What I'm looking for

I seek roles modernizing legacy automation into scalable Python/SQL solutions, collaborating with stakeholders, and delivering tested, production-ready reporting. Create and maintain ETL pipelines to ensure data is in a usable format for end users.

I am a senior-level developer specializing in VBA, SQL and Python, with deep experience troubleshooting, maintaining and modernizing legacy Office-based automation into efficient, production-ready scripts. I analyze, design and reverse-engineer complex MS Access and Excel applications to deliver reliable automation and reporting.

My work focuses on converting VBA to Python and SQL, optimizing data pipelines, and ensuring data integrity through rigorous testing and validation. I have delivered production deployments using pandas, xlwings, numpy and SQLAlchemy alongside Teradata, SQL Server and MySQL.

I have led full SDLC efforts—gathering requirements from stakeholders, developing solutions, automating workflows, and documenting technical and training materials. Key achievements include automating KPI and revenue reports, streamlining data cleansing on large datasets, and reducing manual runtimes via scheduled automation.

I collaborate closely with business users, quantitative teams and operations to ensure tools meet business needs, and I use Agile practices, Jira and version control to deliver timely, maintainable solutions that improve efficiency and reporting accuracy.
