Experience with business-critical systems
Engineering for new systems, existing platforms and delivery teams that need additional capacity.
Software designed around the organisation, its processes and technical requirements.
Modern web applications, portals, self-service environments and internal systems.
Reliable backend services, APIs, business logic, distributed systems and integration layers.
REST/SOAP APIs, messaging, external services, legacy systems and cross-system data flows.
Connecting information systems to X-Road, including Estonia’s X-tee data exchange layer. The work covers producing and consuming services, security-server integration, and secure data exchange with surrounding systems.
Extending, refactoring and modernising existing systems while preserving business continuity.
Architecture, solution design, technology selection, feasibility and software engineering guidance.
Engineering expertise integrated into existing software delivery teams and contractor organisations.
Work
Software engineering for enterprise and public-sector systems. The references below describe iLab’s contribution, not sole ownership of the platforms.
01
Andmejälgija & Nõusolekukeskus
Full-stack software engineering for services within Estonia’s national e-government environment.
The work covers backend and frontend development as well as integrations with surrounding information systems and services.
02
E-Service
Full-stack development for the Estonian Transport Administration’s digital self-service environment.
The work includes backend services, frontend functionality and system integrations supporting digital transport-related services.
03
Invoicing
Software engineering for invoicing systems in a large telecommunications environment.
The work covered full-stack development, backend services, frontend functionality and integrations with surrounding systems.
Expertise
Our core expertise is Java-based software engineering, complemented by modern frontend technologies, databases, integration platforms including X-Road / X-tee, cloud infrastructure and engineering tooling.
We choose technology according to the system and its requirements — not the other way around.
Java, Spring, Spring Boot, Spring Security, Hibernate / JPA, TypeScript, JavaScript
React, Angular, Vue.js, HTML5, CSS / SCSS
PostgreSQL, Oracle, MySQL / MariaDB, MongoDB, Redis, Elasticsearch
REST, SOAP, OpenAPI, X-Road / X-tee, Apache Kafka, RabbitMQ, JSON, XML
Docker, Kubernetes, AWS, Microsoft Azure, Linux, Nginx
Git, GitLab CI/CD, GitHub Actions, Jenkins, Maven, Gradle, SonarQube
JUnit, Mockito, Testcontainers, Selenium, Playwright
Microservices, Event-driven Architecture, Domain-Driven Design, CI/CD, Secure Software Development
Some projects require a complete software solution. Others need experienced engineering capacity inside an existing delivery organisation.
We work with software houses, public-sector contractors and enterprise teams.
Selected work has been delivered through established contractor organisations, including:
Software should remain understandable and manageable over time.
Business-critical systems need predictable behaviour and careful engineering.
Modern systems rarely exist in isolation.
Technology decisions should solve real problems without unnecessary complexity.
