Harpreet Singh

I'm a Software Engineer with 3 years of experience building scalable web applications across frontend and backend, currently at Carelon (a subsidiary Elevance Health). I work full-stack on a specialty pharmacy platform used by patients, prescribers, and healthcare teams, contributing across React/Next.js frontend, Node.js/Express.js backend services, and .NET Core APIs.

I focus on measurable impact through AI and performance in real products. I developed an AI Intake Automation module that auto-extracts fields from fax and prescription PDFs, reducing manual intake effort by 80% and built an AI-powered document intelligence chatbot using a RAG pipeline and OpenAI API, cutting manual lookup time by 30% for pharmacy teams.
I also built a custom Jira MCP Server in TypeScript adopted by 40+ engineers, QAs and leads across multiple teams, which sits at the intersection of developer tooling and AI workflows.

On the product side, I delivered a Provider Portal in Next.js from scratch — engineering data-heavy AG-Grid tables with server-side pagination and GraphQL, improved lead performance by 30%.
Implemented frontend observability using OpenTelemetry, achieving 99.9% uptime and faster incident resolution. I've received 5 Impact Awards at Carelon for high-impact contributions across multiple quarters.

Outside work, I build and ship my own products — SerialTrack (an OCR-powered warranty tracker that cuts data entry from 5 minutes to 10 seconds) and Guru Nanak Electricals (a spare parts e-commerce platform with AI semantic search using vector embeddings).

I'm actively looking for Frontend or Full Stack AI SDE-II roles at product-based companies, startups, and MNCs where I can continue building at the intersection of modern frontend and applied AI.
