Software engineer with 7+ years of experience focused on backend systems and distributed application design, primarily in the .NET ecosystem.

I work on building software that prioritises:

• predictable behaviour under load
• maintainable architecture over time
• clear separation of concerns
• alignment between business rules and implementation

Most of my experience comes from designing and delivering systems in production environments with real operational constraints.

Backend & Architecture

• C# · .NET Core · ASP.NET Core · .NET Framework
• REST APIs · Microservices · Event-driven systems
• Clean Architecture · Domain-oriented design

Frontend (supporting role)

• Angular · Next.js · JavaScript · HTML · CSS

• Azure (App Services, CI/CD pipelines)
• RabbitMQ (message-based communication)
• Elasticsearch (search and indexing systems)
• SQL Server · PostgreSQL · MySQL
• Docker (in progress)
• Visual Studio · Postman · PowerShell

System designed for secure processing and validation of physical lottery tickets using OCR and centralised data storage.

Responsibilities

• System architecture and full implementation lifecycle
• API design and backend services in .NET
• SQL Server schema design with auditability constraints
• Desktop + PDA applications for operational workflows
• Message-based processing for reliability and decoupling

Outcome

• Reduced processing time by ~80%
• Introduced traceable digital workflow for regulated operations
• Deployed in production across a national-scale environment

Enterprise module set for managing PPE distribution and compliance tracking.

Responsibilities

• Designed end-to-end workflow architecture
• Implemented full request/approval/delivery lifecycle
• Built reporting and traceability components
• Integrated business rules into backend services

Outcome

• Standardised PPE operational workflow across the organisation
• Improved traceability and compliance enforcement
• ~97% on-time delivery performance in production use

Built multiple interactive applications and educational experiences in collaboration with designers and stakeholders.

Examples:

• narrative-driven hidden-object game (1948)
• accessibility-focused RPG (El bosque de Hiria)
• educational puzzle systems (Constelaciones)
• interactive e-book systems (El cactus de la memoria)

Focus areas:

• deeper system design understanding (distributed systems, scaling patterns)
• stronger backend architecture decisions in .NET
• improved DevOps and deployment fluency
• transitioning toward senior-level ownership of backend systems

Music composition and improvisation using Ableton Live.

This practice influences my engineering approach: structured systems, controlled variation, and iterative refinement under constraints.

Repositories below reflect systems built from concept to production, with focus on backend design, reliability, and maintainability.
