Freelancer profile translated to English.
Back to original languageAbout Andrés
I am a Technical Engineer in Computer Science from the University of Málaga. I currently have over 15 years of experience in web and mobile application development. My early years were spent in the corporate world, where I worked with clients such as INTA (National Institute of Aerospace Technology), the Ministry of Finance, or PwC (PricewaterHouseCoopers). Since 2019, I have been working exclusively as a remote freelancer.
I am a FullStack developer, which means I am comfortable on both the Backend (Node.js/Nest.js, .Net, Java/Spring, PostgreSql, MySql, MongoDB, etc.) and Frontend sides. On the Frontend, I have carried out developments with the latest frameworks, especially Vue (Nuxt, Vuex) and React.js (Next.js, Redux). In the mobile application realm, I have primarily developed with React Native.
I am currently exploring the potential of LLMs (Large Language Models) as engines to power applications and have experience as a prompt engineer. I am also familiar with OpenAI and Deepseek APIs, as well as the LangChain framework for integrations in web applications (assistants, custom chatbots, text search using embeddings, JSON input/output, fine-tuning, RAG, etc.).

Experience
- PhotorekaAI-powered Photo Management App (photoreka.com)FILM AND AVJanuary 2024 - March 2026 (2 years and 2 months)Photoreka is an AI-powered photo curation platform that allows photographers to explore, organize, and build narratives from their archives through semantic and conversational interaction.I led the end-to-end development of the product, combining frontend, backend, and AI systems to transform the photographic archive into a navigable and "queryable" system.Technically, the architecture is based on Vue 3 + Nuxt (SSR) on the frontend, AdonisJS on the backend, and Python services for AI pipelines, deployed on RunPod and Railway.The core of the system combines visual embeddings (CLIP), semantic search, and a RAG (Retrieval-Augmented Generation) approach. On top of this, I designed an agentic chatbot with LangChain, based on the latest generation Gemini and GPT models, capable of interacting with the user's archive, retrieving relevant context, suggesting collections, or evaluating technical and artistic aspects of the catalog.Additionally:- Implemented advanced semantic search using embeddings and NLP.- Developed a 2D/3D Atlas using dimensionality reduction techniques to explore the archive as a semantic space.- Built an artistic scoring and archive analysis system.- Implemented a complete ingestion and analysis pipeline, with integrations like Lightroom (luma) and Google Photos.
