What I'm looking for

I want a Web Developer role where I can apply Python automation, system integration, and data-validation skills to improve backend processes and data integrity, with opportunities for growth and collaborative, impact-driven work.

I am a proactive junior software engineer with two years of experience building automation and data validation tools that improved dataset accuracy and shortened review cycles. I have engineered preprocessing scripts, API integrations, and debugging utilities to support large-scale annotated datasets and boost cross-team productivity.

I've worked with SQL and NoSQL databases, developed predictive analytics using Teradata, and hold a strong foundation in data science and mathematics. I seek opportunities to apply my Python and system-integration skills to optimize backend processes and improve data integrity in web development projects.
