Technologies and capabilities

Technologies supported by practical applications

I work across the full stack: Kotlin backend systems, native Android apps, web applications and websites. Database and infrastructure skills help me connect these layers into complete solutions that can be deployed and maintained.

Kotlin and backend development

Kotlin is my primary language. I use it to build backend services, APIs, authorization, business logic and integrations with databases and external platforms.

Kotlin, Spring Boot and APIs

I build backend services, APIs and integrations with clear responsibilities, understandable data models and testable business logic.

Technologies

Kotlin
Go
Spring Boot
Spring Security
Spring Data JPA
Hibernate
Ktor
REST API
OpenAPI
PostgreSQL
Redis
Docker

Applications

authorization and roles
business logic
integration testing
external integrations
webhooks
scheduled tasks

Android and mobile applications

I build native Android applications with Kotlin and Jetpack Compose, combining the interface, application state, data and backend communication into one architecture.

Mobile applications with Jetpack Compose

I design platform-aware screens and flows with clear application state, data, navigation and room for continued development.

Technologies

Jetpack Compose
Material 3
Coroutines
Kotlin Flow
Room
Dagger Hilt
biometrics
REST API
testing

Applications

application architecture
navigation
UI state
data handling
API integration
secure access
testing critical flows

Web applications and websites

I build backend-connected interfaces and content-focused websites with attention to responsiveness, accessibility, performance and technical SEO.

Web systems and dashboards

I build forms, dashboards and data views that reflect user roles and the actual processes supported by the system.

Technologies

React
Next.js
Astro
Tailwind CSS

Applications

forms and validation
state management
roles and permissions
API integration
testing

Next.js
CMS
WordPress
Tailwind CSS
HTML and CSS

Applications

SSG and SSR
i18n
schema.org
performance and SEO
content management
integrations

Data, deployment and maintenance

I work with databases and the environments required to run applications. I prepare projects so they can be reproduced, tested and developed after deployment.

Databases and modeling

I design schemas and migrations around actual application operations, focusing on consistency, indexes and model clarity.

Technologies

PostgreSQL
MySQL
Redis
SQL

Applications

data modeling
migrations
indexes
data integrity

Deployment and environments

I prepare repeatable environments and basic automation so applications can be launched safely and handed over without hidden setup steps.

Technologies

Docker
Docker Compose
Linux
GitHub Actions

Applications

CI/CD
environment configuration
logging
project handoff

Additional technologies and automation

I use smaller tools when they simplify a specific process: data import, scheduled work, an integration or a command-line utility.

Go and CLI tools

I use Go as a supporting technology for small services, command-line tools and tasks where straightforward deployment matters.

Technologies

Go
net/http
goroutines
context
SQL

Applications

lightweight services
CLI tools
concurrent processing
automation

Python and API integrations

I create scripts supporting data exchange, content publishing and repeatable tasks across external services.

Technologies

Python
HTTP API
web scraping
cron

Applications

data import and export
scheduled tasks
content publishing
service integration

Need technical support for a project?

I can build a product from scratch, take responsibility for a focused module or improve part of an existing application.
