Software Expertise                 

  • Ruby and JVM stacks
  • Algorithms, Big Data, machine learning (PhD level)
  • OOP, clean code, safe refactoring
  • leading and coaching software teams

Business Domain Specialties                            

  • FinTech (FIX, order routing, simulation software / backtesting)
  • EdTech (business process automation & data processing)
  • Telco (network service implementation, JAIN SLEE)
  • Travel Industry (GDS, search & booking systems)
  • E-commerce (Hybris, APIs integration)

Algorithms                            

Beside typical 3-tier programming on JVM and Rails stack we implemented:

  • genetic algorithms to narrow the space of possible solutions within financial order execution simulation software
  • employed machine learning algorithms for classification of x-ray scans
  • search algorithms to find specific range of data in binary file hierarchy

Databases                            

As a team we have worked with most of available databases including MSSSQL, Oracle, PostgreSQL, MySQL and Informix. We deployed databases both on in-house hardware and onto the cloud (Amazon RDS). We have created database setup scripts, stored functions and procedures, data export scripts to warehouses (Teradata). Yes, we also happened to implement business logic in SQL. We have developed database access code both on top of pure JDBC and object-relational mapping tools.

Build & Deployment                            

We are experienced with both heavy-weight enterprise deployment procedures, including corporate network and hardware sign-offs, and agile continuous deployment performed semi-automatically via CI tools. We have setup our own CI servers and tools and built deployment pipelines for whole product lines that included multiple client and API versions co-existing in production environments.
