Problems I solve

Five things that cost small businesses money, starting with the one that can cost the most. Here’s how I fix them.

Services

  1. 01

    AI App Security Reviews

    You built the app with AI and it works. What nobody has checked is whether a stranger can read your customers’ data, get past the paywall, or run up your OpenAI bill. A review has a fixed scope and a fixed price, and you get it back in one week. I run an automated scan with llm-audit, then read the code by hand to catch what a scanner misses. You get every finding written up with a prompt you can paste into your AI tool to fix it, plus a call where I walk you through all of it.

    AI Integrations

    If your staff spends half the day answering the same five questions, or you’re bleeding money to no shows, automate it. I build bilingual chatbots and WhatsApp flows that take bookings, answer FAQs, capture leads, and chase follow-ups, in whatever language the customer texted in.

  3. 03

    Web & Ecommerce

    Your site is slow, looks like a template, or loses customers at checkout. Usually all three at once. I rebuild it so pages load fast on a phone and the checkout doesn’t leak buyers.

  4. 04

    Bilingual & Multilingual Sites

    Half your customers speak Spanish and your site is English-only. That is money walking out the door. I build sites in English, Spanish, and German where each language reads like it was written there, because it was.

  5. 05

    Custom Business Applications

    You run the business on spreadsheets, email, and three SaaS tools that don’t talk to each other. I replace the stack with one piece of software built around how you actually work. A dashboard, a portal, a marketplace, or an internal tool nobody outside the office will ever see.

Process

How I work

  1. 01

    Discovery

    A call. What the business does, who buys from it, and what this thing has to accomplish.

  2. 02

    Design & planning

    Wireframes and architecture, plus a scope and a date. You approve both before I write code.

  3. 03

    Build

    I build it on a real URL you can open any time. Feedback goes in as we go, not in one pile at the end.

  4. 04

    Launch & support

    Deploy, hand over the keys, walk your team through running it. I stay on for maintenance if you want me on.
