About me

Engineer based in Madrid, Spain, available immediately for 100% remote projects in Python, AI/ML, computer vision, web development and embedded systems. I focus on hands-on delivery and clear milestones.

Computer VisionEmbedded SystemsPython (Programming Language)Machine LearningOpenCVGenerative AIFastAPI
I am an engineer with professional experience since 2013 and nine years working with Python, machine learning and computer vision, including three years in generative AI and AI agents.

I build Python APIs and backend services with FastAPI, Docker and SQL, AI agents and RAG systems with LangGraph/LangChain, and web interfaces with React and TypeScript. My production work includes multimodal inspection agents, document and image retrieval, tool integrations, model routing, tracing and streaming interfaces. I have also worked with Node.js and the APIs of CVAT.

My computer vision experience includes PyTorch, OpenCV, TensorRT, detection, segmentation, dataset creation and model optimisation on NVIDIA edge hardware. I have worked with several NVIDIA Jetson models and Raspberry Pi.

I also have experience in electronics, PCB design with Altium, and embedded firmware using Arduino, PIC, STM32 and ESP32. For hardware projects, the client must provide the necessary equipment or remote access.

I am available immediately for 100% remote projects from Madrid, Spain: AI and ML, computer vision, Python, web development, automation, technical integration and embedded systems. I focus on hands-on technical delivery and clearly defined milestones. I do not take mobile application development projects.

Project history

AI Agent Engineer

Unusuals
Built and operated a multimodal inspection assistant for a Spanish electricity-grid client. Rebuilt the agent as a multi-step ReAct loop with LangGraph and specialised tools for image analysis, document retrieval and reports. Implemented model routing and failover, guardrails, LangSmith tracing, streaming and a React interface. Integrated Microsoft Teams and Microsoft Graph API, with end-to-end tests for releases. Fully remote technical delivery.

Machine Learning Engineer | Freelance

Alvea
Delivered two AI MVPs in two weeks and developed generative AI, agent and RAG solutions. Built Python/FastAPI backends, React/TypeScript interfaces and deployment workflows, gathering requirements directly from clients. Full-time freelance collaboration, 100% remote from Spain.

Machine Learning Engineer | Freelance

CIVIR
Developed a LangChain voice agent for kitchen and dining-room workflows, using voice activity detection, buffered audio and Whisper to send only real speech for transcription. Built Python/FastAPI APIs, web interfaces and RAG integrations, with Kubernetes deployment. Full-time freelance collaboration, fully remote from Spain.

Technical Lead

Bravent
Technical leadership for a generative AI initiative on Azure: architecture, technology selection and risk assessment. Fully remote, full-time role; the client stopped the programme.

Computer Vision & Robotics Engineer

Sener Aeroespacial
Developed perception systems for autonomous ground vehicles: detection, classification, semantic segmentation and depth estimation. Built real and synthetic datasets, fine-tuned vision networks and optimised inference with TensorRT on NVIDIA AGX Orin, reducing latency and VRAM by about 30% with about 2% accuracy loss. Created an annotation workflow that reduced image labelling from hours to minutes.

AI, Hardware & Firmware Engineer

Arquimea
Developed shared hardware and low-level firmware for three UAV models. Built a YOLO detector that replaced a commercial module, saving about EUR 2,000 per unit, and deployed detection models on NVIDIA Jetson. Designed electronics and firmware for flight control and airport bird-dispersal systems. Developed an experimental visual geolocation MVP, clearly separate from production systems.

Development HW & FW Engineer

Indra
Designed control PCBs and embedded hardware/firmware for an autonomous helicopter programme. Worked on electronics development, microcontrollers, testing and engineering documentation.

Intern — HW & FW Engineering

Indra
Engineering internship working on electronics, embedded hardware and firmware development, testing and project documentation.
