Java Development

Developer

I started learning Java back in university in 2017. I really liked this language because it made it easy and convenient to build programs. I began studying popular frameworks and technologies, and at the end of my 2nd year of studies I landed my first job.

Over the years I've built a solid foundation across the full Java ecosystem — from REST APIs and ORM to message brokers and WebSockets — always working in the fintech and blockchain domain.

Java EE 95%
Spring Boot 95%
Spring MVC 90%
Multi Threading 85%
REST API 95%
ORM (JPA / Hibernate) 90%

Prometheus, Grafana, Micrometer 80%
JUnit / Mockito 85%
Swagger / OpenAPI 90%
Web Sockets 80%
IntelliJ IDEA 95%

Solidity Development

Developer

I started studying Solidity after 2 years of work. I was fascinated by how blockchain works and how smart contracts are written — I see a real future in this technology.

After learning EVM and the specifics of smart contract development, I started forking known contracts and studying their internals. A few months later I received my first real task: develop an ERC-20 token. That's how my Solidity journey began.

Since then I've shipped NFT marketplaces, GameFI projects, upgradeable contracts, and cross-chain deployments in production environments.

Solidity Core 90%
ERC-20 / ERC-20 Permit 95%
ERC-721 (NFT) 90%
ERC-1155 (NFT) 90%

ECDSA Signature (Auth) 80%
NFT Marketplace Development 90%
GameFI Development 85%
OpenSea / Rarible Integration 75%
Hardhat / Remix 90%
Ethers.js / Web3.js 85%
MetaMask & Contract Verification 85%

Server Infrastructure

DevOps

Questions about server infrastructure arose immediately after I started working. Difficult times require quick solutions.

I started by setting up CI/CD and Nginx, then moved on to Docker and further tooling. I found it very interesting — I wanted to understand not just the code, but how it runs on real servers. From that point I started performing DevOps tasks in parallel with development.

Bash Scripts 85%
Docker 90%
Docker Compose 90%
Auto Back-up Scripts (Postgres) 80%
Infrastructure Panel (logs, etc.) 75%
CI/CD (Jenkins) 85%
Grafana 80%
Postgres Admin Panel 80%
DigitalOcean Deployment 85%
Nginx Configuration 85%
Nginx Reverse Proxy 80%
SSL Certification (CertBot) 85%
