Product Engineering.

I take a brief and bring it to a launched product — design, architecture, code, deployment, and the operational stuff that ships next to it. Solo when the project rewards focus, embedded when scope expands.

// product shapes

The kinds of products I take to launch.

Different products, same engineering bar. Below is the four-shape menu and the default stack I reach for on day one.

Elderdoc · Handigwerk

Marketplaces

Two-sided products with vetting, escrow, and dispute flows. Stripe Connect end-to-end.

Flowys

AI-native products

Chat, agent, and copilot products with proper context budgets and observability.

Futura admin

Dashboards & admin

Internal surfaces for operations teams — fast, opinionated, and respect their workflow.

Futura · Kaugmaon

Editorial & marketing

Content-driven sites with a CMS the team actually uses. Performance baked in.

  • +Discovery, scope-shaping, and a one-page technical plan
  • +Information architecture, data model, and key flow design
  • +Full implementation in Next.js / TypeScript / Postgres
  • +Auth, payments (Stripe / Stripe Connect), file storage, and integrations

// outcomes

What you can expect.

  • ▶A production-ready product, not a demo
  • ▶Clean codebase another engineer can take over without a war-room
  • ▶Documented decisions you can defend to investors and auditors
  • ▶Lighthouse 95+ on the first ship — not a follow-up sprint
// process

How an engagement runs.

01
Diagnose

Three questions before code: who is this for, what does success look like in 90 days, and what is the worst case if it ships wrong.

02
Design

Information architecture, data model, and the two or three flows that carry the product. No Figma theater — only what we'll build.

03
Engineer

Boring tech by default. Production constraints baked in early — auth, payments, storage, and the deploy story on day one.

04
Refine

Performance, accessibility, copy, and the corners that decide whether the product feels respected or rushed.

// best fit

Best for.

  • ◇Founders shipping a v1 they need to defend
  • ◇Teams replacing a stalled vendor build
  • ◇Existing products that need a real engineer for a defined sprint
// pricing

Engagement & pricing.

Most engagements run 6–12 weeks. Fixed weekly rate or fixed-scope. I quote both ways.

Default stack
  • Next.js
  • TypeScript
  • PostgreSQL
  • Stripe / Stripe Connect
  • Vercel
