Selected work
Seven systems, written up honestly. Each one ends with what I’d do differently, because a portfolio that only contains wins isn’t telling you anything you can use.
Healthcare · 2025–2026
12+ interconnected workflows covering patient intake, clinical report processing, billing reconciliation and delivery — built as a personal initiative with no mandate and no budget, adopted as company standard.
60–75% processing time reduction
Healthcare · 2026
A tracking system for an operation where three patient cohorts are always in flight at once, built to survive the messiness of real archive data rather than assume it away.
Zero patient rows stored
ERP · Manufacturing
A ransomware attack wiped a quarter of a client's inventory and billing records. I recovered them from an untouched BI server with MAQL, SQL, and ADVPL.
100% of records recovered
ERP · Quality assurance
A client's lab was certified under ISO and ICONTEC. The ERP's quality module couldn't reproduce its tests, so I mapped the real process and built the gap in ADVPL.
Certified process, not an approximation
ERP · Food manufacturing
Production costs drifted away from what the plant floor knew to be true, with no report to say why. I traced the calculation across 9+ stock tables and 3 modules and rebuilt it from the database up.
Cost-data integrity restored
ERP · Food manufacturing
Six production zones needed what an MES gives, inside a standard ERP scope. I mapped them into four TOTVS Protheus modules, from discovery to integrated testing.
An MES-shaped need, met without an MES
ERP · Plastics manufacturing
A dozen-plus work orders stopped integrating between ERP and MES, and the log said only “field mismatch.” I compared the rejected records against the ones that went through.
Root cause found, fixed the same day
