I build backend systems in Go for teams that need them correct under real load, not just working in a demo. Most of my work is the high-stakes part of a backend: payment and wallet flows, double-entry ledgers, real time systems, and event driven pipelines. The kind of work where a race condition or a double-processed message isn't a cosmetic bug, it's money moving twice. Getting that right, and keeping it right as the system grows, is what I do. Where I help most: - High-throughput Go services that stay correct and fast under load - Payment, wallet, and ledger systems where the numbers have to reconcile exactly - Event-driven pipelines with Kafka or RabbitMQ - Real-time systems over WebSocket - Cloud infrastructure on AWS and GCP with Docker and Kubernetes - Diagnosing performance and reliability problems in systems that already exist Go is my primary language. I also work in TypeScript with NestJS and Next.js when a project needs the full stack, and Python where it fits. I do my best work when I'm involved early, while the architecture and data model are still open. If something is already built and struggling I can help there too, though I'll usually want to fix the cause rather than patch around it. I document what I build so your team can maintain it after I'm gone, and I'll tell you when I think something is a bad idea. Tell me what you're building and I'll let you know if I'm a good fit.
