Most AI projects I see are not failing at the model. Teams already have access to GPT, Claude, APIs, automation tools, or a chatbot pilot. The problem is that the layer underneath is unowned: whether the data feeding the model is current, whether the retrieval is actually accurate, whether the agent handled the edge case correctly, or whether the pipeline behind it even ran last night. That is the layer I build. I build the data and AI layer behind products and day-to-day operations: RAG chatbots, LLM integrations, AI agents, data pipelines, vector search, validation and data quality checks, monitoring, and reporting across the tools your team already uses. Recent results include: Built a real time ML pattern detection system for trading charts, delivered with a 5 star review on a $2,300 contract Shipped production ETL pipelines processing over 100K records per day Deployed ML models achieving over 90% accuracy Reduced a CRM reporting cycle from 3 days to 4 hours My background combines production data engineering at Starzplay and Dubizzle Labs with an MS in Big Data and Machine Learning from the University of Bonn, where my research covered transformer models, allowing me to work across both the data layer and the AI layer. Technologies I regularly work with include Python, SQL, OpenAI API, Claude, LangChain, RAG, Pinecone, Chroma, Snowflake, AWS, PySpark, n8n, REST APIs, webhooks, and Power BI. Whether the goal is a chatbot that answers correctly, an agent that runs unattended, cleaner data, or reporting your team can trust, I focus on building AI systems that are reliable, accurate, and easy for teams to operate. I work in English and German (ich betreue deutschsprachige Kunden gerne auch auf Deutsch). Send me your current data, AI, or reporting challenge, and I'll identify the bottlenecks and explain what I'd build first.

I'm a data professional with a Bachelor degree in computer science, with 8+ years of experience in the field and have been working in small and big data enterprise solutions. During my professional path, I worked in several roles like DBA, Data Architect, Data Engineer, Data Governance and Business Analytics team support. My experience comes from hybrid environment projects with cloud providers like AWS, Google and Azure. I can mention some of the most challenging projects in my professional career where I am proud to produce an impact in the organizations. The actual Chilean Public Education payment service, which managed almost 3,2% of the country's PIB can calculate and assign the Education money for every public school in the country using variable metrics managed by user, my expertise in Databases and integrations was key in the actual calculation workflow process. I was able to developed a service to recollect Chilean Public transportation data from real-time social network and combine with the buses GPS data for analytics, so the Managers could make decisions for quality service improve from the service user perspective taking actions rapidly. I was part of the team that create and deploy the first Africa online tax service in Kenya, where I took in charge of the modeling and support of the Oracle operational database, the service was a game changing, lowing in big manner, the cost of the tax recollection in Kenya. And lastly I design and had feed the Datawarehouse of a Chilean financial big company with the data required that allowed to the company made the correct decision about what king of products needed to focus. All of it, with a mix of database services like Azure SQL Server, GCP Bigquery, MongoDB and PostgreSQL. With the work on mixed environments and budgets, I can mix open-source technologies like low-code solutions like Pentaho, Airflow, db and Processmaker, with proprietary services in the cloud like lambda functions, Athena, Google Compose, Azure ADF or Glue, plus coding skills like SQL, python, Java and Regular Expressions (for text data query). I also have experience with Data visualization tools like Google Data Studio, Clickview, PowerBI, SSRS, Webfocus and Pentaho Reporting Services, knowledge of it because of the need to support BI Teams in some projects. Its seems likely that I missed a more specialized technical profile, but it was the result of the need to work with disparate clients and industries, however I feel very confident with the whole enterprise data journey path, from data modeling and processing to data visualization and it allows me to see the big picture in data solutions implementations.
