Backend & AI Systems Engineer
Backend & AI Systems Engineer helping startups and product teams build scalable APIs, multi-tenant SaaS platforms, and production-ready AI integrations.
Over 6+ years, I’ve designed backend systems for real traffic, real tenants, and real latency constraints — not demos.
What I build:
→ High-performance REST APIs with FastAPI (Python) and Echo (Golang) → Multi-tenant SaaS backends — tenant isolation, JWT/OAuth auth, async workflows (Celery + Redis) → AI-powered systems — RAG pipelines, semantic search, LLM integrations (LangChain, OpenAI API) → Production infrastructure — PostgreSQL, Docker, CI/CD, caching, observability
Recent impact:
• Reduced API latency by 35% through Redis caching and query optimization • Designed APIs handling 10k+ daily requests with 40% faster response times via async processing
• Built document intelligence pipelines integrating LLMs for extraction and semantic analysis
• Engineered modular multi-tenant API architecture deployed with Docker + CI/CD
