Hi there, I'm Alex 👋

I speak Data Structures & Algorithms, English, German, Russian, French, Italian, Spanish and some Chinese.

I am fluent in TypeScript for Node.js/Nest/Express/Fastify and React/Next.js. Angular/Universal, Vue.js/Nuxt.js. Python for Django/Flask/FastAPI. Go for gin/echo.

I also speak Rust for:

• WebAssembly
• Warp / Actix / Rocket
• Ethereum with openzeppelin (Solidity/Vyper, foundry/truffle/hardhat):
  • Arbitrum with stylus
  • Reth for L2 Optimism / Polygon / Binance Smart Chain / StarkNet etc.
• Solana (with mucho, anchor, fuzz, zest)
• Aptos (move SDK)
• SUI
• Fantom
• Flow
• Near
• Polkadot
• TON (Telegram Open Network)
• extensive expertise in Telegram bots programming

React Native/Expo and Flutter (Kotlin and Swift in progress) are my go-to for mobile development.

I am in a love/hate relationship with C/C++ and FreeBSD❤️. When I feel particularly nerdy I code Haskell and Lisp, play chess, spend a lifetime on Leetcode/HackerRank leveling up my score and kitesurf in Alps (Cabrinha Contra 17).

I am fluent in DevOps/Gitops dialects, Docker/Kubernetes/OpenStack, Ceph, OpenTelemetry, IaC and all around it. I enjoy working with Terraform & Ansible in AWS and GCP environments.

I am a developer, technical consultant and ex-CTO with over 15 years of progressively challenging technical successes in diversified, cutting-edge technologies with demonstrated and proven ability to organize, train and lead cross-functional teams in achieving superior results, making me a team player and a leader with a strong sense of responsibility.

I code everything that can be scripted, compiled or used as a microservice or a blockchain smart contract and lead teams to do the same.
