Backend developer and database administrator for oil & gas industry applications.

• Built and maintained APIs for monitoring thousands of pipelines and processing millions of sensor records daily, focusing on data analysis and presentation for operational insights.
• Led a major backend refactor introducing FastAPI + Pydantic, improving maintainability, boosting documentation quality, and accelerating collaboration with frontend teams.
• Developed backend services to map equipment and sensor data, consolidating previously fragmented internal apps into a unified system.
• Built event-driven services consuming sensor data streams to trigger automated warnings, alarms, and operational controls based on real-time conditions.
• Maintained CI/CD pipelines using GitHub Actions with Docker with on-prem Kubernetes, managing deployments and ensuring system reliability.

Collaborated with a team of freelance engineers under an in-house technical lead to support backend development for a pregnancy tracking mobile app.

• Designed and implemented APIs to provide stage-specific health tips, pregnancy tracking, and clinic referrals based on user profiles.
• Built and optimized a relational database using a Database-First approach, focusing on scalability and flexible schema evolution.
• Developed stored procedures and backend logic to tailor information dynamically to each user’s pregnancy stage and tracked health data.

Worked on multiple client projects as part of the backend team, following Scrum methodology. Took strong initiative on addressing technical debt and improving code quality practices across the company.

• Built backend services for a replacement inspection and inventory platform, focusing on database design and microservice architecture with Azure Functions.
• Delivered APIs and offline-capable features for a fire & security inspection mobile app, essential for facilities where connectivity was unreliable.
• Automated generation of regulatory fire and safety reports, eliminating manual report creation for clients.
• Supported additional projects including a startup social media pilot and a travel CMS, contributing features and bug fixes as required.
• Compiled and drove adoption of a technical debt reduction plan for the inspection app, which reduced bug rates and improved overall maintainability.
• Researched and trialed SonarQube integration into CI/CD pipelines, laying groundwork for company-wide static analysis (though not fully adopted).

Developed applications and device libraries for money management systems, enhancing functionality, third-party integrations, and transaction monitoring.

• Built end-user kiosk applications integrating multiple money devices (acceptors, dispensers, validators) for payments, utilities, and banking transactions — deployed in production, including international installations.
• Developed reusable software interfaces for MEI and CC-Talk devices, enabling both in-house and customer integrations.
• Integrated real-time monitoring services into kiosk apps, providing transaction tracking and auditability.
• Designed and managed supporting web services and databases to ensure transactional integrity and availability.
• Contributed quality improvements while temporarily outsourced at Qualisys for SAP Business One addon development.

Developed applied R&D projects at the intersection of embedded systems, Android applications, and hardware design.

• Built an Android BLE app and UI to control ATV headlights, mounted and tested with embedded hardware systems.
• Designed CAD-based protective enclosures for electronic control devices, ensuring functional durability in mechanical assemblies.
• Developed an aquaponics greenhouse monitoring system, integrating sensors for temperature, pH, dissolved oxygen, humidity, and light, with a backend for real-time data collection.
• Designed both the embedded UI and mobile companion app for a dispensing machine demo, featuring QR-based login and a credit management system backed by a database.
• Produced detailed technical and feasibility reports supporting research and innovation activities.

Assisted the technical manager and planned the project: <em>Feasibility study of photovoltaic cells for airport gas stations electricity supply</em>.

• Implemented dual-axis solar tracking algorithms on microcontroller-based systems.
• Designed and assembled a motor control rig to prototype solar tracker mechanisms.
• Created CAD-based mechanical structures for photovoltaic cells, featuring automatic facet canting.
• Listed as co-inventor on patent <em>System and method for the automatic facet canting of heliostats.</em> (Patent Number: MX2015008322A, December 2016).

Worked on an energy-saving classroom control system project, designed to automate air conditioning and other devices based on schedules.

• Developed an embedded IR control system capable of learning sequences from existing remotes and persisting them with EEPROM memory.
• Built a server-connected Android application for teachers to create and manage classroom schedules for automated device control.

Worked at a solar energy research facility on alternative heliostat control systems.

• Developed a low-cost embedded control system for solar tracking, replacing expensive CompactRIO hardware with Arduino-based solutions at a fraction of the cost.
• Adapted and optimized a solar position algorithm to run efficiently on limited embedded hardware.
• Built graphical interfaces in Processing to control, monitor, and test heliostat mechanisms, including fine-tuning of PID control values.
