Design and engineering, from the same desk.
I have worked hands-on as an IT engineer for more than 20 years. Today I design and build websites and web apps on my own, from the first layout to the backend, automations and deployment. Most of the visual design in my portfolio is mine, so the person shaping an idea is usually the one shipping it.
A product decision
Boat, dates and quote in one workflow
San Blas On Board / Product design & development
San Blas On Board is a private prototype I designed and developed for a charter booking team. The catalog, the availability calendar and the trip quotation could have been three separate tools. I treated them as one path instead: choose a boat, check its dates, then price the trip.

The boat is the starting point: capacity, rates and availability belong to the same choice.
How I work
See AI activityDefine the product
I turn the brief into a useful first release: who it serves, the main journey, the data it needs and what can wait. Open questions become explicit decisions.
Scope · Flows · Data & statesSet the visual direction
I shape hierarchy, typography, spacing and density around the audience. I usually design what I build; when a client supplies Figma, as with 3rdmil, I preserve that direction.
Layout · Type · Mobile behaviorDirect the build
I give Cursor and Codex focused tasks, inspect the changes and refine the result. Product and design decisions stay with me, including when an agent's first answer is not good enough.
Working code · Reviewed iterationsTest the actual journey
I check the important flows, responsive layouts, keyboard access and failure states. I review screenshots as well as code, then correct what does not hold up in use.
Functional checks · Visual QALeave a usable handoff
The next person needs to be able to run the project and understand it. I document setup, configuration, key decisions and known limitations alongside the source.
Runnable source · Setup · Handoff notes
What a documented handoff includes
Run it
Source code, setup commands, environment-variable requirements and deployment notes. Credentials stay outside the repository.
Understand it
Scope, key product decisions, dependencies and the boundaries of the current release.
Continue it
Verification notes, known limitations and a practical starting point for the next iteration.
For review-led engagements, we can also agree on active-time logs excluding breaks and an export of the agent conversation, with credentials and client data removed.
