Building SCRUM Teams from Scratch for Global Technology Companies

In one case, we helped build a greenfield team to develop a key application for the e-commerce industry; in another, we delivered specialists in record time who accelerated migration to an innovative Revenue Operations platform.

In both projects, j‑labs took responsibility for recruitment, technical verification, and competency matching, allowing clients to focus on their strategic goals. Our teams didn’t limit themselves to development – they actively proposed improvements, supported business processes, and seamlessly integrated with client organizations.

These experiences demonstrate that j‑labs can not only deliver people, but above all build autonomous, partnership-oriented teams that genuinely transform the pace and quality of projects.

Case Study No. 1

One of the global technology companies operating in the Revenue Operations area is creating an innovative platform that uses automation and artificial intelligence to support sales and operational processes in the B2B model. The solution enables comprehensive data analysis, performance forecasting, sales metrics tracking, and revenue optimization.

Business Challenge

The client approached j-labs with the need to urgently build a complete, highly specialized team of engineers to accelerate the development and improvements of two related tools supporting the customer migration process to the new platform:

1. Pre-Qualification Tool – used for data analysis and assessment of customer eligibility for migration.
2. Migration Tool – enabling migration execution by teams outside of engineering (e.g., technical support).

The client expected support both in developing these tools and active participation of the development team in the migration process itself.

Project Requirements

• Team: 5 people o 1x Tech Lead (Java – advanced, Python/JS – basic) o 4x Java Developers (in various seniority configurations – Senior, Mid)
• Team start: ASAP
• Tech Lead recruitment on the client side
• Remaining team members recruited and delivered by j-labs – exclusive project

Technologies and Tools

• Java 17 (Spring, Hibernate)
• Python 3 (simple analytical component, no frameworks)
• JavaScript (basic knowledge)
• Retool – low-code tool for interface creation
• Kubernetes (K8s) – deployment in AWS
• AWS – basic work with logs, databases (PostgreSQL via RDS), IAM, monitoring
• REST API, asynchronous queues
• Jira – task management
• Methodology: Agile (Scrum)

Implementation and Delivery

Recruitment and Onboarding Process

J-labs delivered a complete engineering team within several days according to the technological-competency profile and business requirements of the client. Tech Lead recruitment was conducted jointly with the client, remaining team members were delivered by j‑labs on a priority basis, in close cooperation with managers on the client side.

Team Work Scope

• Expansion of existing tools supporting the migration process
• Creation of new functionalities in Java and Python services
• Component integration using REST API
• Participation in migration work as operational support – data analysis, exception handling
• Proposing improvements resulting from migration experiences
• Maintenance and monitoring of components in production environment (AWS, K8s)

Results

• Rapid allocation of a competent team according to the project profile
• Support at a critical project moment – the j-labs team helped accelerate the migration pace
• The substantive contribution of the engineering team translated into concrete tool improvements
• Seamless integration with the client team and Agile processes

Summary

The cooperation is an example of an effective partnership model where j-labs not only provides specialists but also actively participates in the development of the client’s products and business processes. The project required flexibility, high technological competencies, and understanding of end-user needs. J-labs successfully met these requirements, delivering a team ready to operate ,,immediately” and matched both technologically and operationally.

Case Study No. 2

A global technology company operating in the field of recruitment and talent management needed support in quickly building a specialized development team. The project was implemented for one of its largest end clients from the e-commerce industry and involved creating a new application enabling unified management of drivers from various courier companies.

Business Challenge

The company approached j‑labs with the need to create an exclusive team composed of experienced backend and frontend engineers who would be able to independently lead the development of a new solution in a high-load environment.

The project was implemented in a greenfield environment, with a modern technology stack and under strict end-client requirements. It was expected to deliver a team ready to work ,,immediately”, capable of independent operation, testing, and working in a hybrid model.

Project Requirements

• Team: 5 people • 4x Java Developer (seniority: 2x Senior/Expert, 1x Senior, 1x Senior/Regular) • 1x Frontend Developer (Angular/TypeScript – Senior/Expert level)
• Project start: ASAP
• Duration: 6–12 months (first order)
• Work mode: Hybrid – number of office days arranged individually
• Cooperation model: Team built and delivered exclusively by j-labs, without recruitment process on the client side. After conducting technical tests, j-labs recommended candidates directly to the project.

Technologies and Tools

Backend:

• Java 21, Spring Boot, Hibernate
• RabbitMQ (asynchronous communication, exactly-once issues, transactionality)
• PostgreSQL, MongoDB, Redis (cache)
• Microservice architecture
• AWS
• Observability: Grafana, Kibana
• Automated tests: e2e

Frontend:

• Angular 18, TypeScript
• Node.js (Express.js) – welcome
• Monorepo (NX), design system, NPM
• Playwright, Jest (automated tests)
• Swagger (working with API documentation)
• Redux
• RWD/AWD, accessibility (a11y), web application optimization

Implementation and Delivery

Recruitment and Onboarding Process

J-labs conducted a full recruitment process, including technical tests, competency verification, and selection of candidates meeting the client’s high requirements. Thanks to understanding the project needs and close cooperation with the client, the team was assembled in a short time, maintaining the highest quality standards.

The j-labs team entered the project as a technology partner, ensuring not only development but also active participation in solution design, testing, and application optimization.

Team Work Scope

• Design and implementation of a new system in microservice architecture
• Handling asynchronous communication using RabbitMQ
• Creating high-performance backend and frontend services
• Ensuring consistency and transactionality in areas requiring event processing
• Cache implementation, data access optimization, system performance assurance
• Development of Angular web application, adapted to various devices and compliant with a11y requirements
• Creation and maintenance of automated tests
• Cooperation with DevOps teams and application monitoring in production environment

Results

• Rapid building of a complete team meeting high end-client requirements
• Full responsibility for technical candidate verification on j‑labs side
• Delivery of independent, experienced engineers capable of operating without the need for support from client’s internal teams
• Work commencement according to the required schedule
• High quality of code, tests, and team communication, which was positively evaluated by the client

Summary

The cooperation with a company providing a recruitment platform for global giants shows the flexibility and effectiveness of the partnership model implemented by j‑labs. Rapid delivery of high-class specialists, full responsibility for the recruitment process, and high substantive quality of the team translated into a smooth start of the key greenfield project.

J-labs once again confirmed the ability to quickly build teams matched technologically, operationally, and communicatively to the most demanding business environments.
