👋 Hi, I'm Juan David Delgado Guzmán

Senior Software Engineer · Technical Lead · AI & Product Builder

I build products end-to-end — from architecture and backend systems to cloud infrastructure, frontend experiences, and AI-powered capabilities.

My work focuses on distributed systems, cloud-native platforms, product engineering, and applied AI, with a strong emphasis on building secure, scalable, and maintainable software.


🚀 About Me

I'm a Senior Software Engineer and Technical Lead with 4+ years of experience building SaaS platforms, distributed systems, and AI-powered products.

I work across the full product lifecycle:

  • Product and technical architecture
  • Backend APIs and distributed systems
  • Frontend applications
  • Cloud infrastructure and DevOps
  • AI/LLM integrations and agentic workflows
  • Production reliability, security, and performance

I also use AI as part of the engineering process through Spec-Driven Development, automated testing, AI-assisted code review, and specialized validation agents for security, performance, and code quality.

🤖 How I Build With AI

I don't use AI only as a coding assistant.

I integrate AI into both products and the software development lifecycle:

Product Requirements
        ↓
Specifications
        ↓
AI-Assisted Implementation
        ↓
Automated Tests
        ↓
Validation Agents
 ├── Security
 ├── Performance
 └── Code Quality
        ↓
Human Review
        ↓
CI/CD → Production

This allows me to move fast while keeping architecture, quality, security, and maintainability as first-class concerns.
