Efehan T.

I build scalable systems, APIs, and cloud infrastructure, and I help teams integrate AI into real products without over-complicating their stack. If you need a senior engineer with enterprise grade experience in real world scenarios where the actual expertise matters — I can help. --- What I do • Build high-performance microservices with Go • Design distributed, event-driven systems (Kafka, async architectures) • Develop AI-powered features (agents, RAG pipelines, LLM integrations) • Design and automate AWS and Azure infrastructure using Terraform • Refactor and improve existing systems --- How I work I focus on systems that are: • Scalable and stable under real load • Easy to maintain and extend • Production-ready from the start I’ve worked with startups and growing teams where backend reliability directly impacts the business. I take ownership of the system, not just individual tasks. --- Tech I work with Go, .NET, Python, AWS, Azure, Kubernetes, Kafka, Terraform, gRPC, Linux, React, Angular AI: LLM integrations, RAG, AI agents, automation workflows --- Why clients work with me • Strong in both backend engineering and infrastructure • Can design systems, not just implement features • Communicate clearly and work independently • Focus on long-term maintainability over quick fixes --- If you need someone to build or scale your backend, design distributed systems, or integrate AI into your product in a clean and reliable way, feel free to reach out.
