Frequently asked questions
Short answers on scope, timelines and how we work
How much does a website or web application cost?
It depends on scope, integrations and timelines. After a short brief I send an itemised estimate broken down by stage — no hidden work.
How long does development take?
An MVP or landing page takes a few weeks; a full platform with backend and admin panel takes a few months. I work in iterations with interim demos.
Do you build both frontend and backend?
Yes, end-to-end: UI on Next.js and React, APIs and services on Node.js/NestJS and Python, PostgreSQL/MySQL/Redis databases and Docker infrastructure.
How is the work and payment structured?
Under contract, in stages: brief and estimate, sprint development, launch, support. Payment is per stage or hourly, as agreed.
What do you need to start?
Describe the task and constraints via the form or Telegram. Within one business day I reply with an estimate, a plan and implementation options.
Do you support the project after launch?
Yes: deployment, monitoring, backups, updates and further development — I offer ongoing support.
