Dmitrij Rysanow
Senior Fullstack Developer with 10+ years of commercial software development experience. Specializing in Angular and TypeScript, with backend development in Node.js (Express, NestJS). Experienced in application and API architecture, legacy modernization, performance optimization and building scalable, secure solutions across the full stack — from UI through APIs and data access to CI/CD and cloud.
Core Strengths
Enterprise-grade Frontend Systems
Design and development of large-scale, enterprise-grade frontend systems in Angular or React. Fast at picking up new — even lesser-known — frameworks and adapting to each project’s stack, constraints and domain. Focus on performance, scalable architecture, efficient state management and long-term maintainability.
Communication is Key!
Clear, proactive communication treated as a core engineering skill. Strong focus on validating and clarifying requirements up front so the delivered solution matches what the client actually needs, and on aligning with each project’s standards, conventions and ways of working. Comfortable in Agile/Scrum teams — sprint planning, estimation, code reviews and continuous stakeholder feedback. Structured communication and reporting using the STAR methodology (Situation, Task, Action, Result).
DevOps & Cloud Delivery
Design and operation of CI/CD pipelines and cloud-native delivery. Hands-on with GitLab CI, GitHub Actions and Jenkins, containerization (Docker), orchestration (Kubernetes) and infrastructure automation. Experience across cloud platforms (Azure, Google Cloud), with a focus on reliability, scalability and repeatable, automated deployments.
AI Tools Understanding & Usage
Practical, hands-on adoption of AI-assisted development. Daily use of GitHub Copilot for coding, refactoring and code reviews. Building custom MCP (Model Context Protocol) integrations to connect AI agents with project-specific tools and data, plus a mobile AI-agent toolkit (an AI agent app on the phone). Strong focus on the safe application of Human-in-the-Loop in operations — keeping a human in control of critical actions and decisions.
