What I'm looking for

I’m looking to build and scale low-latency, production-grade backend systems for AI SaaS—optimizing APIs, asynchronous workflows, and LLM RAG pipelines, while partnering cross-functionally to ship resilient cloud infrastructure with measurable performance improvements.

I’m a Senior Backend Engineer focused on designing and engineering high-load AI SaaS platforms and the core database infrastructure that keeps them fast and reliable.

In my current role, I engineer scalable backend infrastructure for high-traffic AI SaaS while stabilizing complex cloud architectures, aiming for sub-100ms latency. I optimize core APIs to slash response times, and I scale asynchronous data workflows for production-level throughput.

I also architect LLM orchestration workflows and RAG pipelines using LangChain and OpenAI to deliver intelligent text and voice features. From containerized deployments with Docker and Kubernetes to automated GitHub Actions CI/CD, I build resilient backend logic for fast-paced environments.

Earlier, I built and optimized high-throughput RESTful APIs with Django and FastAPI, structuring database layers with PostgreSQL and Redis and using Celery to isolate heavy computation. I’ve scaled systems for concurrent user loads, integrated secure multi-tenant access with JWT/OAuth2, and supported data workflows using Scrapy and Playwright for automation and large-scale processing.
