BronzeFull-Stack Engineer & CTO Consultant

1d ago

Full-stack engineer and technical lead with 10+ years building web products end-to-end. I cover the whole delivery cycle: architecture, backend, frontend, infrastructure, and the ML layer when a product needs it. Core stack: PHP (Laravel, Symfony), Go, Node.js, TypeScript/JavaScript, React, Vue, Next.js. Databases: PostgreSQL, MySQL, Redis, ClickHouse. Infrastructure: Docker, Kubernetes, CI/CD. APIs and integrations: REST, GraphQL, WebSocket, payment providers, CRM. I also build data and ML components: churn and scoring models (LightGBM, XGBoost, scikit-learn), data pipelines (ETL, Airflow), and analytics dashboards. Typical work: MVPs for crypto and fintech products, Telegram bots and automation, parsers and scrapers, API integrations, highload optimisation, legacy refactoring, code audits, and CTO-level consulting on architecture and team setup.
