I help companies design and ship backend systems that perform under real production load. My focus is on reliability, security, performance, and long-term maintainability across business-critical services. I build and optimize REST, GraphQL, and gRPC APIs, asynchronous service architectures, and high-throughput data pipelines. I work across Rust, Python, and TypeScript with strong hands-on experience in PostgreSQL, Redis, Docker, cloud deployment, and observability tooling. For enterprise and growth-stage teams, I prioritize clear service boundaries, stable API contracts, disciplined CI/CD, and operational transparency. I design systems with auditability, fault tolerance, and extensibility from day one, so teams can scale without accumulating hidden technical debt. I also deliver AI features where they create measurable business value, including LLM integrations, retrieval pipelines, and agent-assisted workflows. My approach is engineering-first: controlled behavior, traceable outputs, fallback handling, and production-safe architecture. Clients work with me for clear communication, realistic planning, and consistent execution. I take ownership from architecture through deployment and post-launch optimization, and I align technical decisions with business outcomes. If you need a senior engineer who combines backend rigor with practical AI delivery, I am ready to help. less -
