Description

Do you want to take AI to your company beyond the demo? I help you integrate language models (LLMs), agents, and automation into your product or processes, with code that holds up in production.

I have 6 years of software development experience, with the last few years focused on AI systems: agents that perform real tasks, assistants connected to your own data (RAG), automation of repetitive processes, and API integration of models. I don't just stay at the prototype stage: I design the architecture, connect it to your systems, and get it running.

How I can help you:

• Integration of LLMs and AI agents into products or internal processes

• Chatbots and assistants on your documentation or data (RAG)

• Automation of tasks and workflows (tracking, notifications, data extraction)

• Backend and API development in Python/FastAPI (and fullstack when needed)

· Full stack and web development.

Usual stack: Python, FastAPI, LangGraph, React, PostgreSQL, Docker, Celery/Redis. I have a master's degree in cybersecurity, so I take care of your data's privacy and security from the design phase, not as an afterthought.

Direct work: I'll tell you what makes sense to build, what doesn't, and why. Tell me your case and I'll propose the simplest approach that solves the problem. I also offer consulting services on your project and its viability in the current technological environment.
