What I'm looking for

I'm looking to build scalable Python services and secure cloud infrastructure, contribute to architecture decisions, improve engineering processes, and collaborate with distributed teams.

At IntellectEU, I design and maintain RESTful APIs, scaffold services from OpenAPI/Swagger specifications, and maintain test coverage, validation, and mock data.

I manage Terraform and Terragrunt infrastructure across environments, including Lambda automation for ECS and RDS resources. I also run AWS CodePipeline and CodeBuild workflows and administer MongoDB on AWS EC2, resolving performance incidents.

Previously at Simporter, I built high-performance APIs from scratch and contributed to critical architecture decisions. I reduced a key workflow from three minutes to five seconds, mentored junior developers, and helped deploy machine learning models into production APIs.

My earlier project-management work at Uvoteam included building a department to 30 people and reaching $20,000 in monthly recurring revenue. I bring hands-on engineering, infrastructure, process improvement, and experience working with distributed multicultural teams.
