I build full-stack web applications, APIs, data pipelines, and reporting solutions.

I've built employee portal functionality for AT&T's Compass application, helping managers view technician vehicle information, performance, and reports.

As a Software Engineer at AT&T, I developed full-stack features with Angular, Python FastAPI, Node.js, SQL Server, HTML, CSS, Bootstrap, and TypeScript. I implemented routing, lazy loading, API requests, JSON validation, code reviews, and Agile sprint delivery.

At Educational Measures, I supported Edtrak survey and reporting applications using PHP, Angular, Node.js, MySQL, Linux, and REST APIs. I also wrote PHPUnit tests, shell scripts, complex database queries, procedures, functions, triggers, and views.

I've built Tableau dashboards and ETL pipelines with Airflow and Snowflake, including Snowpipe ingestion from AWS S3, Streams, Tasks, Time Travel, and reusable data logic. I focus on completing quality work on time, regardless of the technology involved.
