Message

At EarnIn, I develop Go and Python backend services for a SaaS expense management platform within a new payroll product. I’m also modernizing legacy C#/.NET Payroll services toward cloud-native microservices on AWS.

At Charger Logistics, I designed event-driven microservices with C#/.NET Core, Confluent Kafka, and Azure, and led modernization of legacy applications and persistence layers. I also architected REST APIs for third-party integrations.

Across roles including TeamStation AI, Definity First, and Genomi-k, I’ve developed backend systems, APIs, and cloud services for real estate, enterprise, and financial products. My work has included search infrastructure, database modernization, and migrations to AWS Lambda.
