PROFESSIONAL EXPERIENCE
2019 - 2023 Azul Systems
https://www.azul.com/
Position: senior software engineer

Participating in the Zing (Azul's JVM) related subsystems:

- ReadyNow - preloading JVM's objects (classes, methods, ...) that were
actually loaded on the previous run of given application. That
significantly accelerates the current run of this application.

- Claud Native Compiler is when the JVM sends its hottest
(most often called) methods to "compiler Web server" which performs
actual compilations of these methods and sends object files (result of
the compilation) back to JVM.

- Code Cache is when previously compiled methods are taken from some store
(cache) instead of compiling them again.

2018 - 2019 OOO AIRT
https://www.rusprofile.ru/id/2517148
Position: software engineer

- Protection Windows native applications from unapproved use,
- Protection of JVM applications from unapproved use.
- Modelling some aviation devices.
- Visualizaion of aviation charts

CPosition: principal software engineer

Main concern is bugfixing, refactoring and implementation of new
features of Sun/Oracle C++ compiler.

In particular, the following C++11/14 features have been
implemented:

- rvalue references,
- move constructors,
- initializer lists,
- auto typed variables,
- member initializer and aggregates,
- propagating exceptions,
- contextual conversions

Other implemented features:

- exception handling under the C++ Itanium ABI
- zero-length arrays
- restricted pointers
- gcc inline assembler
- a few gcc attributes.

1994-2005 Transas Marine (This is Wärtsilä for now)
https://www.wartsila.com/

Position: Leading software engineer

Experience/concerns:

- Participating in developing embedded marine/aviation navigation
systems.

- The software package for installation of company’s software
products (several generations). It includes control of specific
data of the Transas Company (electronic charts, licenses and
so on).

- Libraries (several generations) for protection of the software
products and specific company’s data from unauthorized operations
(hacker attacks). It includes programming (and microprogramming)
of electronic protection keys (dongles) Sentinel SuperPro,
Activator/M, Guardant Stealth.

- Program for visualization and installation collections of
electronic charts (catalogue). It is a part of some navigating
products of the company. Transas/Wärtsilä has been using this software
till now:

product of company.

- Applet for visualization of electronic charts in the Internet
(support).

1993-1994 The Small State Enterprise "InfoService"

Position: Leading Software Engineer

Developed the multy-purpose archiver AIN. The software product in its
working characteristic (quality of compression and speed) outperformed
the most of the well-known analogs (ARJ, PKZIP, etc.).

Languages: Assembler (3,500 lines) and C (3,800 lines).
