Computer Engineering professional and Technical Lead at the Ministerio de Educación Pública (MEP), specializing in system modernization, and secure application architecture.

• Engineering Philosophy: Combines a disciplined full-stack software development background with modern cloud infrastructure, containerization, and high-availability design.
• Technical Leadership: Directed a six-developer engineering team on public-sector digital transformation initiatives, taking sole accountability for system stability, CI/CD deployment optimization, and infrastructure refactoring.
• Cloud & DevOps Orientation: Active practitioner across multicloud environments (AWS, OCI, GCP, Azure), focusing on automated container deployments, infrastructure provisioning, and fault-tolerant architecture design.

• Amazon Web Services (AWS): EC2, ECS (Fargate), S3, VPC Networking, RDS, IAM, Secrets Manager, ALB
• Oracle Cloud Infrastructure (OCI): Virtual Cloud Networks (VCN), Compute, Security Lists, Subnet Routing, High Availability Quorum Design
• Google Cloud Platform (GCP): Cloud Run (Serverless Containers), Compute Engine, Cloud Storage
• Microsoft Azure: Virtual Machines, Virtual Networks (VNets)

• Containerization: Docker Engine, Multi-stage builds, Container Registries, Image Footprint Optimization
• CI/CD & Automation: GitHub Actions, Pipeline Integration, Bash Scripting, Linux System Administration (Ubuntu/Debian)
• High Availability & Resilience: Replica Sets, Active-Passive Architecture, Block-Level Replication, Disaster Recovery Runbooks

• Backend & Web Frameworks: Python (Flask), C# (.NET 8, ASP.NET Core API), TypeScript, JavaScript, React 19, Next.js 15, Node.js
• Mobile Engineering: .NET MAUI (Cross-Platform Android/iOS/Windows), Firebase Integration
• Database Systems: MongoDB (Replica Sets & Aggregations), Microsoft SQL Server, PostgreSQL, Relational Schema Design
• Generative AI & RAG: Google Gemini API, LlamaIndex (Vector Store Indexing), OpenAI Whisper (large-v3 CUDA ASR)

The following repositories represent core engineering competencies across cloud architecture, artificial intelligence, full-stack development, and cross-platform mobile systems:

Serverless Web API, AWS ECS Fargate & CI/CD Pipeline
Tech Stack: ASP.NET Core 8 | Docker | AWS ECS (Fargate) | AWS ECR | GitHub Actions | Entity Framework Core 9 | JWT | OpenWeatherMap API

A containerized RESTful Web API engineered for real-time weather data processing, usage auditing, and serverless cloud execution on AWS.

• Container Optimization: Built using a multi-stage Dockerfile that segregates the SDK build environment from a lightweight, hardened ASP.NET runtime footprint to minimize image size and deployment latency.
• AWS ECS Fargate Architecture: Designed for serverless container execution with custom task definitions, IAM execution roles, and secure container registry hosting via AWS ECR.
• Automated CI/CD Pipeline: Integrated GitHub Actions workflows to automatically build, package, and deploy container updates to ECS Fargate with zero-downtime execution upon every repository push.

Cloud High Availability & Disaster Recovery Architecture (OCI)
Tech Stack: Oracle Cloud Infrastructure | MongoDB 7.0 | Ubuntu Server | Bash | Cisco Packet Tracer

An active-passive High Availability database cluster hosted on OCI featuring zero data loss (RPO = 0) and sub-minute automated failover.

• Core Architecture: Provisioned a multi-fault domain VCN with regional private subnets, implementing customized 2-VM quorum voting logic via a double-vote Arbiter process.
• Enterprise Baseline: Designed a supporting Tier III multi-site network topology in Cisco Packet Tracer featuring BGP Multihoming, OSPF full-mesh routing, and LACP EtherChannels.

AI-Powered Call Center Audio Analyzer & RAG Engine
Tech Stack: Python | OpenAI Whisper | LlamaIndex | Google Gemini 2.5 Flash | React 19 | Flask

An automated speech-to-text pipeline and conversational intelligence tool designed for telephony interaction analysis.

• Speech-to-Text Pipeline: GPU-accelerated local transcription via CUDA-enabled OpenAI Whisper large-v3 with timestamped segment extraction.
• Grounded RAG Architecture: Vector index search using LlamaIndex and Gemini embeddings, protected by strict system prompt guardrails against out-of-context hallucinations.

International Cooperation Management Dashboard
Tech Stack: Next.js 15 | TypeScript | PrimeReact | Tailwind CSS | Node.js

An enterprise dashboard engineered for tracking international agreement lifecycles, project analytics, and financial reporting.

• Modular UI Architecture: Developed with the Next.js 15 App Router and PrimeReact for analytical chart rendering and dynamic data filtering.
• Lifecycle Tracking: Manages multi-phase cooperation proposals, stakeholder deliverables, and real-time status transitions.

Cross-Platform Mobile Incident Tracker
Tech Stack: .NET MAUI | C# | Firebase Realtime Database / Auth | XAML

A native cross-platform mobile application for enterprise field incident logging and tracking.

• Cross-Platform Core: Built on a single C# / XAML codebase targeting Android, iOS, and Windows desktop runtimes.
• Security & Operations: Features role-based access control, real-time ticket state transition updates, comment threads, and advanced status filtering.

Full-Stack Social Network Platform
Tech Stack: MongoDB | Express.js | React (Vite) | Node.js | Socket.IO

A feature-rich web platform built on the MERN technology stack.

• Real-Time Communication: Integrated bidirectional messaging, live activity feeds, and system notifications using Socket.IO websockets.
• Session Security: Implemented JWT-based authentication, user profile management, friendship graph relationships, and content moderation rules.

• AWS Certified Solutions Architect – Associate (SAA-C03) | Amazon Web Services (In Progress, 2026)
• Microsoft Certified: Azure Fundamentals (AZ-900) | Microsoft (In Progress, 2026)
• Google Cloud Computing Fundamentals | Google / PROCOMER Scholarship Program (Expected Oct 2026)
• Bachelor of Science in Computer Engineering | Universidad Latinoamericana de Ciencia y Tecnología (ULACIT)
