Custom web application development
I build web services, client portals, MVPs and SaaS on Django, FastAPI and Next.js, and run the project myself from spec to production. An MVP costs noticeably less than at an agency, and the code and access stay with you.
What do I build?
Client portals
A client or partner area with orders, documents, statuses and payments, on top of your site or as a separate service.
MVPs to test an idea
A first product version with one or two core scenarios that you can show to customers or investors.
Integrations and internal tools
ERP-to-site sync, scrapers, API bridges between systems, admin panels for your sales team.
SaaS platforms
Roles and permissions, subscriptions and billing, a public API, several companies in one system.
How much does a web application cost?
My estimates contain only development hours, with no manager or analyst time on top. Below are starting prices; I calculate the exact estimate after the brief.
Integration or internal tool
from $1,200
ERP sync, scraper, API bridge, simple admin panel.
2-3 weeks
Web service MVP
from $3,600
Auth, client area, one or two core scenarios, admin panel, deployment.
4-8 weeks
SaaS platform
from $7,200
Roles, subscriptions and billing, API, multi-tenancy.
from 2.5 months
Work on an existing Django, FastAPI, Next.js or Node.js project is billed hourly: $30 per hour within a support plan, $36 for one-off tasks.
I send a detailed estimate with stages and timeline within one business day.
How can you pay?
- Bank transfer on an invoice from my sole proprietorship, with closing documents for companies.
- Card or Russia's Faster Payments System (SBP) for individuals, with a receipt.
- In stages: an advance before work starts, the rest after each stage is delivered.
How does the work go?
Brief and scenarios
We describe who uses the service and what they do in it. That becomes the list of screens.
Estimate and architecture
I propose the stack and architecture and estimate hours per module. Then we sign a contract.
Development in sprints
Once a week I show a working version on a staging server. Priorities can change between sprints.
Launch and handover
I deploy the service to your server with backups and monitoring, then hand over the code, docs and access.
Why one developer instead of a team?
I design the architecture, write the backend and frontend and set up the server myself, so decisions don't get lost between people. That's how I built my own SaaS, PromptSpace: a marketplace with a catalog, payments and author payouts.

Web app development FAQ
How much does it cost to build a web application?
An integration or internal tool starts from $1,200, an MVP from $3,600, a SaaS platform from $7,200. The total depends on roles, screens and integrations; I send an estimate after the brief.
What stack do you use?
Python on the backend (Django, FastAPI), Next.js and React on the frontend, PostgreSQL for data. If you already have a project on another stack, I review the code first and tell you whether it's worth building on.
How long does an MVP take?
Usually 4-8 weeks. The fewer features in the first version, the sooner you get feedback from real users.
Who owns the code?
You do. The code lives in your repository from day one and the rights transfer under the contract, so you can hand the project to another team at any time.
What happens to the project if you can't continue?
The code, documentation and access are always with you, so the project doesn't stall. I write documentation and a README so another developer can pick it up.
