Sound
familiar?

Where AI projects usually stall.

01

“Your team answers the same questions all day.”

Support, sales and operations spend hours on answers that already exist in your docs and systems.

02

“You tried a chatbot plugin and it made things up.”

Generic tools don’t know your business, your data or when to hand off to a person.

03

“You have a ChatGPT demo, but nothing customers can actually use.”

Getting from a prompt that works once to a reliable product is the hard part.

04

“You’re worried about where your data goes.”

You need AI that respects customer data and your existing access rules.

Production AI.
Not demos.

AI shipped inside real products used by real customers.

01

AI trip
planning

As CTO of TravelSpoken, I built AI-powered trip planning into a full-stack travel platform alongside booking, payments and integrations.

Platform technology contributed to a multi-million-dollar fundraise.

02

LLM
integrations

Production integrations with OpenAI and Gemini models, connected to real application data, user accounts and workflows.

Built into shipped software, not prototypes.

03

Production
at scale

As a senior full-stack developer on a high-traffic consumer platform, I built features, shipped deployments and maintained the live apps and production database.

2M+ sign-ups · 1.1M+ active users · 7M+ entries.

AI that does
real work.

Built around your data, your workflows and your customers.

01

Customer chatbots

Website and in-app assistants that answer from your own content and hand off to a person when needed.

02

AI agents

Agents that take action: look up orders, update records, draft replies and trigger workflows.

03

Knowledge assistants

Internal assistants (RAG) that search your documents, policies and data so your team finds answers without digging.

04

ChatGPT integration

OpenAI or Gemini built into your existing app, CRM or internal tools.

You work with
the builder.

No agency handoff. Speak directly with the developer building your product.

Christopher Walsh, senior full-stack developer in Toronto

I build the whole system around the model — data, backend, interface and deployment — so the AI holds up once real customers use it.

6 years across the full stack — mobile (iOS/Android), web, backend, cloud and AI — including deploying and maintaining production apps and databases for 1.1M+ active users. That means fewer handoffs, faster decisions and one person accountable for the result.

Clear from
day one.

Start with the business goal, define the right build, then move through launch without unnecessary complexity.

01

Strategy

Find the workflow where AI saves the most time or wins the most customers.

02

Architecture

Choose the model, data sources, guardrails and handoff rules before building.

03

Build

Test against real questions and real data, then tighten answers until they’re reliable.

04

Launch

Deploy, review real conversations and keep improving accuracy.

$5K–$25K

Typical AI chatbot and agent projects run $5K–$25K. The range depends on what the AI needs to know and what it needs to do. A focused assistant answering from your content sits at the lower end; agents that take action across several systems sit higher.

Moves it up the range

  • Agents that take actions in other systems
  • Many data sources or integrations
  • Custom admin dashboards and analytics
  • Strict privacy or compliance requirements

Keeps it lean

  • One focused use case to start
  • Content that’s already written down
  • An existing site or app to embed into
  • Standard hosted models from OpenAI or Gemini

Straight
answers.

The questions people ask before booking a call.

How long does a typical project take?

It depends on the use case and the number of systems involved. A focused assistant that answers from your existing content is a much smaller build than an agent connected to several tools. You get a timeline after the strategy call, tied to a defined first release.

How fast can we start?

Quickly. Book a strategy call and we can usually talk within a few days. If we’re a fit, you get a written scope and estimate shortly after, and work starts as soon as you approve it — no long sales process.

How do you handle data privacy with AI features?

Privacy is designed in from the start: only the data a feature needs is sent to the model, access follows your existing permissions, and providers and settings are chosen to fit your requirements. We cover this on the strategy call before anything is built.

Will the chatbot make things up?

Any AI model can be wrong, so the system is built to limit it: answers grounded in your own content, clear boundaries on what it will answer, and a handoff to a person when a question is outside those boundaries.

Do I own the code?

Yes. You own the code and the repository, and accounts are set up in your name. You are never locked in to working with me.

How do we work together day to day?

You work directly with me — no account manager and no agency handoff. You get regular progress updates, working builds to review, and quick answers when decisions come up.

What if I only need a small feature, not a full platform?

That’s fine — not every project is a full build. A single feature, an integration, a fix or a review of existing code can be scoped and quoted on its own. The strategy call is free either way, so it costs nothing to ask.

Do you sign NDAs?

Yes. I’m happy to sign your NDA before you share details — send it over before or after booking. Your idea and information are kept confidential either way.

What does something like this cost?

Typical AI chatbot and agent projects run $5K–$25K, plus the model usage costs from the AI provider. Scope, data sources and integrations are the biggest drivers. You get a clear estimate after the strategy call.
