Experience

Currently i'm involved in a research and development of a blockchain DApp. The DApp is a PoC for a platform which main purpose is to automate deployment of different blockchain nodes and abstract interaction with them.

Responsibilities:
- design and development of the DApp;
- code review;
- research.

Methodologies:
- Kanban.

Technologies:
- Java 8;
- Keycloak;
- Maven;
- Golang;
- gRPC;
- MongoDB;
- Smart contracts;
- Self-Sovegeign Identity;
- Docker, Kubernetes;
- GitLab CI/CD.


During my second employment i was a part of an Artificial Intelligence department. In small decentralized team of researchers we developed a scoring subsystem for the platform and designed a framework for deployment and orchestration of different types of ML-models.

Responsibilities:
- design and development of RESTful services;
- introducing ML-algorithms (research, implementation, training, validation, integration).

Methodologies:
- Kanban.

Technologies:
- Java 8;
- Spring Framework (Boot, Integration);
