I build web and mobile products, from the first idea to a working system people use every day. I've done this for six years, for companies in healthcare, security, real estate, education, e-commerce and marketing.

I turn a business idea into a clear plan a developer or a team can start on: what to build first, what it will need, where the risks are, and what can wait. You get something concrete to estimate, budget and decide on.
I can build the whole thing myself: the website or app your customers see, the system behind it, and the setup that keeps it running. One person means fewer handoffs, fewer meetings, and a faster first version.
Chatbots, content analysis, AI search features, automated workflows. I build AI features that run reliably for real customers, not demos that work once. I currently work on a product that compares answers from ChatGPT, Claude, Gemini and Perplexity.
AI services charge for every request, and the bill grows with your users. I find where the money goes and reduce it: cheaper AI models for simple tasks, reuse of answers instead of paying twice, and tracking cost per feature so nothing grows unnoticed.
Tools like Lovable, Bolt or Cursor are great for proving an idea. But before real customers and real data, a prototype usually needs proper security, logins, testing, and hosting that won't break under load. I keep what works and rebuild what doesn't, so you don't start over.
I plan systems so that ten times more users doesn't mean rewriting everything. That covers how the parts fit together and where everything is hosted (Amazon, Microsoft or Google cloud).
I can build the core of the product myself, then lead the developers who continue it. I've led a team of four engineers and interviewed candidates for a client project.
Launch is the start. I've supported most of my projects for months after release: fixing issues, updating, adding features, and keeping the product understandable for whoever works on it next.
Reports, charts and dashboards that update live. I've built printed medical reports full of charts and real-time monitoring screens for patient and hardware data.
A few years ago, a new product needed a team of several developers and many months. Today one experienced engineer working with AI tools can cover much of that. AI handles the routine work. I make the decisions, check the result, and take responsibility for what goes live. You pay for experience, not for headcount.
You describe the problem; I ask questions.
What I'd build, in what order, and what it would take.
You see progress regularly, not only at the end.
