Websites, apps and MVPs
A business website, a customer portal or a new online service. I'll help choose the features for the first release and build the interface, backend and admin tools it needs.
I'll build
the software
you need
I'm Sergei. I've been developing software since 2009. I build websites, bots, scrapers and tools that automate everyday work. Bring me an idea or a process that's taking too much time. I'll help work out the approach, build it and get it running.
I can help with the domain, hosting and launch too.

01 / HOW I CAN HELP
What would you like to get done?
These are some of the things I can help with. Have something else in mind? Tell me about it, and we'll work out how to build it and what it would cost.
Bots and scrapers
A Telegram bot for enquiries and notifications, a price tracker or a tool that collects website data into a spreadsheet. Tell me where the data comes from and what you want to do with it.
Automation and AI
I can connect your CRM, email, spreadsheets and other services to cut down on manual work. That could mean processing enquiries, generating reports or using AI to search your documents and draft responses.
Fixes and new features
I can work on an existing app, find the cause of a bug or sort out unreliable deployments. I'll read the relevant code and explain the changes I recommend before starting.
Domain, hosting and launch
I'll help you choose and register a domain, find hosting and set up the server, HTTPS and updates. The domain and accounts will belong to you; we'll discuss recurring costs before setting anything up.
02 / MY WORK
Some of my work
WEBSITE FOR A HIKING CLUB
Kojori Coin
A website where club members find hiking routes, share photos and plan outings.
I worked on the interface in Russian and English, the Go backend and deployment. Visitors can read route descriptions and download GPX tracks. Members have accounts and a club calendar, while organizers manage content and confirm participation.
- Frontend
- Go backend
- Deployment
For visitors
Routes in Russian and English, photos and GPX files to download.
For members
Accounts by invitation, planned outings and participation confirmed by organizers.
For organizers
Tools to edit drafts, publish routes and manage photos and club content.
Kojori Coins are points for taking part in club activities. The site doesn't handle cryptocurrency or payments.
WEBSITE FOR A ROPE ACCESS COMPANY
Promalp Georgia
A website for a company that handles installation, repairs and maintenance at height across Georgia.
I worked on the React and TypeScript site, its enquiry API and deployment. Visitors can read about the services, see examples of the company's work and send an enquiry. The site is available in English, Russian and Georgian.
- React interface
- Node.js API
- Deployment
Three languages
English, Russian and Georgian pages with a language switcher and localised search metadata.
Project enquiries
A contact form connected to a Node.js API that validates submissions and sends email notifications.
Launch and updates
Container deployment, automated release checks and health monitoring for the running service.
My other projects are covered by NDAs, so I can't share them here. I can talk about my role and general experience without disclosing client details.
03 / HOW I WORK
How we'll work together
You bring the idea and a budget. I handle the planning, development and launch. We'll agree on what you should get, the price and the timeline before I start.
- 01
Talk it through
Tell me what you want to achieve, how things work now and what budget you have in mind. I'll ask for the details I need and suggest an approach.
- 02
Agree on a plan
I'll set out the work, estimate it and suggest milestones. We'll write down what each stage includes and how you'll check it.
- 03
Build and review
I'll share working versions as I build. If something changes the estimate or needs your decision, I'll bring it up with you.
- 04
Launch and hand over
I'll test the agreed features and get the project running. If you need a domain or hosting, I can arrange that too. I'll hand over the code, access and setup instructions.

05 / PRICING
How we can start
QUESTIONS BEFORE WE START
Do I need a complete specification?
No. Tell me what you're trying to do or show me a process you want to improve. An example or a few sentences is enough to start; I'll help turn that into a plan.
Can you work with an existing application?
Yes. Show me what needs changing or explain the problem you're seeing. If I need to investigate the code before estimating a fix, we can agree on a paid review first.
What happens after delivery?
I'll hand over the source code, tests and setup instructions for the agreed work. If you need support or more features afterwards, we'll discuss the work and its cost separately.
Can you work on just one part of a project?
Yes. I can build the backend for an existing interface, connect an external service or help with deployment. Tell me what's already in place and where you need help.
Can I ask about something that isn't listed here?
Of course. Describe what you need, even if you're unsure what to call it. I'll look into the options, what is feasible and what it would take to build.
Can you help with the domain and hosting?
Yes. I'll help choose a domain and hosting, explain the ongoing costs and get the project online. We'll register the domain and accounts in your name so you have access to everything.
GET IN TOUCH
What do you have in mind?
A bot, a website, a task you want automated or an idea you haven't worked out yet — tell me about it. A few sentences are enough to start.
