What you can hire me for

Senior product engineering, from architecture through shipped code.

Useful when a team needs staff-level React and Next.js help and does not want to open a full-time search.

Senior product engineering

Hands-on React, Next.js, TypeScript, Node.js, and GraphQL work, with senior ownership of the frontend without a full-time hire.

Frontend architecture and fractional lead

Shape the frontend system, or step in as fractional frontend lead when the team needs senior judgment and someone who still writes code.

Real-time systems

WebSockets, server-sent events, WebRTC, and Mapbox for products where latency, live updates, and failure modes matter.

Supabase apps

Auth, database, and storage for product work that should ship without standing up a large custom platform first.

Custom content and admin tools

Internal tools and content workflows on Next.js and Supabase, in place of an off-the-shelf CMS.

Why teams trust the work

Senior enough to shape the system, hands-on enough to ship it.

Consulting since 2005

A long consulting practice across startups, agencies, and product teams, with staff-level frontend and product engineering.

Staff-level React and Next.js

TypeScript, Node.js, GraphQL, design systems, performance, accessibility, and developer experience.

Fractional frontend leadership

Comfortable with founders, product managers, designers, and engineers when a team needs senior ownership without a full-time hire.

Hands-on delivery

Planning, implementation, testing, code review, release support, and practical communication.

When to bring me in

When the product needs senior frontend judgment, not just more tickets closed.

I work with founders, portfolio companies, and agencies that need someone who can make progress inside real product, design, and engineering constraints.

  • You need senior React, Next.js, or TypeScript help without adding full-time headcount.
  • A portfolio company needs a fractional frontend lead who can also ship.
  • An agency needs a senior frontend partner for a client engagement.
  • You are building real-time features, WebRTC, or Mapbox maps and need that experience in the room.
  • You want a custom content or admin tool on Next.js and Supabase instead of an off-the-shelf CMS.

How engagements work

Retainers, projects, or a fractional frontend lead.

Retainers start around 10 hours a week. A focused project or a fractional frontend lead role is a fit when the work has a clearer edge. The first conversation sorts out which one matches the problem.

Book a call
  1. 1. Project read. Sort out the goal, audience, constraints, risks, codebase reality, and what success should look like.
  2. 2. Practical plan. A clear technical path, scope, tradeoffs, and a recommendation for the smallest durable next move.
  3. 3. Build and improve. Hands-on work with your team or independently to ship, modernize, stabilize, and document the work.

Agencies and investors

Refer a founder or portfolio company.

If you place senior frontend help with startups, send an introduction. Include who you are, who needs the help, and whether it looks like a retainer, a project, or a fractional frontend lead role.

What a first conversation covers

A quick read on the work, then a concrete path to progress.

You do not need a perfect brief. A useful first conversation can sort out the problem, the constraints, the likely risks, and whether I am the right fit.

A clearer plan for scope, architecture, and delivery.

Production code in React, Next.js, and TypeScript.

Frontend architecture the team can keep changing.

Direct communication with the person doing the technical work.

Have a product that needs senior React and Next.js help?

Bring the product, the codebase, or the half-formed plan. I will turn it into a clear next step and start shipping.
