Dmitrii D.

I build and maintain production web applications end-to-end: frontend, backend, databases, integrations, AWS infrastructure, deployment, and the operational tooling needed to keep them reliable after launch.

I have 20+ years of experience in software engineering and more than 10 years focused on full-stack web development. I work comfortably across the entire stack, take ownership of production systems, and can work independently with an existing design, codebase, or product.

◆ Current Project: UK Affiliate Platform

I currently develop and maintain a production affiliate and deals platform as the sole developer, with responsibility for the complete technical implementation. The platform started from a Figma design and now includes:

• Responsive frontend and UI development
• Backend APIs and business logic
• PostgreSQL database architecture and data workflows
• AWS infrastructure and production deployment
• Third-party API integrations and automated imports
• Admin dashboards and internal tools
• Email and user engagement workflows
• Analytics, monitoring, SEO and performance optimization
• Production debugging and ongoing maintenance

My role goes far beyond building pages. I handle the full path from product requirements and implementation to deployment, infrastructure, maintenance, and production troubleshooting as the platform continues to evolve.

◆ What I Work With

• Node.js, NestJS, TypeScript and JavaScript
• React, Angular, Vue.js and Nuxt
• HTML and CSS
• PostgreSQL, MongoDB and Redis
• REST APIs and third-party integrations
• AWS, Docker and production deployment
• Responsive and accessible user interfaces
• Admin panels, dashboards and complex business workflows

◆ Production Experience

I have extensive experience with long-lived production systems where reliability and maintainability matter as much as shipping new features.

For approximately 10 years, I worked as part of a team on a large UK event-management platform, building and maintaining frontend applications, APIs, business workflows, integrations and internal tools.

My earlier background in QA and formal verification still strongly influences how I develop software today. I pay close attention to edge cases, regression risk, predictable behaviour, testing and production reliability.
