About
Hello! I’m Esteban Link to heading
I’m a passionate software engineer with over 10 years of experience building scalable, AI-integrated solutions. I specialize in Python development, Flutter mobile applications, and API-driven microservices, helping businesses leverage cutting-edge AI technologies to solve complex data challenges.
What I Do Link to heading
AI & Machine Learning Link to heading
I work extensively with LangChain and LangGraph to orchestrate sophisticated AI workflows. Whether it’s integrating local models from Hugging Face, working with Llama, or leveraging the OpenAI API, I create systems that transform natural language processing and deliver data-driven insights.
Vector Databases & RAG Systems Link to heading
I have hands-on experience with Chroma and Pinecone for efficient embedding storage and retrieval. This expertise enables me to build powerful retrieval-augmented generation (RAG) systems that enhance LLM applications with relevant, contextual information.
Cross-Platform Mobile Development Link to heading
I build native-quality mobile applications using Flutter, delivering consistent user experiences across iOS and Android platforms. My Flutter expertise allows me to create performant, beautiful apps that integrate seamlessly with backend APIs and AI services.
API Development & Data Processing Link to heading
I design and build robust RESTful APIs using FastAPI and Django REST Framework. My experience includes creating efficient ETL pipelines that handle both structured and unstructured data from various external sources, ensuring seamless data flow and processing.
Cloud & Infrastructure Link to heading
My technical toolkit includes:
- Databases: Redis, MongoDB, PostgreSQL, MySQL
- DevOps: Docker, Ansible
- Cloud Platforms: Azure, AWS, DigitalOcean, and other cloud service providers
- Deployment: Automated CI/CD pipelines and scalable infrastructure management
My Approach Link to heading
I believe in building solutions that are not just technically sound, but also maintainable, scalable, and aligned with business objectives. Whether you’re looking to integrate AI into existing systems, build new data-driven applications, create cross-platform mobile experiences, or optimize your current infrastructure, I’m here to help turn your vision into reality.
