HOW I WORK

A product career built around ownership.

I’ve moved between code, product decisions, operations, and the uncomfortable conversations that make a company better. The common thread is taking an unclear problem and carrying it all the way to something people can use.

WHAT YOU GET
  1. I talk to users before I prescribe a solution.
  2. I can move from product framing to Rails, Vue, APIs, and infrastructure.
  3. I care about the boring operational details that keep a product alive.
  4. I ship a useful version, measure what happened, and iterate without drama.

Stealth Startup

Building an early-stage consumer platform end to end — project management, development, design and branding — and owning everything that touches money.

  • Accounting and bookkeeping: specified and built the ledger, with linked registers, reversal rules, daily control totals and reconciliation.
  • Money in and out: card and crypto payment providers with signed webhooks and idempotent requests, digital-item payment and delivery rails, withdrawals with holds and staff review.
  • Affiliate commissions, promo codes, cashback and treasury exposure as versioned policies, plus a payment-provider simulator (hosted and transparent checkout, refunds, chargebacks, webhook replay) so every money path is tested before it is real.
  • Bun, Elysia, Drizzle, PostgreSQL and a transactional job outbox; React 19 on a token-based design system; Kubernetes with WAL-G backups.
  • Project management and brand: specs, backlog, decision register, PR reviews and engineering handoffs; the visual identity and design system.
