---

For the last decade of my career at Chevron, I have focused on Microsoft-based solutions that included:

• .Net: C#, VB.Net, ASP.Net, MVC, LINQ, …
• Azure: DevOps, Ansible, CI/CD pipelines, Data Factory, …
• SQL: on-prem and Azure, complex T-SQL, stored procedures, ETL, SSIS, …
• Power Platform: PowerApps, Power Query, Power Automate, …

I also used various web-standards like HTML5, CSS3, JavaScript, TypeScript, CSS preprocessors (SASS) and various UI frameworks like jQuery and Angular with Material Design.

Major contributions:

• Reduced data loading times by at least 90% by creating a parallel processing model in Power Automate (PowerApps Flows).
• Reduced processing times by 50% (saving 2-4 hours per runtime) by optimizing data analytics reports (stored procedure T-SQL script).
• Reduced API calls by 90% with caching, production deployment downtime by over 99% (from minutes to under 5 seconds), and manual process by 100% with automated deployment using PowerShell; enabled scalability; and improved UI/UX by rewriting a payment app named GO-1627 using ASP.Net MVC (with Razor) and jQuery with custom JavaScript framework.
• Eliminated up to 100% of the manual process by introducing and training non-technical business users on Microsoft Power Automate for Desktop: enabling their departments to maintain, extend, and encourage development of new automations.
• Designed UI/UX and coding standards for new modern projects using Angular and TypeScript.
• Mentored interns who became employees and trained business analysts moving to technical roles on Microsoft PowerApps (canvas apps and flows) and Power Automate to support existing and develop new low-code apps and automations in their groups or departments.

My last role as a Technical Lead had responsibilities that included having to:

• Lead a team of five (5) developers in developing a modern inventory and accounting app, CCIAM.
• Contribute to resolving technical debt and continuous improvement of development processes using Agile methodologies.
• Collaborate with cross-functional teams to gather requirements and design solutions that meet business needs.
• Document technical specifications, implementation details, integration features, configurations, and best practices, ensuring clarity and accessibility for stakeholders.
• Demonstrate technical leadership through design and code reviews, and best practices.
• Mentor, train, and promote knowledge-sharing culture.
