Hej!

Bio

Business

Most of the time I’ve worked as a contractor, because the balance of interest/compensation/freedom usually shifted against me, however theoretically it’s not a rule.

A long time ago I was a freelancer, doing some web development, maintaining cryptographic gem, doing proof-of-concept implementations, tutoring general topology, and even writing educational articles about basic cryptography.

With some background in mathematics and cryptography, it seemed quite straightforward to get into in the newly emerging blockchain sphere.

In 2017 I worked in an ICO startup (in the end it failed), there I was creating smart contracts, writing the whitepaper whitepaper, pitching the project at conferences (d10e conference in Seoul), organising the workflow, dealing with customers.

Then I participated in a research/working group for another blockchain project which was built on BitShares which used the then-unknown DPOS consensus.

In 2019 I worked as a blockchain developer at dexpa.io, porting Ethereum smart contracts to the TON blockchain.

Later, in 2019-2020, security analyst at FutureComes, making security audits for web and crypto projects (wallets, exchanges and exchange services).

I was involved in the Handshake project, with tiny contributions to the node and the protocol. I've built a web wallet for it, and a block explorer.

In 2021-2023 I was mostly doing Ethereum-related development. For example, we launched speculative NFT projects: Exponentials, Logarithms; mined gems on GPU with CUDA; wrote code to participate in overhyped onchain sales (when MEV had not yet been a thing); mimicked human interaction for web platforms and tried my best with some open cryptography problems, however with no results..

In 2024 implemented stateless DANE TLS scheme for Handshake: repository, its short presentation.

In 2025 I contributed to the Spaces protocol: public-key infrastructure and digital identity anchored to bitcoin. There I made a block explorer and secondary market

Also atbitcoin website and Nacho mobile app. I was also responsible for DevOps part of the projects.

I'm open to interesting proposals!

Academic and educational

I have academic bacground in mathematics and computer science (general physics as well).

Graduated from the Belarusian State University with specialist degree thesis: the density of Cartan subalgebras in the variety of abelian subalgebras of complex semisimple Lie algebras. Then I spent a year on master’s programme in mathematics at HSE faculty of mathematics with term paper topic: structure of the automorphism group of a finite-dimensional associative algebra.

In 2022 I finished Master’s in Mathematical Logic and Foundations of Computer Science at University of Paris. My master’s paper is about algorithmic randomness (supervised by Alexander Shen).

I’ve also taken a few courses at Independent University of Moscow and follow some mathematical and natural science courses from Collège de France.
