About Slim

Fullstack engineer with 10 years of experience, including immersion in a deeptech startup in San Francisco (cryptography & AI) and missions for major transport clients (ECS, SNCF).

I am currently based in Colombia, so I logically offer a lower rate.

I design and deploy custom-built agentic pipelines to automate your business workflows, finding the best balance between model performance and inference cost.

My approach: leverage open-source and proprietary technologies while respecting European regulatory compliance (GDPR, AI Act).

Main Expertise:
AI & LLM Engineering

Custom agentic pipeline architecture for business context
Model benchmarking and selection (open source vs. proprietary) — cost/performance optimization

Document analysis and processing (extraction, structuring, classification)

RAG (Retrieval-Augmented Generation) — document search + real-time web connection

Image processing (vision, OCR, multimodal)

Development
Backend: Go, Python
Frontend: React, Next.js
Infra & DevOps: Render, Hetzner, GitHub Actions
AI Tooling: Cursor, Ollama, vLLM, OpenRouter, Perplexica
