Frontend systems
React and Next.js interfaces with TypeScript and Tailwind — responsive, fast, and designed like the product is the brand.

I don't ship pages.
I ship systems.
Interfaces that feel inevitable.
APIs that stay quiet under load.
Stores that convert.
Markets that trade.
AI that actually makes it to production.

Work that shipped.
Ten live products. Commerce, ops, education, and on-chain — scroll sideways through the cut.

One engineer.
The whole machine.
Frontend is the opening title. Backend is the cut. I stay through the credits — models, CMS, wallets, and the deploy that has to work on Monday.

Hired for range.
Kept for taste.
02
Full-stack products
End-to-end applications: auth, APIs, data models, and deploys that hold together after launch day.
03
AI in production
OpenAI, Replicate, LangChain, Hugging Face — features that do something useful, not a chatbot bolted on for the deck.
04
Commerce & CMS
Shopify, Sanity, and WordPress systems editors can run without paging an engineer for every headline.
05
Web3 surfaces
Wallet-aware UIs, Cardano and Solana DEX floors, and RWA onboarding — speculative tech treated like real product.
06
Ship & operate
Vercel, Netlify, Heroku, GitHub Pages — deployment that is boring, which is the highest compliment.

Open for full-time and select contracts
I design and ship full-stack products — the interface, the API, the data, the deploy — for teams that need something real in the world, not another prototype.
The work spans print-shop operations, scholarship platforms, Shopify storefronts, Cardano markets, and tokenized real-world assets. Same standard every time: clean systems, sharp UI, and code a team can live with.
Stack of record: TypeScript, React, Next.js, Node, and whatever the product actually needs — Sanity, Shopify, Mongo, Rails, OpenAI, on-chain rails.
