Project Description
I build Telegram bots that are connected to language models (OpenAI, Claude) and to the company's own knowledge base, so the bot answers using real prices, terms and FAQ instead of generic phrases.
Bots can show a catalog, accept payments, book time slots, transcribe voice messages and send every new lead with a short AI summary to the manager chat or CRM. An admin panel shows dialogs and statistics.
Examples: a dental clinic bot that books patients 24/7 straight into the doctors' schedule, a sneaker store assistant that picks models and takes payment in the chat, and a food delivery bot that accepts orders by voice message and sends a ticket to the kitchen.
Technologies Used:
- Node.js / Python bot logic, Telegram Bot API and webhooks.
- LLM API (OpenAI / Claude) natural answers, classification and summaries.
- RAG knowledge base answers based on the company's own data.
- CRM & payments leads, orders and online payments right from the chat.
OUR APPROACH:
Start with the most frequent client questions, connect the knowledge base and test the bot on real dialogs. The bot never pretends to know what it doesn't: uncertain cases go to a human with the full conversation history.
CRM & CMS
Implementation of CRM and CMS systems: all clients and deals in one pipeline, and website content that the team edits on its own, without a developer.

Oleksandr Kolesnyk
Project Description
I set up and integrate CRM systems so that every lead from the website, Telegram or email lands in the sales pipeline with its source, and the team sees deals, tasks and invoices in one place.
On the content side I connect websites to a CMS (Payload, Strapi, WordPress): pages are built from blocks, products and blog posts are edited in a convenient admin panel, with translations and SEO fields.
Examples: a CRM for a real estate agency with objects, viewings and AI matching of clients, a CMS for an online school where the team edits courses without a developer, and a beauty salon CRM with the masters' calendar, client history and bonuses.
Technologies Used:
- CRM (HubSpot, KeyCRM, Pipedrive) sales pipeline, contacts, tasks and invoices.
- Headless CMS (Payload, Strapi) content model, blocks, collections and media.
- WordPress familiar admin panel when the team needs it.
- API integrations website forms, Telegram and email connected to CRM.
OUR APPROACH:
First we describe how the team actually works with clients and content, then configure the CRM pipeline and CMS model around it, migrate existing data and train the team.
Automation
Automation of routine tasks with AI: incoming requests, documents, reports and notifications are processed automatically, and people only check the result.

Project Description
I build workflows that take data from email, website forms, Telegram or spreadsheets, process it with AI (classify, extract fields, summarize, draft a reply) and send the result where the team works: CRM, Google Sheets or Telegram.
Typical tasks: sorting incoming requests, filling reports, reminders and follow-ups, processing documents and weekly summaries.
Examples: invoices from the accounting inbox are read by AI and entered into the payments table, a coffee shop chain gets a content plan that is written and published automatically after approval, and an HR team gets hundreds of CVs ranked against the vacancy.
Technologies Used:
- n8n / Make visual workflows and scheduled jobs.
- Node.js custom integrations and scripts.
- LLM API classification, data extraction and reply drafts.
- Google Sheets, CRM, Telegram where results are delivered.
OUR APPROACH:
Automate one process first, measure how much manual work it removes, then move on. AI prepares, a person decides: important actions always stay under human control.

Project Description
I create 3D models and photorealistic renders of products and objects, set up materials and lighting, and prepare animations for landing pages, presentations and social media.
For websites I export models to web formats and build interactive scenes with Three.js: a product can be rotated, explored on scroll or used as an animated hero block.
Examples: a perfume bottle model for a cosmetics brand, an interior visualization with furniture color variants for a design studio, and an animated camera tour around a cottage for a real estate developer.
Technologies Used:
- Blender modeling, materials, lighting and rendering.
- Three.js interactive 3D scenes in the browser.
- GLTF optimized models for the web.
- GSAP scroll and UI animations around 3D scenes.
OUR APPROACH:
We agree on the style and references, make a draft model, then refine details, materials and light. For the web the models are optimized so that pages stay fast.
