Message

At Publicis Groupe, I architect reusable .NET ingestion frameworks and develop services that process advertising data from platforms including Meta Ads, TikTok Ads, Twitter/X Ads, and Walmart Connect. I built configurable modules and reusable libraries to support validation, orchestration, parsing, and data transformation.

I also developed FastAPI services and ETL jobs for data validation and processing, and optimized Amazon Redshift loads. I supported a migration from Amazon Redshift to Databricks, converting SQL logic to Spark SQL and designing Delta Lake tables.

At Accenture, I worked on the Rebar Messaging project, migrating legacy applications from .NET to .NET Core. I also developed cloud workflows and supported testing and deployment work across client projects.

Earlier at Accenture, I developed ASP.NET Core and ReactJS features for an e-commerce application, designed its SQL Server database architecture, and automated billing-file verification. I hold Microsoft Certified Azure Fundamentals: AZ-900 and a .NET Developer certification earned during training at Accenture.
