I build systemsthat earn theircomplexity.
Product-minded engineering across AI, data, security, and native software. From the first question to the details that make it work.

Selected work / 01—04
Ideas, put into practice.
Four projects across learning, exploration, native software, and safer links. The decisions matter as much as the interface.
Product system
A multi-role online academy connecting curriculum, teaching, practice, progress, reporting, and operations.
Project notes
- One connected learning journey.Purpose-built student, teacher, parent, and administrator dashboards keep lessons, assignments, and progress connected.
- AI with teacher oversight.AI chat and quiz generation support teaching while keeping assessment review in the teacher's hands.
- Progress families can follow.Parent dashboards and downloadable PDF reports make learning progress easier to understand and share.
Web experience
An interactive globe that connects country discovery with decades of live macroeconomic context.
Project notes
- Explore through geography.An interactive 3D globe connects country discovery with searchable profiles and detailed country information.
- Put numbers in context.Historical World Bank charts reveal how a country's economic indicators change over time.
- Built for different screens.Mobile-friendly detail panels preserve the globe-led exploration experience on smaller devices.
Native app
A lightweight native Markdown reader that treats editing as a supporting mode, not the opening screen.
Project notes
- Reading comes first.Markdown opens as a finished, typeset document, with editing available when you need it.
- Edit with the result in view.Split manuscript and synchronized preview modes connect your writing to its rendered appearance.
- A native Windows workflow.File associations, native dialogs, and keyboard shortcuts make working with local documents straightforward.
Security tool
A URL shortener and universal redirect expander that reveals where links lead before users open them.
Project notes
- See the destination before opening it.Inspect up to ten redirect hops without loading the destination page.
- Share links on your terms.Account controls include custom aliases, expiration dates, passwords, and one-time links.
- Useful insights, less personal data.Link history and click analytics work without storing raw IP addresses.
The practice
The interface is just the beginning.
I’m an independent full-stack engineer who likes making the pieces fit: the product, the data, the logic, and the experience.
The real work is making the system underneath coherent, testable, and honest about its limits. That’s the thread running through everything here.
Build with care. Show the reasoning.
Product systems
End-to-end journeys, domain models, and the state that connects them.
Applied AI
Useful workflows, evaluation, and places for human judgment.
Security & privacy
Local-first processing, clear boundaries, and careful defaults.
Data & native
Analytical notebooks, desktop tools, and cross-device protocols.
The wider picture
Small tools. Bigger explorations.
More products, tools, and research to explore. Open a collection to look around.
