Hi, I'm Max.
Fullstack developer

I build sites and web apps, Telegram bots, integrations and AI features. Mostly TypeScript, with Python where it fits.

build --site --web-app

Landing pages, dashboards, shops, MVPs. Next.js, React, Astro, Node, Postgres.

build --telegram-bot

Orders, bookings, payments, admin panel, AI answers from your own content.

from $30

automate --scrape --report

Public data into Excel, Google Sheets or a database. Scheduled runs, alerts, reports.

connect --payments --crm

Webhooks with signature checks, retries and logs, so nothing gets lost.

add --ai

Assistants that answer from your own docs, text generation, agents that do the boring part.

fix --whatever-broke

Bugs, failed deploys, someone else's code — including apps built in Lovable, Bolt or Cursor.

1

You describe the task

In plain words. A link, a screenshot or an error text helps.

2

I scope it

Price and timing before I start. If it's a bad idea, I say so.

3

I build and test it

You get it working, plus a short note on how it's put together.

4

You pay

USDT or USDC. Small tasks after they work, longer projects in parts.
