Hi, I'm SAI NIHAL
AI Engineer | Software Engineer
Turning complex problems into real-world products. Backend & AI Engineer architecting secure microservices and deploying production-grade generative AI across cloud infrastructure with strong engineering fundamentals.
About Me
Backend & AI Engineer (Python/Java, Azure/GCP), architecting secure microservices and deploying production-grade generative AI (RAG, agentic workflows). Scaled a multi-tenant ecosystem for 100+ concurrent tenants, slashing latency by 98% via asynchronous Azure ETL pipelines; engineered distributed inference pipelines (Vertex AI) to eliminate bottlenecks for large-scale unstructured datasets.
Currently pursuing my Master's in Computer Science at Indiana University Bloomington, I combine strong academic foundations with hands-on industry experience to deliver production-grade solutions across cloud infrastructure, AI/ML, and full-stack development. Microsoft Certified: Azure AI Engineer Associate (AI-102) | Azure Fundamentals (AZ-900).
My Journey
Indiana University Bloomington
Research Assistant
Engineered an obstetric triage classification model, achieving a 94.0% Clinical Safety Accuracy and 93.5% F1 Score, by implementing a two-stage supervised fine-tuning pipeline on a Llama 3 8B model.
- Minimized hallucinated reasoning and anchored predictions to validated guidelines by developing a gated Retrieval-Augmented Generation (RAG) architecture, dynamically retrieving clinical context via vector search when similarity exceeded a 0.65 threshold.
- Streamlined model training by curating a structured dataset of 788 patient scenarios, utilizing knowledge distillation to translate deterministic decision rules into natural-language training data.
- Eliminated cloud API latency and guaranteed local patient data privacy by deploying a 4-bit quantized Small Language Model (SLM) on high-performance computing clusters using Low-Rank Adaptation (LoRA).
Infoswift Corp.
Software Engineer (AI)
Built an asynchronous serverless ETL pipeline on Azure Functions using Docker to parallelize Gemini inference at scale, eliminating analytics bottlenecks for 20,000+ files.
- Secured 100% data isolation for 100+ concurrent tenants and prevented cross-tenant leakage by engineering a multi-tenant microservice (FastAPI, Azure). Enforced tenant-scoped paths and HMAC-signed JWTs via GitHub Actions CI/CD.
- Reduced API error rates by 40% and maintained 99.9% uptime during traffic spikes by implementing distributed rate-limiting middleware (Redis, Token Bucket).
- Achieved 90% extraction accuracy for clinical data (vitals, labs), transforming unstructured reports into structured assets, by engineering a RAG evaluation framework (LangChain).
Zion Cloud Solutions (ZionAI)
AI Engineer
Minimized review latency by 30% and enhanced Q&A reasoning by deploying distributed systems on Google Vertex AI (AutoML, Docker, K8s).
- Benchmarked few-shot prompting across 50+ repositories to streamline policy analysis.
- Slashed developer initialization time by 40% by architecting a Small Language Model (SLM) scaffolding (Node.js) to automate infrastructure setup.
- Enforced data integrity for 10,000+ concurrent records by building a type-safe validation framework across PostgreSQL and Azure SQL.
Infoswift Corp.
Software Engineer (Cloud/AWS)
Accelerated feature deployment cycles by 90% by migrating manual tasks to a fully automated CI/CD pipeline using AWS CodePipeline and GitHub Actions.
- Cut cloud infrastructure costs by 20% and improved incident response time by 50% by conducting EC2 rightsizing audits.
- Automated S3 archival policies and engineered an Amazon CloudWatch monitoring suite for 15+ servers.
