R4 R4ires Discuss a System

Focused systems studio

Reliable integration, AI, and workflow systems for practical automation.

R4ires designs and builds Azure-native platforms that connect finance tools, automate document review, and modernize internal operations without turning the project into a research experiment.

Systems R4ires builds

Engineering for the messy middle between tools, data, people, and decisions.

01

Financial and SaaS integrations

Connect accounting platforms, internal systems, and third-party APIs with durable auth, webhooks, idempotency, and reconciliation.

02

AI document and compliance validation

Turn PDFs, images, rules, prompts, and Azure AI Search-backed context into review workflows with confidence scoring and controlled automation.

03

Azure-native event platforms

Build service boundaries around Azure Functions, Service Bus, Cosmos DB, AI Search, Web Apps, Key Vault, Entra ID, Blob Storage, and observability.

04

Modern internal tools

Replace fragile spreadsheets, manual handoffs, and aging web apps with secure Azure Web Apps that match real operating workflows.

Example systems

Concrete starting points for business automation.

Accounting Integration Hub

Keep customers, invoices, payments, and mappings aligned between internal systems and accounting providers, with traceable syncs your team can trust.

  • Provider-specific adapters
  • Webhook ingestion
  • CDC change tracking
  • Traceable reconciliation

AI Compliance Reviewer

A document validation workflow that reads submitted files, retrieves supporting context through Azure AI Search, applies rules, and routes uncertain results for review.

  • Prompt orchestration
  • AI Search context
  • Per-page analysis
  • Approval confidence scoring

Operations Workflow Platform

A lightweight internal platform for repeatable approvals, notifications, file handling, and operational reporting.

  • Role-aware workflows
  • Audit-friendly activity
  • Focused dashboards

Data Automation Pipeline

A practical pipeline for moving, validating, transforming, and monitoring business data without brittle manual steps.

  • Scheduled processing
  • Error isolation
  • Operational alerts

Senior Software Engineer / Application Developer with deep platform experience.

20+ years Azure systems .NET delivery

Rodrigo brings 20+ years across enterprise software, financial integrations, Azure-native architecture, AI-assisted document workflows, data engineering, and modernization of production systems.

Recent work spans event-driven accounting integrations, OAuth-secured provider adapters, AI document validation, SQL and Cosmos DB data models, and production services built around Azure Functions, Service Bus, Web Apps, Key Vault, Entra ID, and AI Search.

System design

Map the workflow, service boundaries, integration contracts, and data ownership before code becomes expensive.

Buildable delivery

Ship the useful version first, then harden the parts that need scale, traceability, security, and long-term ownership.

Business fit

Translate technical options into a system your team can run, support, and extend without adding unnecessary platform weight.

Start with a system conversation

Bring the workflow problem that quietly burns hours every week.

Whether it is an integration gap, a brittle workflow, or AI validation that needs guardrails, R4ires can shape the first buildable version and turn it into a platform your team can actually operate.
