I contributed to building top-tier infrastructure for the Solana blockchain.
SNS allows users:
– Create a human-readable identity by replacing wallet addresses with domain names.
– Share and use domains almost everywhere in the Solana ecosystem (Phantom, solscan, Brawe Wallet, etc) due to 60+ integrations.
– Trade, transfer, NFT their domains in many different ways – directly on the website, mobile app, SDKs, and public APIs.

Core Responsibilities and Achievements
– Led the design and development of key functionalities across frontend, mobile (React Native), and APIs in an environment with minimal predefined requirements that involved making independent and important decisions. Integrated blockchain-related functionality on both the client and server sides. Performed integrations with partners' services.
– Promoted, implemented, and maintained tools that improve DX for the internal team (CI, Sentry, Storybook, documentation, knowledge-sharing sessions) and open-source contributors (SDKs, public APIs, Discord channel, interactive demos for libs). Implemented internal and open-source libraries and SDKs.
– Had full responsibility for the frontend part and mobile app over the last few years.
– Led code refactoring and development practice initiatives, including:
Performance optimizations. The website became almost two times faster, and almost fully green in terms of metrics, due to improved resource loading, fixing important Web Vitals metrics, and enchased project architecture. This was very difficult to achieve due to the heavy dependence on third-party, poorly optimized libraries;
Better errors handling. By changing errors management in the codebase, and adding monitoring and reporting tools, we achieved almost zero user-reporting bugs without any dedicated QA team.

The project's mission is to be a social network that will be fully resistant to censorship. Part of the functionality is based on one of the most popular (one of TOP 5) blockchains to provide users the ability to use the most-wanted crypto features (trade, NFT, secure wallets, etc). Another part, which provides censorship resistance, is a P2P network such as BitTorrent, so there is no data stored on any node – users themselves are nodes.

My responsibilities:
– design and develop frontend system;
– design and develop components library;
– integrations with partners' services;
– integration of blockchain-related functionality;
– product improvements and marketing discussions;
– UI/UX discussions with the design team;
– organize development process (CI/CD, testing, releases, branching, etc);
– code-review, knowledge-sharing sessions, newcomers onboarding.

The company name is hidden because the platform being developed is a censorship prevention tool, so the team wants to remain anonymous for as long as possible.

AirGrid is an audience platform that allows advertisers and publishers to operate on the privacy-first currency in the open marketplace.

My responsibilities are:
– develop from scratch the full app interface (dashboards, charts, generic UI components, and more);
– discuss UI/UX improvements with the team, and then implement them;
– write unit tests, integration tests, perform code reviews, mentor devs;
– refactoring the existing code base to make the system much more scalable and code-friendly;
– implement business logic on the backend.
