Andrey Quesada

Software Engineer | Full-Stack Development & AI Workflows

Building production-grade full-stack applications with AI-powered workflows. Recently completed intensive Full-Stack program (Lyfter, 2025-2026) with 4+ production-quality projects. 7+ years prior experience at Intel building automation systems for silicon validation at scale.


Recent Work (2025-2026)

Built complete applications from scratch demonstrating modern software engineering:

Project Description Stack
CaterPro Full-stack catering platform with 60 endpoints, 85% test coverage Flask, PostgreSQL, Redis, JWT, Vanilla JS
Multi-Agent Web Dev AI-powered workflow with 6 specialized agents Python, CrewAI, LLMs
Pet E-commerce API RESTful API with 42 endpoints, 78% test coverage Flask, PostgreSQL, JWT Auth
Todo List App Modular frontend with MVC architecture HTML, CSS, Vanilla JS, Vite
Software Engineering Lab Data structures, algorithms, SQL, GUI app Python, SQL, Testing

What I Build

Full-Stack Applications

  • End-to-end ownership: frontend (JavaScript, HTML/CSS, Vite) + backend (Flask, PostgreSQL, Redis)
  • RESTful APIs with layered architecture (controllers → services → repositories)
  • JWT authentication & role-based access control
  • Database design, optimization, and caching strategies
  • Comprehensive testing (unit + integration)

AI Workflows

  • Multi-agent systems with CrewAI for automated development
  • LLM orchestration and prompt engineering
  • Automated code generation and documentation
  • Strategic AI integration in production environments

Production Engineering

  • Security best practices from Intel production environments
  • Scalable architectures and performance optimization
  • Test-driven development with high coverage
  • Clean code principles and maintainable systems

Intel Experience (2018-2025)

Production automation for silicon validation:

  • reduction in critical validation timelines
  • 30% test time reduction (hundreds of thousands USD saved)
  • faster data analysis through pipeline automation
  • Led teams of 3-4 engineers on production systems
  • Applied AI agents and LLMs to accelerate test creation and validation automation, integrating outputs into production workflows

Technologies: Python, C#, SQL, Linux, data pipelines, test automation


Currently

Focused on Backend Systems Engineer roles where I can:

  • Design scalable backend architectures and production APIs
  • Integrate AI as an engineering multiplier rather than a gimmick
  • Apply production‑grade standards to modern web development
  • Deliver maintainable, well‑tested systems that scale
