Senior AI/LLM Backend Engineer | 15+ Years in Java, Python, RAG & Scalable Backend Systems
I am a Senior AI/LLM Backend Engineer with 15+ years of experience building scalable backend systems, AI-powered workflows, RAG pipelines, semantic search platforms, recommendation systems, and production-ready microservices. I specialize in Java Spring Boot, Python, FastAPI, LangChain, LlamaIndex, PostgreSQL, Redis, vector search, and cloud-native architecture.
I help businesses turn complex data, documents, and workflows into reliable AI-enabled products. My experience includes building LLM enrichment services, hybrid retrieval systems, structured output validation, async processing workers, ecommerce discovery platforms, finance/telecom microservices, and high-availability backend APIs.
I focus on clean architecture, performance, reliability, observability, cost optimization, and practical business impact.
Work Terms
I am available for remote work and flexible with client time zones. I prefer clear project scope, milestone-based delivery, and regular communication through Guru, email, Slack, or video calls when needed. For hourly projects, I provide transparent progress updates and track time carefully. For fixed-price projects, I prefer agreed milestones with escrow funding before work begins.
My working style is professional, responsive, and detail-oriented. I focus on clear requirements, clean architecture, reliable delivery, documentation, and long-term maintainability. I am comfortable working independently or collaborating with product, backend, AI, data, and DevOps teams.
