TOPASS tokens provide a unique safeguard against the possibility of counterfeit goods with single-package accuracy. The consumer will be able to verify the originality of the product immediately after purchase.

Security with TOPASS tokens prevents copying and multiplication of security features on counterfeit products, which is possible with hologram security features. There are many other uses for TOPASS tokens, which are described on the website.

The TOPASS smart contract runs on a public blockchain platform. We use the efficient L2 Polygon platform for this purpose. It guarantees high performance and low transaction fees. We can run our smart contract on another Ethereum-compatible platform upon your request.

I was in charge of implementing NFT tokens and modifying them for client requirements. I also programmed a middleware server using Node.js and Express.js, which provided a REST API to enable the client systems to use the tokens.

The S3DOC information system is a new generation of a durable medium with digital signature (eIDAS), the so-called softWORM, in which durability features are guaranteed by applying the best world practices and standards in the area of algorithms and cryptographic methods implemented in the software. S3DOC is an innovative EU-wide information system with the characteristics of a durable medium.

I designed and developed the S3DOC durable medium based on Ethereum and IPFS. I created complex smart contracts, e.g., data storage, user management (user register, personal data, authentication), and document management (document register, document metadata). I built decentralized software that stores documents on IPFS and their metadata on Ethereum. In the second version of the system, I moved all the software to a new blockchain platform written in Node.js, achieving much better performance and security compared to Ethereum and IPFS.

A proprietary blockchain platform designed for enterprise corporations. The platform provides the highest level of security and performance. It is designed to store large volumes of data, run smart contracts, create performance and reliability clusters, and use zero-knowledge-proof procedures to secure data. The platform is written in JavaScript and runs in the Node.js environment. It has a modular design, where each module is responsible for its technological features, e.g., the P2P module manages communication between nodes of the blockchain network.

Seeing the limitations of the Ethereum platform in enterprise applications, I proposed to create a new blockchain platform from scratch with the high performance and security levels required by large financial institutions. I designed the architecture and developed the core modules of the platform.

A micropayment platform that enables pay-per-content billing. The user creates a prepaid account and buys tokens to pay for access to digital content such as portals, newspaper articles, movies, and blogs. PENNYCUT operates on a blockchain platform.

Unit-test-script-generator is a tool that allows developers to quickly prepare scripts for unit tests running on popular frameworks such as Jest and Mocha. The package is available on the npm platform and is entirely prepared in Node.js and JavaScript. The package can be used to test smart contracts.

Developing software that runs on the blockchain platform usually requires the creation of a smart contract and a back-end program to interact with it. This package allows users to generate an API library based on their ABI configuration for the smart contract. After calling the generator, users will get a complete library to interact with all the functions in the smart contract. The generator was written in TypeScript and is available in the npm repository.

A mobile application dedicated to S3DOC users. The app allows you to access documents stored on persistent media, view them, and review the history of events. The application supports push notifications about new documents and also supports biometric login. It works on Android and iOS platforms.

Renderers are used to support the unique properties of the operating systems.

The application supports a secure REST API.

An application that allows access to the Intrack system data. It is characterized by an advanced UI and many charts. A .NET library was created specifically for this project to draw animated charts.

The application runs on Android and iOS. Renderers are used to support the unique properties of the operating systems.

The application supports a secure REST API.
