* Designed and implemented microservices system from scratch. * Supported CI tools, improved testing, code review, release and deployment processes. * Introduced product monitoring and alert notifications with Graphite and Grafana. I believe my main strength are: deep understanding how the whole programming stack works, from hardware, OS and compiler level up to framework and high-level code; focusing on domain and product, not just blindly follow the spec.
My main interest is backend part of some highload project. Standard benefits like public holidays, payed vacation, etc.

Have strong expertise in backend development (Golang, NodeJS) and application security. Love to deliver clean and maintainable software, thus fond of tests, CI/CD, code reviews and strict linters :) 1. Backend Engineer (Go) Worked on high-load, distributed social platform. Main stack - Go, Redis, Postgres, PubSub, microservices, gRPC/REST APIs, gCloud. 2. Application security engineer Performed penetration tests, secure code/architecture reviews. Provided full reports (OWASP ASVS) of both vulnerabilities and mitigations, assisted tech teams with fix implementations. 3. Backend Engineer (NodeJS) Worked on multiple short-to-medium sized outsourcing projects. Main stack - Node, Express, Mongo/Postgres. Leaded team of 4 developers. Performed task distribution, estimation, product delivery and customer demo.
- Wide tech expertise. If needed, I can write code in C++, Python, React in a reasonable amount of time. - Like to deliver supportable and high-quality code. Nevertheless, if necessary, can provide a quick and dirty solution - before all, the system must work as intended and bring value - Product-oriented mindset. Love to feel the impact and responsibility for my project.
Prefer product companies - high-load, microservice, cloud-hosted applications - NOT interested in the front-end development

1. Blockchain Framework - Rust Developer I was taking part in the development of a brand new Blockchain Framework. I was responsible for adding new features, optimizing existing code and participating in product development. 2. Blockchain Apps - Team Lead I was part of a small team of 6. I was responsible for: * coming up with architecture for apps * overall technical team performance * development, deployment and further service for our clients * communication with established clients, pitching company's products and services to leads (usually technical decision makers - CTOs, VPoEs, Team Leads etc) 3. Go/Rust Developer - Blockchain Trading Platform During this project I implemented a service which fetches unconfirmed data from the Ethereum blockchain, effectively "seeing the future" when compared to data possessed by exchanges. I have been responsible for the whole service and written it from scratch. * implemented a custom Ethereum protocol on top of devp2p * set up CI/CD using docker, gitlab-ci, consul and nomad * set up monitoring for the service with specifically crafted metrics with the help of Grafana + Prometheus * the project was 10% Rust, 90% Go

During my time as a Team Lead our team was at its peak performance in company's history. This is measured by the amount of successfully developed and deployed projects as well as by the capital brought by those projects.
Ideally, looking for a product company, where I will have an opportunity to dedicate myself to making a product better and company more successful.
