Hi. I'm Sean Erfan.

I am working as a Software Developer at Lotus MD. Previously, I was a Full Stack Software Engineer at North Atlantic Industries. I recently graduated from Stony Brook University with a double major in Computer Science and Applied Mathematics & Statistics. I co-founded the Artificial Intelligence Community and served as President for 2 years. I won prizes in 4 hackathons, most recently my company's internal hackathon and HackHarvard 2024. Some of my previous involvements included being the Secretary of the Stony Brook Computing Society.

Software Developer @ Lotus MD

Software Engineer @ North Atlantic Industries

Wave Picking App

A native Android app (Java, MVVM, Zebra DataWedge) used daily by warehouse workers to fulfill 20+ production orders simultaneously. Features an offline-first sync architecture with a local queue to cache failed requests and reconcile inventory on reconnection — zero data loss during network instability. Backed by an ASP.NET Core/SQL Server API using Serializable transaction isolation to eliminate race conditions and automatic session forking to preserve user progress during concurrent picks.

Kit Management Dashboard

A full-stack Angular/ASP.NET production planning dashboard that won honorable mention at the company hackathon and was extended to production, saving 6 hours weekly across the operations team. Backed by a complex SQL view aggregating real-time BOM shortages, purchase orders, and batch schedules to calculate build feasibility across thousands of components.

AI, ETL & Cloud Systems

Built an AI-powered DVT generation service (Python FastAPI + Gemini Pro) that ingests PDF specs and produces formatted DOCX reports, deployed on AWS ECS/Fargate with CI/CD via Jenkins. Orchestrated a fault-tolerant ETL pipeline syncing RoHS/REACH compliance data for 15,000+ components. Designed a certification management system for 75 employees using AWS S3 pre-signed URLs with automated email reminders, and provisioned ephemeral dev environments via Terraform and CloudFront.

Co-Founder, AI Community @ SBU

Co-founded Stony Brook's AI club, serving as VP for 1 year and President for 2. Led an e-board of 10, hosted ML workshops and competitions, organized guest speaker events, and grew the club to official CEAS recognition with a datathon of 50+ competitors.

Hackathons & Research

Won prizes at four hackathons: Hopperhacks 2024 (AI Track), SBUHacks 2024 (Best MongoDB Atlas), HackHarvard 2024 (AllHealth Track), and NAI Company Hackathon (Honorable Mention).
