Turning data into decisions, and ideas into intelligent systems.
Hi! I'm Juan, a Data Scientist and AI Engineer. In September 2026 I graduated from Pontificia Universidad Javeriana (B.S. in Data Science, cum laude) with the highest GPA of the program — the Orden al Mérito Académico Javeriano and the Honor Mention for Best Academic Average. I work as an independent Data & AI Engineer — most recently delivering a data pipeline for Alteon Insurance through Imuko — after leading Computer Vision at Vigías de Colombia, and I love understanding a problem deeply before solving it with data.
Experience
A track record of delivering value across data, AI, and engineering.
Freelance Data & AI Engineer
Independent data and AI engineering for clients. Most recent engagement — through Imuko — building a data pipeline for Alteon Insurance, delivered in July–August 2026.
AI Engineer · Computer Vision & LLM/RAG
Led the Computer Vision side of a full-stack video intelligence system — a hybrid model ensemble (YOLO, D-FINE, RT-DETRv2, PaddlePaddle) that automates event detection and metadata generation from live camera streams — served as containerized APIs (Docker, FastAPI / Flask) on AWS and Azure ML / Databricks, plus NLP / LLM and RAG components integrated into Medallion-architecture data pipelines.
Database Administrator
Developed a robust SQL database schema and relational model for a new public health platform dedicated to the Colombian teaching workforce, ensuring data integrity, scalability, and support for longitudinal health tracking.
Junior Data Scientist
Designed and implemented automated dashboards for directors to monitor organizational health and process efficiency, enabling data-driven decision-making across the organization.
Analyst
Developing a comprehensive market analysis pipeline in Python integrating fundamental and quantitative methodologies. Leveraging yfinance API for financial data extraction, implementing NLP for market sentiment analysis, calculating technical indicators like EMA, and incorporating risk management logic to drive automated trading algorithms.
Database Administrator
Architected and structured complex datasets by normalizing schemas and developing robust ETL pipelines for analytical processing.
Administrative Assistant
Optimized university course scheduling by aligning departmental requirements with student enrollment needs.
Advanced Programming Tutor
Guiding students through the core pillars of OOP using Java, the mechanics of programming logic, and the intricacies of C++ pointer manipulation.
Education
Científico de Datos — Pontificia Universidad Javeriana, cum laude, highest GPA of the program.
B.S. in Data Science (Científico de Datos)
Graduated cum laude with a 4.53 / 5.0 cumulative GPA — the highest of the Data Science program. Thesis on the interpretability of Transformer models: mapping conceptual circuits in GPT-2 Medium through causal interventions that simulate semantic aphasia.
- Orden al Mérito Académico Javeriano (Sep 2026) — the university's distinction for graduates with an outstanding final cumulative GPA.
- Mención de Honor al Mejor Promedio Académico (Sep 2026) — Facultad de Ciencias honor mention for the best cumulative GPA in the Data Science program.
- Academic Excellence Scholarship (2023-1) — highest cumulative GPA in the Data Science program.
- Outstanding High School Graduate Scholarship (Beca Bachiller Destacado) — Pontificia Universidad Javeriana.
- University representative at the H4CKFOREDU International Hackathon (Universidad Pontificia de Salamanca, 2024); participant in the UN Datathon 2024.
Featured Projects
The work behind the experience — real systems in production and research.
VIGIAS-IA: Real-Time Video Analytics
Video intelligence system for security where I lead Computer Vision: live camera streams processed in real time with a hybrid model ensemble on NVIDIA DeepStream.
PIPE-IA: Generative AI for Network Analysis
Generative-AI platform (Condor AI) that turns complex network and territory data into clear, actionable strategic insights.
Generative AI for Fiscal Control
Generative AI applied to fiscal oversight: automates the analysis of financial and regulatory data, flags anomalies, and produces structured reports.
View case studyEAOA: Autonomous Operations Ecosystem
Multi-agent system that orchestrates specialized AI agents — persistent memory, function calling, agentic workflows — to automate business processes autonomously.
Tequendama: AI Insurance Platform
Conversational insurance assistant built for the Colsubsidio 30X hackathon — web chat, live voice and WhatsApp: it profiles, quotes, verifies identity (KYC), collects payment and issues the policy without a human in the loop.
PULSO: AI Emergency Routing
Built at Platanus Hack 26 (Bogotá, Emergencies track): turns a paramedic's voice dictation into a structured clinical case and routes the patient to the hospital that can actually receive them — by real travel time and enabled services, not just distance.
AI Voice Agent for Collections
Real-time outbound voice agent for credit-card collections: Deepgram speech-to-text and text-to-speech with an LLM brain, an FDCPA-compliant script, call persistence and a chat fallback.
Financial Analytics & Market Prediction
Quantitative market pipeline: NLP sentiment, technical indicators, and CNN-LSTM price prediction feeding automated, risk-managed trading.
Thesis: Interpretability of Transformer Models
B.S. thesis (Javeriana, 2026): mapping conceptual circuits in GPT-2 Medium with causal interventions — ablations and hooks that simulate semantic aphasia — to understand how Transformers represent meaning.
FOMAG Database Architecture
SQL schema and relational model for a national public-health platform serving Colombia's teachers — built for integrity, scale, and longitudinal tracking.
