React & Next.js web apps and dashboards

I build custom web applications, internal dashboards and Next.js migrations with React, Next.js and TypeScript, on a proper CI/CD and testing setup. You get an Engineering Manager with 15+ years of experience who still writes the code, so architecture, performance and accessibility are built in from day one.

Best for
Teams that need a new web app or dashboard, or a move off a legacy frontend.
Stack
React, Next.js, TypeScript, Node.js, headless CMS such as Strapi
Includes
CI/CD, automated tests, documentation and a handover

What I build

  • Customer-facing products

    Booking flows, calculators, locators and multi-step forms that stay fast on mobile.

  • Data-heavy dashboards

    Dashboards that stay responsive with large data sets and complex filters.

  • Internal tools & admin panels

    Tools your team can use without a developer, like the CMS behind this site.

  • Migrations to React & Next.js

    Incremental moves off legacy frontends, without freezing feature work.

Details

End-to-end web app development — data-heavy dashboards, internal tools, customer-facing products — built with React, Next.js, TypeScript and a proper CI/CD and testing setup.

Proof from real projects

Experiments

What you can expect

  • Architecture first

    A structure your team can extend, not a one-off build.

  • CI/CD and tests from day one

    Every change is checked and built automatically before it ships.

  • Performance, SEO and accessibility

    Server rendering, semantic HTML, metadata and Core Web Vitals are built in.

  • AI-assisted, human-reviewed

    Coding agents for speed, with guardrails on the parts users actually feel.

In short — Aman Kumar Sinha's recommendation

An exceptional leader who bridges high-level strategy with deep technical execution: quick to find the root cause of complex architecture problems, and able to align cross-functional teams and keep delivery on track without sacrificing quality.

Frequently asked questions

Can you migrate our existing app to Next.js?

Yes. I've led the modernization of two legacy applications onto React and Next.js, which cut build time by 30%. Migrations usually go route by route so the product keeps shipping.

Do you build the backend too?

I build the Next.js route handlers and Node.js APIs the frontend needs, and integrate with your existing APIs or CMS. For larger backend systems I work alongside your backend team.

Will it be SEO-friendly?

Yes. Server rendering, semantic HTML, page metadata, structured data, sitemaps and Core Web Vitals are part of the build rather than an afterthought.

What happens after launch?

You get documentation and a handover walkthrough. If you want ongoing help, that's covered by Team mentoring & technical advisory.
