⚡ I've scaled businesses from $10K to $300K in monthly revenue and systems from hundreds to hundreds of thousands of requests per minute. I've shipped enterprise microservices for clients including large enterprises - cutting infrastructure costs by 20% and improving data processing speed by 30% on systems where downtime means million-dollar SLA breaches. 99.98% uptime. Sub-200ms response times. Revenue that scales with the infrastructure. ⚡💰 Most developers write code. I engineer systems: production-grade LLM applications, autonomous AI agents, and the high-performance backends that run them without breaking under real load. Here's what I build: ✅ GenAI applications - LLM-powered chatbots, copilots, and RAG pipelines using OpenAI, Anthropic, and open-source models, grounded in your own data with vector search. ✅ AI agents & automation - multi-agent systems and intelligent workflows (LangChain, LlamaIndex, MCP) that replace manual operations with production-grade intelligence. ✅ Backend systems - scalable APIs in Python (FastAPI, Django) and Go, built distributed, high-throughput, and reliable from day one. ✅ Cloud & DevOps - Kubernetes, CI/CD, and multi-region deployments. Reliable releases, zero drama. ✅ Integrations that matter - payments, analytics, and third-party APIs, done right the first time. Whether you need a GenAI product built from scratch, an AI agent that actually works in production, or a backend that scales without falling over - that's exactly what I do.
