vance

designer clothing brand — co-owner & sole developer

AD VANCE designer clothing brand · co-owner & sole developer · 2021 — present Built and own the full-stack e-commerce platform behind the brand. React and Next.js on Vercel, with a custom Stripe preorder checkout — payment holds, order queuing and fulfillment tracking — plus a PostgreSQL admin dashboard and CI/CD. Adborne is the same operation under a new identity: a themed drop site built on top of the platform, with a retro-arcade interface — press start, character select, HUD — wrapped around a real storefront. Two sites, one commerce backend.

lore

worldbuilding-driven clothing brand

LORE clothing brand · new york city A label that builds worlds first and clothes second. Each collection is a place with its own story — FW25 The Silver Plains, SS26 The Red Desert — with a Metallurgy line running through them. The storefront is built around that: collections read as chapters rather than product categories, so the narrative survives the transition from lookbook to checkout.

DREAMHOUSE creative design studio · new york city Site for a NYC design studio — portfolio presentation for a team whose work is the selling point, so the interface stays out of the way of it.

    surveyai

      Experience

      Engineer — SDKs, CLI & Platform — Fern

      Jun 2026 to Present

      • Built Fern Agent Automations, giving 100+ enterprise customers automated analysis and maintenance of their docs — one prompt plus a cron expression schedules recurring agent runs, and a one-time OAuth consent means every edit and PR carries the user's own permissions, not a bot's.
      • Ran automation doc edits as durable background jobs that wake the agent when they land, so it reports the resulting PR and notifies the user over email or Slack.
      • Ship features across Fern's SDK generators for nine languages — auto-generated idempotency keys, user-agent headers, webhook signature verification — raising the security and reliability baseline of every generated SDK.
      • Extended the Fern CLI with dual authorization and package identity customization, giving customers control over registry credentials and published package naming.
      • Shipped org-scoped data retention in the dashboard — deletion policies and on-demand purging for search queries, Ask AI conversations, preview sites and MCP data previously kept indefinitely — unblocking enterprise compliance.
      • Led enterprise migrations onto Fern — Sigma's 1,500-page move off ReadMe, and Mailchimp's full docs, SDK and CLI migration across nine languages.
      • Own bug triage across the SDK generators, CLI and dashboard — reproducing customer-reported issues, identifying root cause, and shipping fixes into the affected language generators.
