Blockchain-focused engineer — smart contracts, dApp UI, and pragmatic delivery.
I'm a full-stack developer. I take a website or an app from the first screen through the API, database, and launch, and I keep the code maintainable after it ships.
That includes marketing sites, web applications, mobile apps, and the systems behind them: authentication, payments, admin tools, and deployment.
I also build the blockchain side: smart contracts, dApp interfaces, and the integration between a wallet and the rest of the product.
Share the product you want. I'll scope the work, build it, and hand over something your team can run.
A short list of what you can expect when we collaborate.
I like to nail milestones, acceptance criteria, and tradeoffs early so delivery stays predictable.
Threat modeling, tests on critical paths, and review checkpoints - not a last-minute checkbox.
Written progress notes, demo links, and honest blockers so you always know where things stand.
Env setup, error surfaces, and handoff docs included so launches are not a scramble.
The tools I use to ship websites, apps, and blockchain products: the interface, the API, the database, and the contracts.

}Answers to the questions I hear most often.
Yes. I can help shape scope, milestones, and technical tradeoffs before you lock requirements.
