Back to original languageAbout Adrian
Design and development of AI-powered digital products | AI, automating and digitizing processes for businesses to grow with efficiency.Technology should adapt to the business, not the other way around.
I have over 17 years of experience as a Fullstack developer, with a strong foundation in architecture and execution. I work on end-to-end projects: from functional definition to deployment and evolution, always with a focus on product, user, and results.
I have worked for companies such as BBVA, Caja Rural, and Deutsche Telekom, and have developed AI solutions in production for Mutua Madrileña and products used by Carrefour and Toyota.
In recent years, I have specialized in:
- Systems with LLMs and multi-agent architectures
- RAG solutions for automation and document processing
- Assisted software generation and specialized agents
- Secure, auditable, and production-ready AI systems
My focus is on **context and the correct use of knowledge**: prompt design, skill definition, knowledge structuring, and continuous evaluation (Opik), which allows for building reliable and consistent systems.
I also value when to use AI and when not to, combining it with deterministic logic or script generation to reduce costs and dependency, enabling scaling to a high volume of users.
Technological specialization:
- E-commerce and marketplaces
- SaaS and web applications
- Mobile apps connected to backend
- Software with complex logic and AI integration
Stack: React Native, Next.js, Rails, Node.js, Python, AWS, GCP, Docker, Kubernetes, LangChain, RAG, n8n, PostgreSQL, MongoDB, Redis, Appsec
Results-oriented, I bring a global technical vision and experience in building real and scalable systems.
