Custom web app and SaaS development
I take on the whole product: I work out the problem, design the data and APIs, build the interface and backend, connect payments and external services, deploy and support it after launch. My portfolio includes VK learning platforms, table payments for Coffeemania, a media archive for broadcasters and a tournament system.
Why clients come
- You have an idea or a process that needs to become a working product
- You need one person responsible for both frontend and backend
- Your current system has hit the limits of a site builder or CMS
- The product has to grow: new roles, integrations, load
What I build
Architecture and data
Database schema, APIs and module boundaries — before development starts, so the product can grow.
Interface
React and Next.js, responsive layouts, server rendering where speed and SEO matter.
Backend
Node.js and NestJS or Python and Django, background jobs, queues, files in S3.
Authentication and roles
Email, VK ID or OAuth sign-in, permissions for different user types.
Payments and integrations
Acquiring, instant bank payments, CRM, POS, messengers and external APIs.
Launch and support
CI/CD, stage and production, error monitoring, post-release fixes.

What drives the cost
I send a stage-by-stage estimate after a call and a review of requirements.
- Number of roles and flows
- Integrations with external systems
- Load and reliability requirements
- Whether design starts from scratch or mockups exist
FAQ
Do I need a finished specification?
No. Describe the problem and the users — we'll write the first-version requirements together and move in stages.
Can the project be handed to another team later?
Yes. I write code another developer can understand and document the architecture and deployment.
Do you work alone or with a team?
I own the architecture, frontend and backend myself. If the project needs a designer, QA or DevOps, we agree on the team at the start.
What do you need to estimate a project?
Tell me what problem the product solves, who will use it and which systems it connects to. If there are no requirements yet, we'll work them out on a call, then I'll send a stage-by-stage estimate.
Why is the price shown as “from”?
It's the lower bound of the budget. The final figure depends on roles, integrations and load requirements — I give an estimate after reviewing the task.
