I am a Software Engineer (Backend — Go, TypeScript) with domain knowledge in FinTech, DeFi and e-commerce.

• Now I work at Blum in Telegram Mini App team. I am directly responsible for a wide range of TMA features and my work contributes to fair & responsible trading experience for crypto 😊

• Sharded a 1TB monolithic database into 24 shards without downtime.

• Acquired quite a strong expertise in professional optimization. Specifically, I've optimized gRPC handlers and Kafka consumers/producers. Either by low-level methods (pprof, metrics, etc.) or by refactoring architecture to eliminate bottlenecks.

• I created and designed algorithmic copytraing system for a Base Chain (chain id 8453).

• Deployed 2 blockchains from scratch - bootnodes, light-node and RPC EVM nodes on the base of AWS EC2 machines.

• I always loved to bypass antifrauds and begin career in tech based on that. However, my dream basically came true and I've created an antifraud from scratch for Avito - largest classifieds in the world. Specifically, I'm responsible for hardcore research, design review, and implementation of antifraud of ~50%+ payment traffic.

• Throughout the years, I've became pretty good at the so called DevSecOps - you can check out my linked in to see the work in this sphere. Honestly, I believe this is what every developer had to do.

However, besides job stuff I feel like I actually deeply love what I'm doing :)

• I kind of share the philosophy of Primigean - the more you do something, the better you get at it, the more interesting it is to do it. I was lucky I had 0 'boring' projects ever, maybe besides a few very first educational ones (coding decimal library in C11 decimal.h with bit-shifts was a bit boring, but actually I've used decimal type every day at crypto. I think this is Karma 😁)

• TJ, especially his PDE Talk and tutorials ~3 years ago inspired me to give NeoVim a chance. Since that I'm a happy user of Neovim. I definitely can appreciate other editors, but NeoVim is just so good/extensive (and I also like what the team is doing with architecture, RPC protocol, etc.), that I see no reason to change.

• POV: I'm on my third coffee and you just asked me how the internet works

• I have gave Nix & NixOS a fair change for 3 weeks, but I'm not sure they actually solve problems they actually solve problems they claim to solve. (maybe I missed proper intro by @alurm, who knows..)
