Software and Instrumental Solutions
SIS brings together highly qualified specialists, state of the art tools and modern project management to deliver top of the line products and services. One of the main problems with outsourcing, that we saw during the years, while working for other outsourcing providers, is that getting external help often caused a big overhead on the clients side. SIS offers clients flexible team management, architecture design and development operations, keeping client side architects, software operation teams and project managers as much as possible up to date and happy, while minimising the time they have to spend with SIS. Our working motto is to only do that what makes sense at this exact working moment.

Modernising Legacy System
Many years of experience with "classic" enterprise enterprise technologies. Multiple successful projects for pulling legacy "monolith" systems apart and safely moving them to modern platforms. Projects done as a slow evolution process, when the monolith is put apart piece by piece and as a big bang, when the core functionality gets fully reverse engineered + documented and a fully functional replacement is brought into operation.
