Hi, I'm Javier.
I build smart things for the web.
Specialized in developing robust full-stack applications, integrating state-of-the-art LLMs, and setting up automated cloud infrastructure.
Building robust architectures and intelligent web products.
I am a Full-Stack Software Engineer with a strong background in designing scalable backends, clean frontend experiences, and production-ready cloud environments.
My core expertise centers around Python for backend APIs, data pipelines, and AI integrations (such as LLMs and local stable diffusion workflows), alongside deep proficiency in Ruby and Ruby on Rails for rapidly shipping elegant, convention-over-configuration web applications.
From modern TypeScript/Next.js interfaces to container orchestration with Docker and Kubernetes, I bridge the gap between heavy backend logic and seamless user interactions.
Python, Ruby & Rails
Extensive experience building maintainable business logic, REST APIs, and monolithic/modular web apps.
AI & LLM Integration
Connecting models (Whisper, VOSK, local SD) into full-stack applications with real-time tracking.
DevOps & Cloud
Automating deployments with Docker, Kubernetes, Nginx, and GitHub Actions CI/CD pipelines.
Tech Stack
Technologies and tools I use to bring ideas to life.
Featured Projects
Real-world applications, client work, and technical tools I've built.
A professional, high-end e-commerce and portfolio web application built for a fashion designer. Features elegant visual layouts, responsive design, and optimized performance for brand presence.
Web application that transcribes meeting audio using Whisper/VOSK and generates concise summaries and task lists via LLMs. Features real-time tracking, MinIO storage, and PDF export.
Full-stack application allowing users to generate custom tattoo designs from text prompts, overlay them on images, and manage artwork using local Stable Diffusion and Flask.
A custom-built VPN management tool developed to automate and simplify deployment, configuration, and monitoring of VPN services using container orchestration.
