Work History

BI Developer

Industrias De Hilos De El Salvador
08.2023 - Current
  • Designed and optimized ETL processes to extract production data from multiple sources (spinning, weaving, dyeing) and load it into a centralized data warehouse.
  • Modeled production datasets in Power BI and SQL Server, enabling efficient analysis of batch performance, machine utilization, and order fulfillment status.
  • Created dynamic dashboards for plant managers to monitor real-time production KPIs, including downtime, throughput, and rejection rates.
  • Designed custom dashboards tailored for executives, supervisors, and process engineers, enabling each user group to track relevant metrics such as production progress, inventory levels, and delivery performance.
  • Developed custom DAX measures and calculated columns to analyze process inefficiencies, cycle times, and chemical consumption trends across departments.
  • Built hierarchical drill-down visualizations to allow users to explore performance by department, production line, machine, or operator.
  • Used SQL and Power Query (M language) to clean and transform raw data from legacy systems and manual logs into usable, structured datasets.
  • Delivered scalable reporting solutions that enabled cross-functional visibility and supported decision-making in continuous improvement, planning, and resource allocation.

Process Automation Engineer

Industrias De Hilos De El Salvador
01.2023 - Current
  • Automated the registration of production batches by integrating data from machines into centralized logs using Power Automate, enabling real-time visibility across departments.
  • Synchronized quality inspection data from the production area with Power BI dashboards, using Make to automate the flow of non-conformance reports to supervisors.
  • Implemented real-time alerts via Slack and Teams using Zapier, notifying key personnel when batches in the Dyeing area exceeded standard processing times, enabling prompt cross-departmental responses.
  • Created automated shift reports by connecting production data from Dyeing machines to formatted Excel or PDF files using Power Automate, which were distributed daily to plant managers.
  • Centralized order tracking by building a Make workflow that linked batch progress from various departments into a shared dashboard, improving coordination and reducing delays.
  • Developed automatic ticketing flows for maintenance requests using Power Automate, triggering alerts and logging requests in Microsoft Lists based on operator input forms.
  • Enabled automatic chemical inventory updates in the Dyeing area using n8n, extracting usage data from production logs and updating shared inventory files used by the Purchasing team.
  • Implemented alert workflows to notify the Weaving team when required yarn batches from Spinning were delayed, using Slack notifications powered by Make.
  • Built an automated feedback loop that consolidated production inefficiencies from the Dyeing area and forwarded summarized reports to the Engineering and Continuous Improvement teams, enhancing data-driven decision-making.

Low-code/No-code Application Developer

Industrias De Hilos De El Salvador
06.2022 - 08.2023
  • Converted manual data capture processes into digital workflows using Microsoft 365 tools, significantly reducing data processing time and enabling real-time visibility.
  • Designed and deployed internal business applications with Power Apps, streamlining operational requests and approvals across multiple departments.
  • Collaborated closely with stakeholders to understand operational needs and developed custom Power Apps to capture production-related data efficiently and accurately.
  • Built executive-level applications to track production batches, monitor inventory in real time, and visualize order progress, supporting strategic decision-making.
  • Automated approval workflows using Power Automate, reducing manual intervention and improving the turnaround time of administrative processes.
  • Developed user-friendly dashboards with Power BI, integrating real-time data from SharePoint, Excel, and internal databases for better monitoring and performance tracking.
  • Created multi-step workflows using Make (Integromat) to connect tools like Outlook and Teams, facilitating cross-functional collaboration.
  • Maintained and continuously improved low-code solutions by gathering user feedback and adapting apps to evolving business processes.

Data Analyst

Industrias De Hilos De El Salvador
01.2022 - 06.2022
  • Analyzed production data from various stages of the manufacturing process to identify trends, deviations, and opportunities for operational improvement.
  • Digitized and structured non-digital data by manually entering production records, quality logs, and machine reports into centralized spreadsheets and databases.
  • Generated and presented weekly production and quality reports to the Production Engineer, highlighting key metrics such as output volume, defect rates, and machine efficiency.
  • Built summary tables and graphs in Excel to visually represent production performance and facilitate faster decision-making.
  • Monitored and validated data consistency across multiple sources to ensure accurate reporting for key stakeholders.
  • Identified recurring quality issues through data pattern analysis, supporting the quality control team with actionable insights.
  • Collaborated with supervisors to clarify missing or inconsistent data entries, ensuring the completeness of weekly production datasets.
  • Used statistical tools such as standard deviation, control charts, and box plots to analyze production variability and detect anomalies in output across shifts and machines.

Quality Control Analyst

ProCaps Labs
05.2021 - 12.2021
  • Conducted physical and chemical testing of finished pharmaceutical products to ensure compliance with internal specifications and regulatory standards.
  • Created and maintained detailed documentation of test results, deviations, and corrective actions, ensuring traceability in line with Good Manufacturing Practices (GMP).
  • Performed statistical data analysis using histograms and box plots (box-and-whisker diagrams) to detect variability and identify outliers in quality measurements.
  • Applied analysis of variance (ANOVA) to evaluate differences between production batches and ensure process consistency.
  • Performed statistical process control (SPC) using control charts and capability studies (Cp, Cpk) to monitor and maintain quality standards.
