designed. A data capture application with specific logic your CRM alone cannot handle.

Resonant360 builds the custom layer when it is genuinely needed — and we connect it to Salesforce, your marketing stack, your data and your operational systems so it does not become an isolated island.

The goal is not complexity for its own sake. It is delivering the right outcome — whether that is a platform configuration, a custom build, or both working together.

Custom web applications

Bespoke web apps built for specific business needs, customer-facing processes or internal workflows standard tools cannot accommodate.

Customer and partner portals

Branded self-service portals for customers, partners or field teams that connect to Salesforce and back-end data sources.

API-driven integrations

Custom integrations between Salesforce, third-party platforms, internal databases and operational systems that do not have a native connector.

Operational dashboards

Custom reporting and operations views that pull from multiple data sources and surface the right information for each team or role.

AI-enabled internal tools

Internal systems that incorporate AI-assisted workflows, automation and data processing to reduce manual effort and improve consistency.

Data capture applications

Purpose-built data capture tools with custom validation logic, workflow triggers and direct integration into Salesforce or downstream systems.

AI-assisted delivery

Faster build. Stronger governance. Human review throughout.

Resonant360 uses AI-assisted delivery methods to accelerate prototyping, development, testing and documentation — without removing the technical review and governance that enterprise-grade builds require.

AI can accelerate the build, but technical review and governance remain essential. Every deployment goes through human-led quality assurance, security review and acceptance testing.

Accelerated prototyping

AI-assisted generation of initial structures, components and scaffolding — reviewed and refined by our development team before any client delivery.

Faster documentation

Technical documentation, API references, deployment notes and user guides generated in parallel with the build, not as an afterthought.

AI-assisted testing

Test script generation, edge case identification and regression testing support — with human QA sign-off before deployment.

Human-governed delivery

Every decision point — architecture, security, data handling, deployment — is reviewed and owned by a senior consultant or developer.

Integration capability

Connect Salesforce, websites, databases and AI workflows.

A custom build is most valuable when it is properly connected. We integrate with the platforms and systems your business already depends on, so nothing becomes a new silo.

Salesforce integration

Custom integrations between your built application and Salesforce — syncing records, triggering workflows, surfacing data and maintaining a single source of truth.

Marketing platform connectors

Integration with marketing automation platforms, email tools, analytics and content systems so campaigns, leads and conversion data flow correctly.

Operational system integration

Connecting to ERP, finance, HR, field service and operational platforms so business-critical data is not trapped in separate systems.

AI and automation workflows

Integration with AI platforms and workflow automation tools to support AI-enabled internal processes, data pipelines and business automations.

Identity and access

Secure authentication and authorisation integrations for customer-facing portals, staff tools and partner applications.
