Hi, I am Gonzalo Jimenez Chango

• Built Python extractors and validators for ministry-facing report review, focused on self-control, verification, and concrete strength test nonconformities.
• Created PDF extraction templates for laboratory reports, accelerating the load of hundreds of strength and water penetration tests during 2025/2026 internal migrations.
• Cleaned and normalized technical data before final upload: certificates, company names, group prefixes, spacing, codes, and inconsistent formats.
• Applied the Spanish Structural Code and the UNE-EN 932/933 families to interpret relevant requirements and test methods.
• Applied audit learning across aggregates, precast products, bituminous mixtures, and ISO 14001-related environmental documentation.
• Supported the definition of technical scope documents for the upcoming ISO 45001 certification work.
• Prepared audit-time calculations and criteria aligned with the standard and references such as IAF MD 5 / MD 22.
• Updated the environmental legislation for the technical areas required by the national accreditation body (ENAC) as part of the accreditation process.
• Reviewed and technically accepted water penetration test results in concrete submitted by laboratories and clients.
• Contributed to SIGECER's transition toward a more self-service digital workflow, where companies fill in part of the required data.
• Handled data uploads and supporting files needed during the internal restructuring process.
• Helped improve internal workflows to reduce team load and speed up request processing.
