Hello, I'm Eduard Ferré

AI & Data Engineer. Building tools that actually work._

Eduard Ferré, AI / Data Engineer

+3 years of professional experience. AI / Data Engineer at Carver Advanced Systems. Currently working on projects involving LLMs, Knowledge Graphs with RAG, and Mainframe code analysis (COBOL/JCL) using AI. Living in Barcelona, pursuing an online master's degree in Project Management at EAE Business School, specialising in Agile Methodologies and Digital Transformation. Passionate about building scalable data solutions and leveraging AI to drive strategic decisions.

    AI / Data Engineer

    Carver Advanced Systems

    Built a multi-agent AI system (Python, OpenAI, Azure) that traces data lineage across ~80,000 COBOL/JCL Mainframe files — around 24.5M lines of code — for a large European financial-automotive group. Sole owner for the first 8 months, from architecture to delivery and executive-level client contact; now co-leading a team, with regulatory deliverables compliant with ECB requirements.

    Architected a Knowledge Graph + RAG codebase-intelligence platform for a banking and insurance group, adopted by most of its technical and business teams: a multi-repository graph (COBOL/JCL, Java, JS/TS, Python) built via AST parsing (ANTLR4), enriched with LLM descriptions and business context, indexed in Neo4j and queried with GraphRAG (BM25 + embeddings, neighbour expansion, LLM traversal through tool calling). Also built a guardrailed RAG chatbot for an international insurer's website that routes users to the right section (in UAT, production launch planned).

    Designed a LiteLLM-based AI governance proxy shaped as a product for external sale.

    Other work: a sales-training pipeline, an accounting application for a Spanish public administration body, and client PoCs.

  2. Software Engineer

    Giesecke+Devrient

    Developed key modules for a multi-tenant remote eSIM/eUICC profile management platform (SGP.22, SGP.32) used by multiple telecom operators — implemented terms-of-use/privacy acceptance flows and an orchestration proxy for dynamic eSIM profile recycling and pooling across devices, enabling massive-IoT use cases such as Spain's DGT V16 emergency beacon. Extracted and audited user data to support the legal department.

    Backend in Java (Spring Boot) and TypeScript (Node.js/Express), frontend in Angular, over Oracle SQL and MongoDB — working Scrum/Agile with Jenkins for CI/CD and SonarQube as the quality gate.

  3. Researcher

    Universitat Politècnica de Catalunya

    Research and characterization of different IPV (indoor photovoltaic) cell technologies under varying indoor light conditions, as part of the EU-funded project CELISA — efficient harvesting of indoor light energy for autonomous sensors.

    Owned the full experimental cycle: circuit design and instrumentation (KiCad, BenchVue, AvaSoft), measurement campaigns under controlled illuminance and temperature, and data analysis in Matlab — work that ended up in four peer-reviewed publications.

ZenithFi - Personal Finance App

ZenithFi is a modern, elegant personal finance and budgeting web application built for clarity and ease of use. Track income and expenses, manage spending categories with unique colors and emojis, and set budget limits. Features a customizable dashboard, deep analytics with charts, internationalization (English, Spanish, Catalan), dark mode, and secure session-based authentication.

eGym - Fitness application with Machine Learning

eGym is an iOS application developed for my final Telematics Engineering bachelor's thesis. The application is a combination of a social network, a fitness tracking app and a personal trainer powered with machine learning. All the data is stored in two databases (access control and data storage) via an API Rest. The machine learning is based on a personalized model, which has been trained with multiple videos of different exercises.

about-me About Me

I'm Eduard, although everyone knows me as Edu! At 15 years old, I learned programming logic and was able to create a Brick Breaker with Visual Basic. Years later, I pursued a double degree in Aerospace Systems Engineering and Telematics Engineering at Universitat Politècnica de Catalunya (UPC).

Along the way I built projects with just about every technology I could get my hands on, but it was in my final year — while researching indoor photovoltaics at UPC, work that ended up in four peer-reviewed publications — that I decided software was where I wanted to be, and joined G+D.

There I learned what it really means to work in an Agile team: shipping to production, reviewing other people's code, and picking up whatever the ticket needed. In parallel I built eGym, an iOS app with a computer-vision model, as my final degree project.

Later, I pursued a master's degree in Big Data Analytics at Universidad Carlos III de Madrid (UC3M), where I deepened my knowledge in data science, machine learning, and large-scale data processing.

Today, I work as an AI / Data Engineer at Carver Advanced Systems, where I lead projects at the intersection of AI and data — building solutions with Large Language Models (LLMs), Knowledge Graphs with RAG, and Mainframe code analysis (COBOL/JCL) using AI. On the side I'm taking a master's in Project Management at EAE Business School, because knowing how to build something is only half of getting it delivered.

Outside of work you'll find me at the gym, cooking, or taking apart some side project that nobody asked for. I like problems that look messy at first and turn out to have a clean shape underneath.
