I build complex web platforms and apps

LMS, booking and payment systems, client portals and mobile apps — from architecture to release. I've worked on VK learning platforms, table payments for Coffeemania and the Skolkovo Technopark tour site.

Services

How I work

  • Understanding the task

    We discuss who will use the product and what they need to do with it. We agree on what to build first and what can wait.

    • Requirements for the first version
    • Technology choices
    • Timeline estimate by stage

  • Design

    I plan how to store the data, what the interface needs from the API and how to connect the product to other services.

    • Database schema
    • API and integration specifications
    • Prototypes of the main screens

  • Development

    I build the interface, write server logic and connect payment providers and other services. In a team, I also review other developers’ code.

    • Frontend and backend
    • Payments, notifications and integrations
    • Automated tests and code review

  • Release and support

    I prepare the release and check that the product works after launch. I investigate bugs and make changes based on how people use it.

    • Build and deployment
    • Checks of the main user flows
    • Bug fixes and new features
