Developer, AI engineer, and Senior QA/SDET, with about 20 years in IT. Looking for remote work or projects. Remote only.
Development: - Languages: JavaScript, TypeScript, Java, C#, Node.js. - Frontend: React, Vue 3, HTML, CSS. - I write services, tools, and utilities for the task, not just tests. AI: - Automation based on AI agents: I build working solutions and pipelines. - Fine-tuning of models using LoRA and QLoRA methods. Load and performance testing (separate direction): - Types of load: load, stress, spike, endurance, scalability, volume. - I look for bottlenecks, system limits, and degradation under load. - Tools: JMeter, Tsung, BlazeMeter, SAR (sysstat), RapidMiner, k6. QA automation (Senior SDET): - Autotests: Playwright, Selenium, Cypress, webdriver.io, Appium. - API tests, CI/CD integration (GitHub Actions, GitLab, Jenkins). - I build the entire testing infrastructure, not just write tests. English: I read documentation, but my conversational skills are weak. I quickly master new technologies and get to grips with other people's projects.
