A compiler written in C++ that translates a custom C-style language into x86-64 assembly, assembled with NASM and linked with ld into standalone Linux ELF64 executables.

• Lexer, precedence-climbing parser producing an AST, and a stack-based code generator supporting variables, nested scopes, arithmetic, and if/elif/else control flow.
• Custom arena allocator (contiguous buffer, O(1) pointer-bump allocation, bulk free) for AST nodes, removing per-node malloc/free overhead and improving cache locality.
• Line-numbered diagnostics and scope tracking to catch syntax errors and undeclared identifiers; 5 automated unit and integration tests run on every push via GitHub Actions CI.

Backend REST APIs in FastAPI backed by PostgreSQL and Redis, serving patients across web, WhatsApp, SMS, and voice channels (via Twilio) with JWT-based authentication.

• Integrated Twilio to deliver SMS and WhatsApp messaging channels for patient communication and reminders.
• LLM-powered agentic clinical engine using LangGraph for symptom triage, drug-safety checks, prescription guidance, and follow-up question generation, with RAG retrieval via Pinecone.
• Prescription OCR, medication reminders, adherence tracking, vital logging, FDA recall monitoring, controlled-drug abuse prevention, and admin dashboards.

Trained and optimized a DenseNet201 CNN for pneumonia detection from chest X-rays, achieving 90% accuracy.

• Built a responsive web interface for X-ray upload and real-time prediction, integrating the model to support healthcare professionals in low-resource settings.
