From the database up to the user's screen

Custom software development

Desktop, server and service applications in C#, .NET and C/C++ — built for reliability, performance and long life.

System architecture

Client-server and distributed systems: multithreading, TCP/UDP listeners, custom protocols, message queues and load balancing.

Database design & administration

MS SQL Server schema design, T-SQL, performance tuning and day-to-day DBA — plus MySQL and ArangoDB.

Web & mobile applications

Web applications and services, JavaScript front-ends and cross-platform mobile apps with React Native.

Reporting & integration

Crystal Reports and web-based reporting, and integration between systems through web services and MSMQ.

Full-cycle project delivery

Requirements (SRS), top-level and detailed design, development, on-site installation, then ongoing support and monitoring.

Experience

Proven where downtime is not an option

For 14 years our founder led the teams behind automated fare-collection (AFC) systems used by public transport every single day.

  • Complete fare-collection systems for major Israeli bus operators — on-board devices, back-office, clearing and reporting.
  • Ticket vending machines, point-of-sale and card-loading applications for a metropolitan rapid-transit network, built together with a global IT corporation.
  • International transit projects in Nigeria, Kazakhstan and Cyprus.
  • Today: ongoing full-stack development for an Israeli technology company.

About

Dimitry Kalinichenko

Founder & CEO

Dimitry has been designing and building software for more than 25 years. Before founding D.K. Software Solutions in 2016, he spent 14 years leading software and database teams that delivered fare-collection systems to public transport operators in Israel and abroad.

He works across the whole stack — from the data layer and business logic to the user interface — and runs every project end to end: requirements, design, development, installation on site, and support afterwards.
