What I'm looking for

I’m looking to build and scale production-grade analytics and software systems—data platforms, automation, and machine learning—where performance, clean architecture, and long-term maintainability matter.

I’m a Senior Software Engineer with 20 years of experience building scalable web applications, data platforms, and cloud-based systems. I deliver production-grade solutions across healthcare, fintech, e-commerce, and logistics, with a strong emphasis on performance, clean design, and long-term maintainability.

In my current role as an IT Analytics & Reporting Consultant, I design enterprise analytics platforms for capacity planning, forecasting, and resource management, and I’ve improved resource allocation accuracy by 15% through Power BI dashboards and SQL-based datamodels. I also architect and scale internal tools, automate reporting workflows with UiPath and Power Automate, and develop forecasting and regression models using SAS and R to align projections with actual spend.
