I help companies build and evolve reliable backend systems, integrations, and automation workflows. I work in two modes depending on what the client needs: - as an independent engineer delivering a scoped backend project end-to-end - as a senior embedded engineer augmenting an existing team on a long-term hourly contract I have 15+ years of hands-on experience in Java/Kotlin backend engineering across enterprise platforms, internal systems, and automation-heavy workflows. My work includes backend services for compliance, fee processing, reporting, custom business workflows, and third-party integrations. In one long-term enterprise engagement, I built and evolved services that reduced manual operations by 65–85%, supported worker-classification workflows, and included ownership of 8+ production microservices. I can help with: - Java/Kotlin backend development with Spring Boot, Dropwizard, and Quarkus - REST/gRPC APIs and third-party integrations, including Salesforce - Microservices, RBAC, multi-tenancy, service decomposition, and production support - PostgreSQL, MongoDB, AWS/Azure, Docker, Kubernetes - CI/CD with GitHub Actions and Jenkins - Observability with OpenTelemetry and Grafana I also have practical experience with AI/LLM-based automation for document and data workflows: - LLM-powered classification, extraction, and workflow automation - OpenAI API / local LLM integrations - backend services and tooling for processing documents, structured data, and internal knowledge workflows I’m most useful when you need a senior engineer who can understand complex business logic, translate it into maintainable backend services, and deliver reliably with minimal hand-holding.
