Hi, I'm Huma Ray ↘
I build AI-powered web apps for businesses: the Next.js front end, the FastAPI backend, the database, the AI features and the deployment.
My day job is full-stack engineering on an enterprise AI platform in South Korea. It runs on the client's own servers, holds 7,000+ documents and is used by 500+ people every day. I've worked on almost every layer of it: the admin dashboard, the document pipeline, search, and deployment.
A SaaS idea, an internal tool or an existing product that needs AI added.
Next.js and TypeScript front end, FastAPI or Node backend, PostgreSQL or Supabase, login and user roles, admin dashboards, and deployment with Docker.
Chat assistants, document generation, summaries, classification and search, using OpenAI, Claude, Gemini or open-source models.
Chatbots and search that answer from your own PDF, Word, Excel and PowerPoint files and show the source of each answer.
Agents that call your APIs and tools, plus n8n workflows that connect AI to Slack, email, Google Drive and your CRM.
Data-heavy admin panels with CSV import, approval flows and live updates.
Open-source LLMs on your own GPUs or CPUs, so your data never leaves your network.
Every layer of the product, built by the same person, so nothing gets lost in a handoff.
Next.js and TypeScript front end with login, user roles and admin dashboards.
FastAPI or Node backend: REST APIs, Server-Sent Events for streaming answers, WebSockets for live updates.
PostgreSQL or Supabase for your records, with Prisma for the schema and Redis where speed matters.
Chat, summaries, classification and search with OpenAI, Claude, Gemini or open-source models. Answers from documents show their source.
Docker and Docker Compose, Nginx and CI/CD, on AWS, Linode, Vercel or your own servers.
Admin panels, document pipelines, agents, editors, live dashboards and workflows.
A Next.js admin panel for managing knowledge bases (bulk uploads, retries, live status), a FastAPI document processing service that handles PDF, Office, email and Korean HWP files with tables, and Elasticsearch search. Deployed on-premise with Docker.
An agent that turns a company's own documents into branded Word, Excel and PowerPoint reports, with sources for every claim.
A Next.js app where staff draft press releases with AI in a rich-text editor and monitor news coverage from a dashboard.
A Next.js site with API docs, searchable FAQ, changelog, bug reports and an AI chat that answers from the docs.
Live production line tracking, bottleneck alerts and line balancing for a manufacturer.
An n8n workflow that drafts replies from a knowledge base and sends low-confidence tickets to a person in Slack.
Picked per project, not out of habit.
I break the work into small milestones, so you see working software early.
Fixed price when the scope is clear, hourly when it isn't.
And I tell you early if something will take longer.
