Hello, I'm Willy. I build the next useful thing.
I'm a full stack software engineer turning ambitious ideas into dependable web platforms, mobile apps, and intelligent AI products.
Selected work
Project gallery
A cross-section of problems I enjoy solving. Open any project to try its live demo.
Commerce Platform
A fast, resilient storefront architecture built for conversion and continuous delivery — catalog, cart, and checkout that stay snappy under real traffic.
Operations Console
A real-time control center turning complex operational data into clear decisions — live metrics, alerts, and workflows in one screen.
Everyday Fitness
A cross-platform training experience with offline-first data and seamless sync — workouts land on every device, even from the gym basement.
Field Companion
A focused mobile workflow designed for speed, reliability, and work on the move — checklists, jobs, and sync that survive bad connectivity.
Knowledge Copilot
A grounded assistant that turns private knowledge into useful, cited answers — retrieval-backed responses with no hallucinated sources.
Workflow Agent
An intelligent automation layer for repetitive, high-context product workflows — steps a model can draft, a human can approve, and a system can audit.
Digital Asset Wallet
A self-custody experience that makes complex transactions feel understandable — clear signing, clear fees, and no surprises.
On-chain Analytics
A transparent data product for exploring contracts, activity, and asset movement — indexed, queryable, and fast enough to explore live.
What I do
One engineer.
The whole product.
I connect product thinking, interface craft, architecture, and delivery so good ideas don't get lost between disciplines.
Web Development
Scalable products, platforms, and APIs built end-to-end.
Mobile Apps
Native-feeling experiences for iOS and Android.
AI Development
Useful LLM products, retrieval systems, and agents.
Blockchain
Wallets, contracts, and dependable on-chain interfaces.
About Willy
Built on curiosity. Refined by experience.
Over 14 years, I've worked across the full software lifecycle—from early product strategy and interface design to backend systems, mobile delivery, and production operations. Recently, my focus has expanded into practical AI development: building tools that are trustworthy, measurable, and genuinely useful.
