No fault of Alan's, the work we were looking for was different than what the job post stated.

Software Project Manager with programming experience
Great guy with a lot of Project Management and Software experience.
Alan helped to document and visualize our project. He really helped us to look at it from a distance and give the right visual presentations.
I can not recommend him enough and will surely hire him again for our next project

About Alan
Rapid Prototyping Specialist | AI-Assisted Development
Columbia, United States - 1:48 am local time
WHY WORK WITH ME:
✓ 30+ years in software development and project management (PMP certified)
✓ Managed 70+ projects at EMC, Boeing, Los Alamos, Dell, and startups

✓ Built and led high-performing teams throughout career
✓ Ran successful iPhone app agency for 12 years (2008-2020)
✓ Based in Brazil, serving US/global clients since 2008
WHAT I DELIVER:
Working prototypes, not just mockups. Functional demos you can click through, test with users, and show investors. Fast validation of your concept before committing to full development.
RECENT WORK (2026, all live — see Portfolio section below for links and screenshots):
🌍 Tourist guide app
Interactive maps, location filtering, mobile-responsive, three languages
🎥 AI decision-support tool (see the demo video in my Portfolio)
Describe a decision in plain English — AI builds the alternatives out,
calculates expected value, and recalculates live when you edit a number
🤝 Two-sided expert marketplace
Clients post paid briefs, experts apply free, Stripe payments end-to-end —
built and running real transactions
🏖️ Real-estate scoring tool
Google Places data + a weighted scoring model, mapped against 30 real
properties, bilingual (PT/EN)
🧪 Interactive periodic table
Click any element to explore its nuclides — data-dense scientific UI,
shows range beyond typical SaaS/consumer work
WHO I HELP:
• SaaS founders testing new feature ideas
• Product teams validating UX concepts before dev investment
• Enterprises evaluating technical feasibility
• Startups needing investor demos quickly
• Anyone who needs to see and feel an idea before building it for real
MY APPROACH:
Semi-retired and selectively taking on interesting projects. I'm not looking for volume - I'm looking for interesting problems that can benefit from rapid prototyping. If you need ongoing maintenance or long-term development, I'm probably not your person. But if you need to validate an idea quickly, let's talk.
AVAILABILITY:
Based in Ilhéus, Brazil. Available for US business hours when needed. Selective about projects - I only take work that's interesting and well-suited to rapid prototyping.
