01 / Independent full-stack engineer

The site, the admin panel, the app — built to fit your business.

Some businesses need a clean site that sells their service well. Others need bookings, payments, a staff panel and a mobile app. Both are normal work here: a small project gets the same care as a platform.

What I can build

Start with the result, not the technology list.

A useful first version can be small. The same collaboration can grow into the system that runs the business.

A site that starts selling

For a beauty or nail studio, cafe menu, apartments, hotel, restaurant, personal brand or local service.

A tool that removes manual work

Bookings, schedules, payments, forms, staff workflows, reports and bots joined into one clear flow.

A platform built to scale

A customer product, custom admin, mobile apps, roles, data, integrations and automation — designed as one system.

Four real products. Open them and try the actual screens.

Working together

From a first call to a launched product.

Understand the work first

We start from how the business actually runs: who does what, where time is lost and what must never break.

Right-size the solution

You get the smallest version that solves the problem, and a clear picture of what it can grow into later.

Build and launch

Working software early, honest progress along the way, and a launch on real infrastructure — with tests wherever money or data is involved.

Stay close after launch

The products on this site run daily without a developer on call. Support, improvements or a clean handover — whatever fits.

About

I build the whole system, then stay close enough to see it run.

My work spans product, frontend, backend, data and operations. That range matters when a payment callback changes an admin screen, a report changes a campaign, or a staff habit should change the interface.

The projects here are live: a yoga studio platform, an online game’s live-ops stack, an indie publisher storefront and a cafe’s banquet builder.

I prefer few dependencies, explicit rules and software a non-technical team can run without a developer on call.
