Senior Software Engineer and Solutions Architect

Developed a Go command-line application for production-to-staging data imports in N2/N3 support environments. The tool extracts data based on a parent record, maps parent-child dependency trees, and propagates foreign keys to preserve referential integrity.

Built a separate Go automation solution for parsing CSV/XLSX files, creating temporary tables, validating schemas, and loading batch data into homologation and production environments. The solutions reduced manual SQL effort, prevented schema-related errors, and improved processing performance for large datasets.

Developed an automated deployment and backup tool integrated with SVN and Git for release processes requiring multiple documentation artifacts and object backups.

Automated document generation and backup execution for a team of approximately 60 engineers. Reduced deployment preparation from more than four hours per developer to approximately 15 minutes, delivering a reported 93.7% efficiency improvement.

Conducted a financial audit and manual remediation process for hospital insurance claim disallowances, known as glosas, that were causing substantial revenue losses.

Assumed full development ownership of a partially completed .NET web system after the original developer became unavailable. Expanded the ERP-integrated solution with a mobile management dashboard, eliminating unscheduled glosas and supporting product adoption across additional hospital systems.

Implemented a dynamic multilingual architecture to replace an Oracle Native Translator workflow that required separate compiled binaries for each supported language.

Created automated language detection and real-time translation capabilities within the core application architecture. This centralized maintenance, enabled single-source updates, and improved scalability for onboarding new languages.

Investigated a recurring legacy defect that had generated cancelled or phantom inventory requisitions since 2002, causing inventory discrepancies and operational issues across hospital wards.

Performed detailed root-cause analysis, identified a database trigger anomaly, and implemented a definitive production fix. The issue had remained unresolved despite multiple technical teams working on it over seven years.

Led the complete computerization of 33 retail stores with approximately 198 point-of-sale terminals after four prior vendor failures. Delivered integrated credit scoring, SPC legal risk mitigation, collections, loyalty, and financial capabilities using Oracle Forms and Reports.

Also developed a real-time Assembler driver to translate EBCDIC data streams and escape sequences from Bull VIP 7700 terminals into ASCII commands required by a barcode matrix printer. The driver enabled loyalty-card barcode printing without expensive hardware upgrades.

Assumed responsibility during an immediate IT leadership crisis after the IT manager passed away and the sole programmer became unavailable for an extended period.

Established process alignment within six months, removed operational bottlenecks, stabilized systems, and led migration from character-based screens to GUI applications.

Re-engineered the 13th salary calculation routine for an IBM 4341 mainframe payroll system. The existing interpreted and structured COBOL implementation caused severe CPU bottlenecks and multi-hour processing delays.

Rewrote the core calculation in Assembler, optimizing register usage and I/O loops. Reduced execution time from hours to minutes and freed critical batch-processing windows.

Designed and implemented a high-performance cross-reference utility for BLIS/COBOL development on the SISCO MB-8000 minicomputer based on Data General NOVA architecture.

The Assembler utility provided immediate variable mapping and execution-trace reports, replacing slow manual debugging workflows in an environment without a native cross-reference tool.

Developed a low-level Assembler hardware driver for a Burroughs B700 mainframe environment during preparation for an international PepsiCo audit.

Enabled a standalone Unitron microcomputer to emulate a mechanical typewriter-style operator console through a CRT video terminal. The solution improved operator speed, demonstrated technical innovation during the audit, and contributed to securing capital investment.
