We build the hard parts and ship the whole thing.

Senior engineering for startups and teams: product web apps, 3D in the browser, AI that holds up in production, and the cloud it runs on.

engagement

Ways to work together.

Fixed-scope project

A defined product or feature, a fixed quote, weekly releases you can click through.

Monthly retainer

A senior engineer on your product every month: roadmap, builds, reviews, upkeep.

Technical audit

A fixed-price review of an existing app: cost, security, reliability. Report in 5 business days.

process

How a project runs.

    Discovery call

    30 minutes, free. What you are building, for whom, and what done looks like.

  2. 02

    Scope & quote

    A written plan: features, architecture, timeline and a fixed price or monthly rate.

  3. 03

    Build in the open

    Weekly releases to a staging link. You see progress, not status reports.

  4. 04

    Launch & hand over

    Production deploy, docs, and the code in your repository. Support if you want it.

faq

Questions, answered.

Anything else? Ask directly.

Do you work with early-stage startups?

Yes. A lot of the work is taking a product from idea or rough prototype to something customers pay for. We will tell you what to cut to launch sooner.

Who owns the code?

You do. Everything lives in your repository and accounts from day one.

How do you price?

Fixed quotes for defined projects, a monthly rate for retainers, and a fixed price for audits. You get the number in writing before any work starts.

Where are you based?

India, working with teams anywhere. Calls overlap with European and US mornings.
