React Consulting Services for Product Teams

Senior React and Next.js help for teams that need architecture, not another pair of hands. I've shipped production React for fintech, web3, and developer-tools companies, and led the teams behind it.

When React projects need a consultant

React is easy to start and hard to scale. The patterns that worked for the first 20 components stop working at 200. The Provider tree turns into a rendering hazard. State management splinters. Type safety leaks at every API boundary. These are the moments a senior consultant pays for themselves in a quarter.

  • Architecture is drifting

    Multiple state-management libraries, inconsistent data-fetching patterns, no module boundaries. I run an architecture review and ship a written plan with the migration sequence.

  • Next.js performance is failing CWV

    LCP regressions, hydration costs, third-party scripts ballooning INP. I rebuild the critical render path and the metrics with it.

  • The design system isn't a system

    Components copied across apps, prop APIs diverging, tokens scattered. I implement a single packaged design system with versioned releases and codified primitives.

  • TypeScript is in name only

    any everywhere, // @ts-ignore in the hot path, no codegen at API boundaries. I tighten the types and the guardrails that keep them tight.

What I actually do

Architecture review

One to two weeks. Codebase walkthrough, team interviews, written report with prioritized action plan. The audit pays for itself in the decisions it prevents.

Build engagements

Embedded senior React/Next.js engineer for 8–16 weeks. Ship features, run code review, leave the codebase better than I found it. Weekly demos, written summaries.

Fractional frontend lead

1–3 days a week. Architecture decisions, hiring rubrics, design-system governance, mentoring. For teams that aren't ready for a full-time head of frontend.

Where I go deep

State & data

Zustand, Redux Toolkit, React Query, Apollo, urql. Context patterns and selector libraries. Server components and the React 19 model.

Performance

Core Web Vitals, LCP optimization, bundle splitting, Next.js edge/runtime tradeoffs, image strategy, font loading.

TypeScript

Discriminated unions, mapped types, conditional types, codegen from OpenAPI/GraphQL, strict mode rollouts in legacy codebases.

Design systems

Tokenized themes, headless component primitives, packaged distribution via private npm, Storybook governance.

Monorepo architecture

Nx and Turborepo, module boundaries, shared library design, build caching, CI strategy for many-package repos.

Headless CMS

Directus and similar headless-CMS stacks integrated with Next.js, type-safe GraphQL codegen, content modeling for non-engineers.

Selected React work

  • Kintsu. Liquid staking interface on a high-perf EVM chain. React, Next.js, viem/wagmi, design system from scratch.
  • Kedify. Kubernetes autoscaling dashboard. React, TypeScript, real-time data, complex form/state surfaces.
  • Reusable UI package. Internal design-system npm package consumed across multiple Next.js apps; reduced new-project setup by 40%.
  • Directus + Next.js. Type-safe CMS architecture with GraphQL codegen powering production marketing surfaces.

Frequently asked

What does a React consulting engagement look like?
Most engagements start with a one-week audit to understand the codebase, team, and the actual problem. From there we agree on scope (build work, advisory, or a fractional lead seat) and ship in two-week cycles with written reports.
Do you only work with React, or also Next.js?
Both. The majority of my recent work is Next.js (App Router and Pages), but I've shipped production React with Vite, Remix, and React Native. Astro for content-heavy and marketing surfaces.
Can you take over a struggling React project?
Yes. Brownfield rescues are a common engagement. I come in, audit what's there, stabilize the build and the team's confidence, then ship the next milestone. The first deliverable is always a written assessment so you know exactly what you're paying to fix.
How is this different from hiring a React agency?
Agencies sell teams. I sell a single senior engineer with team-lead experience. Better fit for companies that already have engineers and need senior judgment, not more hands. Worse fit if you need a full pod from scratch. In that case I'll refer you to one of the agencies I trust.
