What I'm looking for

I'm looking for a fully remote backend role where I can own a solution end to end. My main focus is Python and FastAPI, though I'm open to ASP.NET Core given my enterprise background, and comfortable with React on the frontend.

I've delivered two production ASP.NET Core microservices at E.ON (Delgaz Grid) as part of a 30K+ LOC monolith migration, building backend APIs and Angular components while maintaining live enterprise systems.

I improved vendor issue resolution by about 70% through SOAP/WSDL integration analysis, and reduced core database query execution time by about 80% by identifying and resolving missing indexes. I also maintain SQL Server and PostgreSQL procedures across four systems and administer access for more than 500 accounts.

Python has been part of my background since university, and more recently I've taken it to a production level. Independently, I built a full-stack warehouse operations service with FastAPI, PostgreSQL, React, JWT authentication, three-role RBAC, row-level locking, automated integration tests, and CI/CD deployment.

My work spans API design, database modeling, concurrency control, enterprise integrations, testing, Docker, and cloud deployment. I also bring experience evaluating AI-generated content for quality, accuracy, relevance, localization, and user intent.

Right now, I'm looking for a fully remote backend role, ideally Python and FastAPI, where I can own a solution end to end.
