Experience
Payara Insight - Monitoring Console
A JavaScript and Java integrated monitoring console developed for Payara Server environments that is used to log and track real-time telemetry data for the operational aspects of Payara Server (JVM stats, Memory consumption, CPU behaviour, GC events, etc.), and alert system administrators of critical events (configurable using thresholds) that could be used to isolate specific performance issues on deployed applications.
This application was developed using intensive knowledge of JVM internals (JMX, RMI, GC logs, etc.), and it also used Eclipse MicroProfile API integration for tracking telemetry and health data using application lifecycle event listeners that could be plugged in at deployment time. The console could also monitor external events from surrounding systems using Prometheus/OpenMetrics endpoints and integrate its metrics into a unified dashboard.
The UI of the monitoring console was developed using Angular components.

Facial Recognition and Biometric Tracking Solution
The project aimed to create a system to detect a face in frontal mode in an image obtained from a working camera to track children's attendance at pre-kindergarten and kindergarten schools in multiple regions as part of a social welfare program.
The system uses facial recognition techniques and biometric scans (as a backup) to accurately detect and log the attendance of children 1-3 years old at each school, and then send the data remotely to a centralized server for monitoring and auditing purposes. It was implemented in 2 modules: an application client developed using JavaFX that is installed in each school's and a centralized single instance server application developed using Java EE 7 (deployed on WildFly and GlassFish application servers).

MESH LRCM
I designed and implemented a full software solution to handle RCM analysis and maintenance data monitoring for big companies that operate using mobile and static equipment in their factories and workshops. This solution also handles extensive automated notification alerts for critical events in each piece of equipment maintenance cycle, and provides recommendations to the workshop's operators on how to proceed with these events based on their priority.
The solution has been implemented as a containerized Jakarta EE deployment using Payara Server as its base and using both PrimeFaces and AngularJS to implement the front end. The solution is sold as both an on-premises software unit that can be installed on a customer's infrastructure or as a subscription-based account deployed on a cloud provider (not yet decided when this project was completed), in case the customer didn't want to spend money on localised infrastructure.

AMIGO - Project Monitoring and Budget Control System
Award-winning system in Carbones del Cerrejón Limited that enhances project managers' productivity by allowing them tight control over their project budget and their contractors' activities and expenses, as well as handling payment bills synchronization with the company's ERP and other systems.
The system was implemented as an Oracle Application Server module developed using a combination of the ADF framework and Java EE 5 APIs, along with heavily customized PL/SQL procedures deployed on an Oracle 11g database cluster.
The system also used Python scripts to assist analyst operators in inputting the data needed to track project information (assets, resources, budget data, etc.).
