CRM, integrations
and applied AI.

I set up CRMs and connect services through APIs. I build n8n automations, AI agents and RAG systems.

PROJECT 01 / CLIENT PROJECT

Construction company CRM

Built the website, the estimate calculator and the CRM. Building parameters, the estimate, the deal and the commercial proposal are linked in one system. After launch I kept shipping changes based on the client's feedback.

PROJECT 02 / CLIENT PROJECT

Content platform

Reworked the content preparation stages, the approval interface, integrations and media processing in the Telegram bot and Mini App. Wrote the handover documentation.

PROJECT 03 / CLIENT PROJECT

Purchase tracking

Built a spreadsheet for product items, tasks and deadline control. Set up autofill, highlighting of problem items and an archive. Reworked the structure after the client's feedback.

HOW IT WORKS / PICK A NODE

Add an item

An employee enters the product and working data. Empty service fields fill in automatically.

Diagram of the implemented process. Live connections and data are not shown.

PROJECT 04 / INTEGRATION DEMO PROJECT

RetailCRM + API

Built order sync from RetailCRM to Supabase, a web dashboard and a Telegram bot. Records are updated by the CRM order ID. Alerts can be acknowledged in the bot.

HOW IT WORKS / PICK A NODE

RetailCRM API

Orders, statuses, items, totals and custom fields.

Diagram of the implemented process. Live connections and data are not shown.

PROJECT 05 / OWN ENGINEERING SYSTEM

AI agents

One Telegram bot backed by several agents: it finds and scores job openings every night, drafts applications, sorts the knowledge base, hands coding tasks to Codex and creates Telegram bots. Anything that leaves the system goes out only after I confirm it.

HOW IT WORKS / PICK A NODE

Telegram + Hermes

One entry point, schedules, skills and tools connected through MCP.

Diagram of the implemented process. Live connections and data are not shown.

PROJECT 06 / OWN ENGINEERING SYSTEM

n8n + AI monitoring

Built collection of financial data from APIs, processing in n8n and storage in Supabase. A Telegram Mini App is used for viewing; AI workflows analyze events.

02 / SERVICES

What we can
build together.

Come with a single integration, a CRM change, or a problem where the solution still needs to be chosen.

01CRM setup and customization

I set up records, pipelines, user permissions and deal actions. I add pricing, documents and deadline tracking. If the task needs its own tracking system, I build one.

For a construction company I built a CRM with cost estimates and proposal generation. For a purchasing team I set up item, deadline and problem tracking in Google Sheets.

02CRM and API integrations

I connect your CRM to your website, database, spreadsheets and bots. I define which fields move and how records are updated. I test the sync against retries, incomplete data and outages of the other service.

In a RetailCRM demo project, orders sync to Supabase, show up in a dashboard and trigger Telegram alerts.

03n8n automation

I build workflows that run on an event or a schedule: they fetch data, validate it, update records and send notifications. Errors go to a log with retries. When a ready-made integration is not enough, I write custom nodes in TypeScript.

I run n8n on a VPS and have built community nodes for Telegram MTProto and workflows with LLMs and Telegram.

Example: data, n8n and AI monitoring ↗︎Discuss an automation ↗︎
04AI agents and RAG

I give agents tools and API access, set up how they process information and hand results to a person for review. I build RAG systems where the model answers from your own knowledge base, including the retrieval part that finds the right context.

To discuss this, it helps to have sample documents and the questions the system should answer.

05Web apps and bots

I build websites with lead forms and calculators, internal dashboards, Telegram bots and Mini Apps, and connect them to your CRM and database. Stack: Next.js, React and TypeScript.

03 / PROCESS

Work with me
directly.

You discuss the task with me. I design the system, write the code and hand over the result.

Start with a call ↗︎
Where to start

The first call is free. Show me a sample order, document or manual step and tell me what you want to change.

Price and timeline

The price is fixed per stage with a clear deliverable. If I first need to look into your code or API, we agree on a paid review; its cost is credited toward the build.

What you get

Before development we agree on what must work and how we will test it. After acceptance you get the source code of my work, documentation and access to your environment.

Running costs and support

Subscriptions, infrastructure, paid APIs and support are priced separately. How fixes and support work is agreed before we start.

Discuss a review of your current system ↗︎

04 / GET IN TOUCH

you have in mind

Describe the task and the systems you already use. A sample quote, document or manual step makes it easier to talk it through.
