Selected Projects
A snapshot of automation and IIoT engagements that demonstrate how I bridge PLC logic, visualization, and cloud analytics.
IIoT Integration
PLC to Cloud MQTT Gateway for Process Control
Problem
A process manufacturer needed remote visibility into a critical production line controlled by a Mitsubishi PLC, but corporate IT had no OT connectivity.
Solution
Designed and deployed an edge gateway that polled the PLC via Modbus, normalized data in Python, and published structured Sparkplug B payloads to AWS IoT using MQTT.
Outcome
Operations gained 24/7 dashboards and automated alerts, reducing on-site checks and enabling rapid response to deviations.
Technologies Used
Mitsubishi PLC, MQTT, Sparkplug B, Python, AWS IoT, Linux edge gateway.
Testimonial
“Fantastic work from Eduardo. His deep understanding of MQTT, industrial protocols, and edge computing was evident. Highly recommend!”
Safety Systems
Mitsubishi Safety PLC Retrofit for Packaging Line
Problem
A packaging OEM required a safety upgrade to meet new regulations across multiple zones without halting production for extended periods.
Solution
Re-engineered the safety architecture using Mitsubishi safety PLCs, redesigned e-stop circuits, and added diagnostic messaging to the main controller and HMI.
Outcome
Achieved compliance, reduced nuisance trips, and enabled maintenance teams to isolate faults faster through detailed alarms.
Technologies Used
Mitsubishi safety PLC, GX Works, safety relays, panel redesign, structured documentation.
Testimonial
“Eduardo’s attention to detail and rigorous testing meant we passed our safety audit the first time. The documentation was impeccable.”
HMI & SCADA Modernization
Ignition & ThingsBoard Upgrade for Multi-Line Plant
Problem
Legacy HMIs offered limited visibility, lacked remote access, and required high effort to update across three production lines.
Solution
Rebuilt the SCADA stack in Ignition and ThingsBoard with reusable templates, multilingual support, and KPI dashboards for leadership.
Outcome
Operators adopted the new interface with minimal training and plant leadership gained a consolidated view of performance and downtime trends.
Technologies Used
Ignition, ThingsBoard, MQTT, PostgreSQL, Allen-Bradley PLC integration, responsive UI design.
Testimonial
“Working across English and Spanish teams, Eduardo kept everyone aligned and delivered a rock-solid SCADA upgrade. The new dashboards finally give us the insights we needed.”
Electrical Design
AutoCAD Control Panel Package for Batch Processing System
Problem
A process manufacturer expanding capacity needed fabrication-ready panel drawings and BOMs that aligned with corporate standards.
Solution
Produced AutoCAD schematics, panel layouts, and wire lists covering power distribution, PLC I/O, and safety circuits, along with procurement-ready BOMs.
Outcome
Panel shop fabricated without rework and maintenance now has accurate as-built documentation for future upgrades.
Technologies Used
AutoCAD Electrical, UL 508A guidelines, Allen-Bradley hardware, documentation templates.
Testimonial
“Every deliverable from Eduardo is production-ready. The new control panels came with immaculate drawings, testing protocols, and training.”
