What I build

One engineer, the whole stack.

From the first line of UI to the program running on-chain — built to a single, consistent standard.

Web Apps

Ship a fast, polished product your users actually enjoy.

Production React/Next.js apps with clean architecture, great UX, and performance that converts.

  • Next.js / React
  • Design systems
  • Edge & SSR
  • Core Web Vitals

Platforms & APIs

Scale from idea to a multi-tenant platform without rewrites.

Typed APIs, auth, billing, dashboards, and the boring-but-critical infra that keeps it running.

  • REST / tRPC
  • Postgres
  • Auth & billing
  • Background jobs

Windows Desktop

Native-feeling desktop tools your team installs and trusts.

Performant Windows applications — from internal tooling to distributable installers.

  • .NET / Tauri
  • Auto-update
  • Installers
  • System integration

Android Apps

Reach users on mobile with a smooth, store-ready app.

Android applications built for performance and a clean, modern feel — to Play Store and beyond.

  • Kotlin / RN
  • Offline-first
  • Push
  • Play Store

Solana / Web3

Launch on-chain features that are fast, cheap, and trustworthy.

Solana programs and dApps — wallet flows, on-chain reads/writes, and clean web integrations.

  • Anchor programs
  • Wallet UX
  • SPL tokens
  • RPC integration

How I work

A calm, senior process.

Solo means no handoffs, no telephone game — you talk to the person building it.

01

Scope in a call

We pin down the real goal, constraints, and what success looks like — before any code.

02

Ship in slices

Working software early and often, in small reviewable increments you can react to.

03

Measure & hand off

Performance, analytics, and docs so the result is fast, observable, and yours to own.
