Available for freelance & engineering roles
Need an engineer who can ship the backend and AI layer?
I’m Lakshmi Udbhav Regadamilli, a backend-focused Full Stack AI Engineer. I build production-oriented APIs, RAG systems, LLM integrations, cloud workloads, and full-stack AI features for startups and product teams.
AI systems
RAG, document pipelines, embeddings, vector retrieval, LLM integrations, structured outputs, semantic caching and AI automation.
Cloud & scale
AWS Lambda, EC2, S3, Step Functions, CloudWatch, Docker, distributed systems, microservices and event-driven architecture.
Why this portfolio is useful for hiring
- Real engineering work is separated from generic skill lists through projects and case studies.
- Technical decisions are documented through articles on RAG, FastAPI, LLM cost optimization and retrieval quality.
- Performance claims are explicitly labeled as author-attributed rather than presented as audited benchmarks.
- GitHub repositories provide implementation evidence while the portfolio explains the engineering context.
