Senior Full-Stack Engineer · Remote across the EU

AI automation and custom systems for product teams.

I'm Pablo Llorens, a senior full-stack engineer with 15+ years building production web systems. I help product companies automate manual work, add AI features to existing products, and solve hard backend problems — with testing, CI/CD and code that stays maintainable.

Serviceswhat i do

Three ways I help — led by AI automation.

01 / primary

AI Automation & Integration

Automate manual processes and add AI features to the systems you already run. I integrate AI the way a senior engineer would — measured, tested and maintainable — to solve real problems, not ship throwaway demos.

Document & invoice data extraction
Internal search over your own documentation (RAG)
Support triage & routing
Workflow automation
LLM-powered features inside existing products

Senior engineering discipline applied to AI: testing, CI/CD, code you can keep.

Backend & Custom Integrations

Backend development and the integrations that hold a product together. I take on the hard technical problem — not “whatever you need built”.

API design & complex system integrations
Performance optimization
Modernizing existing systems
Flexible stack: PHP/Symfony, C#/.NET, Python

Fifteen years of shipping backends that hold up under real load.

Technical Consulting & Architecture

Architecture decisions before you build, technical audits, and rescuing or modernizing existing projects. Advisory work where 15 years of watching systems evolve actually matters.

Architecture & technical due diligence
Code & system audits
Rescue / modernization plans

A clear read on what to build, what to fix, and what to leave alone.

Selected workcase study

Proof, not promises.

menaki.app

Menaki — an AI-integrated product, built end to end.

A meal-planning web app I designed and built solo. It's a concrete example of what I mean by AI integration with engineering discipline: AI turns messy, unstructured input into clean structured data, it runs in production, and the code stays maintainable.

Multimodal data extraction
Paste text, a URL, or a photo of a recipe — an LLM normalizes any of them into a structured schema. The same pattern as invoice/document extraction.
AI with cost & reliability control
AI-generated step illustrations (FLUX), behind a tiered, fallback-protected model setup so a single provider hiccup never breaks the feature.
Full-stack, in production
Next.js, PostgreSQL and Vercel; auth, rate limiting, image storage and a 6-language UI — shipped and maintained, not a demo.

The same approach I bring to client work: extract → automate → integrate, with tests and CI/CD.

Why work with metrack record

Plain facts, not a pitch.

15+years building production systems

50+projects shipped

4languages used in production

15+ years in production

Building and architecting web systems that run in production, not prototypes that get thrown away.

Multi-language stack

PHP/Symfony, C#/.NET, Python and TypeScript/React. I pick the right tool, not the only one I know.

Engineering discipline

TDD, CI/CD, code review and Docker as a default — so the work stays maintainable after I hand it over.

Senior, hands-on

Former CTO of a biotech startup (computer vision, C++/Python) and 4 years of side work in quantitative systems.

How I workengagement

Remote, in English, project or retainer.

Remote-first

100% remote across the EU. Working language is English. No travel, no overhead.

Project or retainer

Fixed-scope projects or a monthly retainer for ongoing work. Whatever fits the problem.

Tested & reviewed

Everything ships with tests, CI/CD and code review. You get code you can keep building on.
