What I'm looking for

I'm open to opportunities where I can solve complex problems, scale systems, and make a real impact.

At Intelitax, I develop solutions for financial process automation and large-scale document processing. I implement ETL pipelines to clean, normalize, and consolidate financial data from CSV, Excel, and TXT files.

I developed OCR systems that extract and structure information from PDFs using image processing. I also built multi-criteria correlation engines for bank reconciliation and financial data validation.

I designed modular architectures focused on scalability, resilience, and maintainability, and implemented business workflow automation to reduce manual processes and operational errors. I also participated in developing graph-based solutions and processing large volumes of data.

Previously, at Ingeniería Integral Consultores México, I developed Python analysis scripts for technology requirements and supported IT infrastructure. I'm open to opportunities where I can solve complex problems, scale systems, and make a real impact.
