Projects
Financial systems, automation pipelines, and engineering case studies.
A selection of systems I built around automation, data processing, integrations, and operational workflows. Some projects are private due to company policies, but documented here as high-level case studies.
Focus
Financial systems, accounting automation, process automation, and system integration.
Project Types
Private production systems, internal platforms, and public demo projects.
Approach
Clean architecture, practical engineering, and measurable operational impact.
Production-oriented automation and business systems built for real operational workflows. Source code may be private.
SPED Cross-Check Automation
Fiscal validation workflow for accounting operations
Automation system that parses SPED tax files, collects government fiscal data, cross-validates multiple datasets, and generates Excel reconciliation reports for accounting workflows.
Payroll Accounting Mapper
Automated payroll accounting mapping for multi-client accounting firms
Full-stack web application that reads payroll Excel reports (pay stubs, vacation and 13th salary provisions), resolves accounting mappings by company and cost center, and exports consolidated journal entries formatted for direct import into the accounting system (FPA-ELEVOR).
NFSe XML Automation Pipeline
Government API integration, XML processing, and audit workflows
Automated pipeline for downloading NFSe XML documents through government APIs, organizing files by client and period, extracting invoice data, and generating Excel reports for auditing and reconciliation.
Digital Certificate Compliance Monitoring
Certificate metadata extraction, validation, and compliance visibility
Automation workflow that scans client directories, extracts certificate metadata, validates integrity and passwords, and presents compliance status through internal dashboards.
