Seven-year cooperation with one of the top 15 banks in the world

Our client is one of the top 15 banks in the world by market capitalization. Our cooperation started in 2015, during this period we extended the development team exponentially from 1 to 31 engineer and delivered over 30 projects.

Value delivered 

Collaboration between Sombra and the client has been lasting 7 years already. During this time the client has received:

30+ projects in 7 years

During the cooperation, the client launched over 30 projects with our development resources. Currently, 5 projects are in the development stage, 5 in production, 10+ in the PoC phase, and 5 - on support. Long-term involvement helps the customer to reduce costs and get greater business and development integration.

Strong technical expertise in backend, frontend, QA, and DevOps

By now, the bank’s development team mostly consists of our developers (31 engineers - Sombra, 18 - Innovation unit). Over seven years the team has extended from 1 developer to 31 engineers.

Startup attitude

At the early stage of cooperation, the client needed full involvement, therefore our team worked 70–80 hours per week in peak season to deliver a result. At that time, we had to be flexible and quickly adjust to changing requirements.


Adjustment to changing requirements

The customer gets a development team that constantly adjust to changing requirements. Every quarter we conduct joint planning sessions with the client to set priorities and determine the motion vector for the next period. 

31 engineer team management 

Moreover, we organize annual onsite trips for engineers and bi-annual trips for managers to customer location to ensure deeper immersion in the client’s business.

Сontinuous development and technical support

The time difference between North America and Ukraine allows us and the internal team to deliver almost continuous development and technical support. Also, we are planning to organize one support team that will work in the hours when neither our nor onsite team are working.

On-demand UX/UI designer and DevOps engineer

If the client requires additional resources we provide specialists from our team to close the need. We often provide UX/UI designers, since we’ve learned quite a bit about the platform over the last years. Also, our DevOps work on bank’s projects, when there is a need.
