Farlayer · Dmitrii Evseev, independent developer
From a business need to working software
I build websites that make your offer clear, connect your systems and automate routine work. I handle design, development and launch. You work directly with the developer, agree on scope and price upfront, and keep the code and access.
What does your business need?
These are starting prices. We agree on the exact price and scope before work begins. One round of revisions is included. Domain, hosting and paid APIs are billed separately to your accounts.
Websites for small businesses
Visitors understand your offer and can easily get in touch. I build and launch your site, then hand over the code and access.
- A clear offer and a direct path to enquiry
- Easy to use on phones and computers
- You control the code, domain and hosting
from $449

Over six years of commercial development, from integrations to systems with billions of records. Pick a problem like yours to see my approach, diagrams and the scale of real projects.
A system you can develop piece by piece
I help connect products, data and teams through a clear system design. I define service responsibilities, shared data and access rights so new features fit the existing architecture. In a geo-analytics project, this approach brought three separate products into one platform in four months, with shared data and sign-in and separate services for each area.
Data collection without the daily manual work
I automate collection from websites, catalogs and APIs so your team can work with the results. Scheduling, retries and progress tracking are part of the process. One platform I worked on supports over 50 background job types and more than 10 external sources, with jobs launched, cancelled and tracked in one place.
Analytics ready for growing data volumes
I help organise storage and processing when spreadsheets and manual exports are no longer enough. Ingestion, queries and reports are designed together. I have worked with stores holding billions of rows and over 500 GB of data, with batch and streaming ingestion while analytics remains available.
Keeping services available when a site fails
When downtime disrupts customers and your team, resilience belongs in the design. I plan service placement, data replication and routing to available sites. My distributed systems work has covered cluster and whole data-centre failures, with another site handling requests using replicated data.
Relationships that a spreadsheet can hide
I turn long lists of transactions into visual maps so researchers can find groups and test hypotheses. In a TON project, the data covers token holders and transfers between wallets: the system collects it, identifies connected groups and displays a graph. Caching and request controls help stay within external API limits.
Your tools, right in your AI chat
I connect your business systems to ChatGPT, Claude and other AI assistants. MCP gives the assistant access to the data and actions it needs: finding information, putting together a summary, creating a task or adding a meeting starts with a plain-language request in chat. Your team spends less time searching, switching between apps and copying data by hand. You choose which systems to connect and what to allow: reading only, or creating and updating records too.
Get work done in the messenger you already use
I make reports and notifications reach your team automatically, with work actions available from chat. I connect internal systems to Telegram, Mattermost and email to collect data, deliver results and process commands. I use this approach for reporting, message search and failure alerts.
By the numbers

From first message to launch
How I verify and hand over the work →Your task
What you want to launch, improve or stop doing by hand. A couple of sentences is enough.
The approach
I clarify the details and suggest a solution. We can discuss it in writing or on a call if you prefer.
The agreement
We define the result, scope, timeline and price before development starts.
Development
You see progress, try the work and discuss revisions along the way.
Launch and handover
We check that it works. You receive the code, access and instructions to keep using it.
What would you like to launch or improve?
Tell me what is getting in the way and what you want to achieve. You do not need a technical brief — I will help clarify the task and propose a scope.
