Full-stack engineer · AI + web development

Custom AI systems that run inside your cloud.

I'm a full-stack software engineer building AI systems, web apps, and workflow automation for businesses that can't hand sensitive files to random SaaS tools. Your data stays in your own cloud: encrypted, audit-logged, and never used to train a model.

Eight systems you can try right now.

Real working tools, not screenshots. Run them on your own files and see the output before we ever talk.

Enter your email, get an access code, and try them your way: upload a file, snap a photo, paste text, fill a form, chat, build a mini-automation, or role-play a private company AI. Free.

Proposal Generator

No upload and no paste. Fill in a short form and get a client-ready proposal, with your pricing used exactly as typed.

Ask Your Documents

Upload a policy or handbook and have a real back-and-forth. Answers cite the source, and suggested follow-ups keep the conversation going.

Try it

Company Brain

One company knowledge base, three roles. Ask as the Owner, Manager, or Accountant: documents your role can't see never reach the AI, and you watch that enforcement happen live.

Try it
Security & compliance

Your data stays yours.

The whole reason this business exists: AI you can use on real, sensitive documents without shipping them off to someone else's platform.

Runs in your own AWS account

When I build for you, the system is deployed into your cloud, not mine and not a third party's.

Encrypted at rest and in transit

Files and data are encrypted end to end, in storage and on the wire.

Never used to train a model

Your content is never used to train any AI model, and that is backed by the cloud provider's written terms.

Auto-deletion policies

Uploads and generated data expire automatically on a retention schedule you choose.

Full audit logging

Every access and action is logged, so you can see exactly what happened and when.

Certified infrastructure

The underlying cloud environment and AI provider carry SOC 2 Type II, ISO 27001, and ISO 42001 certifications.

What I build

The systems, end to end.

One person from start to finish: I scope it, build it, and ship it into your environment.

Document intelligence pipelines

Turn contracts, invoices, and forms into structured, searchable data your team can actually use.

Workflow automations

Connect the tools you already use and remove the copy-paste busywork between them.

Private AI assistants

Chat and Q&A trained on your documents, running inside your own environment.

Custom dashboards & portals

Internal tools and client portals built around how your team actually works.

Web applications & sites

Modern, fast web apps and business sites. React and Next.js front ends on solid AWS back ends, built and shipped end to end.

About & contact

Let's build something private.
