Full Stack Developer & Systems Analyst

Building robust software with analytical rigor.

Hi, I’m Carlos Abdiel. I combine over 4 years of professional web development with React and PHP/CodeIgniter, and mobile development with React Native, with a background in Philosophy. I break down complex business problems and build solutions for electronic invoicing, CRM automation, and Artificial Intelligence integrations.

01 · Projects & experience

Complex problems. Production solutions.

The context, technical decisions, and my contribution behind each project.

Menú QR + IACurrent project

Digital menus with AI recommendations

React / Next.jsNode.jsOpenAI API

The problem

PDF menus are hard to read on mobile, lack interaction, and do not help diners discover dishes or pairings.

< 1.5 s AI response latency through caching and prompt optimization.
100% of menu ingredients mapped for stock-aware recommendations.

Read technical case study

Technical decisions

Dynamic OpenAI recommendations, structured backend prompts, and JSON responses to reduce incorrect answers and simplify rendering. Local caching reduces latency.

My role and solution

Sole developer: responsive interface, Node.js API, and ingredient filtering rules for personalized suggestions.

03 · My approach

Philosophy and code. A shared logic.

People often ask how my Philosophy degree connects to software engineering. For me, both share an origin: breaking complex problems into clear, logical, unambiguous structures. This background helps me understand real business needs before writing the first component or SQL query.

In over 4 years working on invoicing platforms such as FiscalCloud and enterprise systems at Ciudad Maderas, I have applied this rigor to delivering stable solutions: data flows, digital signatures, XML, and intelligent automation.

I believe software should be readable and maintainable by any team. I care about clean code, version control with Conventional Commits, and documentation. I want to bring technical value, strategic analysis, and a proactive mindset to a team solving real problems.
