Backend and DevOps engineer (Go) building production systems that have to stay correct under retries, load, and multi-tenant isolation. 5 years in, Top Rated Plus on Upwork.

What I work on:
• Payment and webhook pipelines: idempotent settlement, double-entry ledgers, reconciliation
• Go microservices and APIs (gRPC, REST, WebSockets) on PostgreSQL, Redis, and Kafka
• Multi-tenant auth: OAuth 2.0, OIDC, SAML, SCIM
• Infrastructure: Docker, Kubernetes, Nomad, Terraform, AWS, Vault, Consul, CI/CD
• AI infrastructure: an MCP server platform, a Temporal-based coding pipeline, and a control plane for inference on community GPUs

Previously, I built ride-hailing billing and payouts, Go services for a social commerce platform (chat, deep links, analytics), and ERP modules. I contribute to open-source projects and maintain my own Go libraries and tools.
