At Daivtech, I architect and build production healthcare and enterprise systems. I work across the full stack — from designing LangGraph AI agents and RAG pipelines on AWS Bedrock to building secure REST APIs and owning cloud infrastructure end-to-end.

• Architected the SendScript Healthcare EMR platform end-to-end on Next.js, TypeScript, PostgreSQL, and AWS, supporting a clinical team of ~40 staff across intake, diagnostics, and reporting workflows in production.
• Designed a LangGraph StateGraph agent to orchestrate multi-step reasoning over radiology documents, cutting average review time from ~25 minutes to ~10 minutes per case.
• Built a RAG pipeline on AWS Bedrock using Claude models with Titan Embeddings and hybrid k-NN + BM25 retrieval, improving answer relevance on ~200 clinical queries.
• Implemented LLM safety guardrails — semantic caching, hallucination verification, prompt-injection protection, and PII filtering — cutting duplicate LLM calls by ~30% during peak usage.
• Designed the core REST API layer with PostgreSQL, JWT Authentication, and RBAC, covering ~20 endpoints governing clinical data access.
• Owned AWS infrastructure (EC2, VPC, IAM, RDS, encrypted storage) and built CI/CD with Docker, GitHub Actions, Nginx, and PM2, reducing release time from ~2 hours to ~15 minutes.

At iamneo, I built full-stack educational platforms serving thousands of concurrent users. I led infrastructure migrations, built serverless backends, and strengthened platform security for high-stakes online examinations.

• Built full-stack educational platforms using Angular, Node.js, TypeScript, and REST APIs, supporting ~800 concurrent users during peak exam windows.
• Led migration of compiler infrastructure from GCP to Azure VM Scale Sets, redesigning autoscaling to handle ~90 concurrent compile jobs.
• Built serverless backend services with Google Cloud Functions and Cloud Scheduler, and load-tested with K6 to validate scalability under ~90 concurrent users.
• Integrated Zoom Video SDK for secure online examinations and remote proctoring for ~4,000 students across multiple institutions.
• Migrated enterprise applications from Angular 7 to Angular 15 with zero breaking changes, and built GitHub Actions/Docker CI/CD pipelines cutting deployment time from ~1 hour to ~20 minutes.
• Strengthened frontend security with DevTools detection and client-side hardening, reducing tampering attempts from ~15/week to under 5.
