Data Engineering & Validation Specialist | Precision Data Hub

Feb 2022 - May 2023 • 1 yr 3 mos

As a technical consultant, I focused on the "Accuracy-First" management and validation of large-scale data sets for medical practices and regional SMEs. I specialized in "Data Normalization," creating custom Excel macros, SQL queries, and Python scripts to validate thousands of patient and customer records against strict regulatory and privacy standards. My role involved the automated generation of "Compliance and Error Reports" that identified missing or malformed data points in real-time, allowing for immediate correction. I handled the technical side of "CRM Field Mapping," ensuring that legacy data from physical paper forms was accurately digitized and categorized into modern medical CRM ecosystems. My work required a deep understanding of data privacy laws and encrypted storage protocols, ensuring that all sensitive information was handled according to industry standards. I provided "System Health" monitoring for data entry pipelines, ensuring that software updates or manual errors didn't disrupt the flow of information. My goal was to make data management a high-speed, invisible part of the business workflow—a machine that processes, validates, and organizes information with zero manual intervention.

Advanced Technical SEO & Machine Readability Lead | Data Rank

Feb 2022 - Mar 2023 • 1 yr 1 mo

I focused on the technical "Middle-Ware" of website indexing—optimizing site structures for the earliest versions of machine-learning-based search crawlers. My role involved the technical setup of advanced JSON-LD structured data and canonical link logic to prevent duplicate content errors and crawl budget waste. I utilized custom Webhooks and API pings to create "Real-Time Indexing" triggers that notified Google and Bing the moment content was updated or products were added. I am highly proficient in "Server-Side Optimization," where I used Nginx and LiteSpeed configurations to ensure that technical site speed was maximized for bot readability. I managed the deployment of automated site-map generators and broken-link monitors that provided real-time visibility into the "Indexability" of large enterprise domains. My work required a deep understanding of bot behavior and crawl patterns, ensuring that the site's most important pages were prioritized by search engines. I provided business owners with a "Technical SEO Roadmap" that included competitive gap analysis and automated keyword tracking. My goal was to make the website’s information foundation as "readable" as possible for the machines that determine search rankings.
