Webko · Vilnius, Lithuania

Spring Boot Developer in Vilnius

Webko is a Vilnius-based web development company led by Andrii Kokov — a full-stack developer with 15+ years in web application development and 25+ years in IT. We design and build Java Spring Boot back-ends and APIs on PostgreSQL, and pair them with Angular front-ends when a project needs both ends — for startups, product teams and enterprise clients.

What a Spring Boot developer from Webko does

• REST APIs and back-end services — Java, Spring Boot, request validation, documented and versioned APIs for web and mobile clients.
• PostgreSQL and Redis — schema design, migrations, query tuning, caching and sessions.
• Authentication and integrations — session-based authentication, access levels and permissions, reCAPTCHA and third-party service integrations.
• Reports and background processing — report generation (JasperReports), scheduled tasks, data import and export.
• Migration and upgrades of legacy projects — including code review and refactoring of existing Java back-ends.
• Unit and integration tests, CI/CD deployment, architecture design and team leading.

Spring Boot with Angular and PostgreSQL

A back-end is only half of a product, so Webko builds the front-end too: Angular, TypeScript and Ionic for web and mobile. One team owns both ends of the contract between front-end and back-end, from the database schema to the user interface. We also add AI features to existing products — LLM integrations and MCP tooling.
