Who I am

Anyone can demo AI. Few can keep it running in production.

I'm Hamza Qureshi, a Senior Full-Stack AI Engineer with 5 years shipping production agentic systems. As team lead at Evren AI, I architect LangGraph multi-agent platforms for US clients, from a live workplace-mediation product to a HIPAA-aware financial assistant. I turn LLMs, RAG, and real-time voice into systems people actually rely on.

Selected Work

Real systems, real users.

A closer look at the products and AI systems I've shipped.

AI Mediation Platform for Employee Relations
01

AI Mediation Platform for Employee Relations

An AI platform for workplace case resolution across conflict, raise requests, and performance reviews. I led the LangGraph agent architecture, memory system, routing logic, and question-generation flow that power structured, multi-turn conversations with reliable handoff between case types. It is live in pilot with real organizational users.

Real-Time AI Language Learning Platform
02

Real-Time AI Language Learning Platform

A real-time AI language-learning platform for German, Spanish, French, and English. I led the voice AI architecture across speech-to-text, LLM, text-to-speech, WebSocket infrastructure, and interruption handling. It hits sub-2-second end-to-end latency for a natural conversational experience, and powers quizzes, streaks, and module progression in production.

AI-Powered Financial Platform for Healthcare Providers
03

AI-Powered Financial Platform for Healthcare Providers

A HIPAA-compliant AI financial platform for healthcare providers, built on a LangGraph multi-agent architecture. I designed four specialized ReAct agents (Supervisor, Financial, Clinical, Marketing), each with dedicated toolsets and integrations like Sage, Bill.com, HubSpot, and SharePoint. Built on FastAPI, PostgreSQL, and AWS with RPA and ETL pipelines, it delivers an AI voice and chat assistant, cash-flow analytics, P&L reporting, and intelligent document search, with full RBAC, audit logging, and encrypted data handling.

FacialTrack: Facial Recognition Attendance System
04

FacialTrack: Facial Recognition Attendance System

A real-time AI attendance system using facial recognition for automated classroom monitoring. I engineered a Python backend with OpenCV and FaceNet for live face detection from webcam feeds, a PostgreSQL schema for session logs and entry/exit tracking, and RESTful APIs for a Flutter Android app with role-based access for multi-teacher, multi-subject management.

AI-Powered Sales Talent Matching Platform
05

AI-Powered Sales Talent Matching Platform

A full-stack AI hiring platform for sales recruitment that replaces traditional résumés with verified performance data. I engineered an AI sales-fit score using ML models and OpenAI across 11 metrics, built FastAPI scoring microservices on AWS, and integrated Apollo.io enrichment with a Next.js recruiter dashboard. The platform served 12,000+ users, supported 450+ placements, and cut hiring cycles by 50%.

AI Business Incubator Platform
06

AI Business Incubator Platform

An AI-powered business-validation platform that takes users from raw ideas to structured market research in one workflow. I owned the full product solo, from the frontend and backend to the database and LangChain orchestration across Perplexity and OpenAI. It handles persona creation, pain-point discovery from real web and Reddit signals, idea generation, and long-form research reports, cutting early-stage validation from weeks to minutes. Deployed on AWS.

AI Personal Operations Agent
07

AI Personal Operations Agent

A multi-agent AI assistant that automates Gmail, Google Calendar, and GitHub. I owned the full LangGraph architecture across planning, execution, semantic memory, voice input, and LangSmith tracing. It demonstrates real agentic workflows, persistent context, and production-style integrations across everyday productivity tools.

AI Platform for Healthcare Intelligence & Workflow Management
08

AI Platform for Healthcare Intelligence & Workflow Management

An AI platform for healthcare intelligence and workflow management that helps teams handle complex information, structured processes, and operational workflows. I owned the product end to end as the solo engineer, from application architecture and backend systems to data flow and the AI integration layer. It is designed for secure healthcare operations and intelligent data handling that feels practical and product-ready, not experimental.
