Allan Galarza

Early-stage startup building data processing and reporting platforms for financial and investment workflows.

• Integrated LLM-assisted components into data processing pipelines to transform, validate, and enrich structured datasets.
• Designed end-to-end data processing workflows combining deterministic pipelines with LLM-assisted components for transforming and validating structured financial data.
• Defined architectural patterns for integrating LLM-based systems into production, including prompt design, validation layers, and error handling.
• Provided technical guidance and architectural feedback to engineers during design and implementation.

Startup developing data processing and reporting workflows for financial and investment-related domains.

• Reduced report generation time by 60% through backend optimizations and data aggregation improvements.
• Designed and implemented APIs for workflow orchestration and data analysis, leveraging containerized services on GCP with Windmill for scalable task execution.
• Improved developer onboarding and deployment speed by building a modular architecture that supports scripts in multiple languages with automatic dependency management.

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.
