Message

As an Independent Software Engineer, I build backend services and microservice-based applications with Go, Python, and FastAPI, from architecture and integrations through production deployment on AWS. My client work includes healthcare and banking applications with authentication, TLS encryption, and audit logging.

At Effer Ventures, I shipped features for a production platform serving 50,000+ users and cut database load by about 65% with Redis caching and distributed rate limiting. I also built event-driven webhook processing and idempotent background workers with retry and failure handling.

At Smartdings GmbH, I built and maintained AWS infrastructure with AWS CDK and administered Azure DevOps CI/CD pipelines. I also monitored production systems with CloudWatch and added Pytest automation to reduce recurring issues. On NudgePe, I built and deployed a SaaS platform for invoice reminders and payment recovery.
