I find where you are losing time, leads or money

And I build a system around it: a website, CRM, bot, Mini App or automation. I treat every project as my own.

Who I am

My name is David. I go through the task myself and do the development myself.

  • You talk to me directly – no account managers, no bots.
  • I take on no more than three projects at a time.
  • I reply within 40 minutes, from 8:00 to 22:00 (UTC+7).

Systems built around your work

We find where manual work eats the most of your time. Then I build a tool that fits it.

Talk through my task

Website or landing page

A website from scratch, no page builders. Always a custom design, with the request form already built in.

Website · landing page · request form

CRM system

Clients, statuses, requests and stats in one place. I set up the integrations you need and keep everything as simple as it can be.

Web CRM · built to fit · roles and access

Bots and Mini Apps

Booking, ordering or buying right inside Telegram. The client picks what they want, and you get a complete request.

Telegram bot · Mini App · payments

Automation

I connect your services to each other. Not sure what to automate – I will help you find it.

Reminders · reports · service integrations

These tools can work as one system: the website takes the request, the CRM saves the client, the bot sends the notification. See pricing

Flagship case

FlyGuru

Website and management system
for an efoil school

The public website collects requests – all of them land in the internal CRM. Clients, lessons, passes, stats, shifts and payroll – all in one place.

  • 140+clients
  • 170+lessons
  • 26days to
    launch
  • 8pages
    + CRM
Open the website

First real project

Store
inside Telegram

Menu, cart, payment and reordering – on the customer’s side. An admin panel with products, customers, statistics and broadcasts. All in one app.

  • 580+orders
  • 150+clients
  • 44%came back

90+ orders from the most active customer
4 orders a day on average
9 days from approval to the first order

Open @100lovaya_bot

The bot runs reliably, everything is thought through to the smallest detail, and the interface is clear and easy even for new users. I especially want to mention David’s responsibility, speed and involvement – he genuinely cares about the result and suggests good solutions instead of just “doing the task”.

What else I have built

Cover of the course “Перезавантаження настрою”
Online course

MoodBot – the course “Перезавантаження настрою”

Card payment inside the bot or on the landing page. Access opens automatically after payment – with no involvement from the author at all. The next lesson stays locked until the previous one is done. If someone drops off, the bot reminds them itself.

AGENTBOY – a DJ press kit

One page with everything that matters: announcements, releases, links to sets and streaming platforms. It is a portfolio, only for music. Handy for introducing yourself quickly or sending it to a potential partner.

  • GitHub Pages

He listened carefully to everything I wanted, understood the task quickly and built it exactly the way I had in mind. Every edit and extra request was taken on board without a problem.

I also want to mention that David even helped me buy the domain. In just two meetings we settled all the main questions and got an excellent result.

Process

How
I work

First we talk through the task and the features and agree on the price. Then I start building and send you beta versions along the way.

01

Discussing the task

We go through your question over chat or a call. We look at the task from different angles and pick the best solution together.

02

Plan and fixed price

We define the scope and how the features should work. We agree on the price and the timeline – and then I start.

03

Building

While I build, you get access to work-in-progress versions, so you can try everything yourself and tell me what to change.

04

Launch and support

After launch I keep a close eye on how it runs. I fix my own mistakes free of charge for a year.

FAQ

Common questions

How long will the development take?

Rough guide: a Telegram bot – about 7 days, a Mini App – about 14 days, a website with CRM – from 30 days.

Timelines depend on the scope of the task.

How does the work start?

We discuss your task over chat or a call. We look at it from different angles, and then I propose a solution and name the price and the timeline. I can also look at a product you already have: it may be enough to improve it.

How does payment work, and can the price go up?

I work with prepayment: 50% before the work starts and 50% after launch. For a large project we agree on the payment schedule separately. The agreed price does not change as long as the work stays within the agreed scope. New features and changes after the start are paid separately.

Who owns the code, the domain and the database?

You do. We open the accounts in your name from the start: the repository, hosting, domain and database stay under your control.

What happens after the product launches?

For the first week I watch closely how it runs. After that my code is under warranty for a year. If you want me to keep an eye on the product and keep developing it, there is monthly support.

What are your working hours?

I am available from 8:00 to 22:00 (UTC+7) and try to reply within 40 minutes.

Shall we talk about your project?

Tell me what eats the most of your time. I will go through the process, propose a solution and name the timeline and price before any work starts.
