Full-Stack Developer

Designed and built a multi‑tenant CRM system for dental clinics from scratch. Tech stack: Vue 3 (Composition API, Pinia), .NET 7/8 (ASP.NET Core Web API, EF Core), PostgreSQL, Redis (caching, pub/sub), Docker, Nginx. Domain logic: Implemented appointment scheduling with conflict resolution, dynamic pricing rules, and role‑based access control for 5+ user types. Architecture: Applied Clean Architecture and DDD to keep the codebase maintainable as features grew. Operations: Deployed on Linux VPS, configured CI/CD via GitLab CI, automated backups and SSL renewal.

• System is used by 15+ active clinics, reducing manual admin work (e.g., reminders, invoice generation) by approx 40% according to user feedback.

Full‑Stack Developer

Worked in a team of 5 developers on a marketing analytics platform. Tech used: Nuxt 3, TypeScript, .NET Core, RabbitMQ, Redis, Docker, Kubernetes (basic orchestration), PostgreSQL. Migration: Assisted in splitting a legacy monolith into microservices (decoupled reporting, user management, notification services). Used RabbitMQ for async communication. Performance: Optimized slow API endpoints (added indexes, caching with Redis, lazy loading on frontend). CI/CD: Set up GitHub Actions pipelines for automated testing and deployment. Mentoring: Reviewed code of 3 junior developers.

• Cut average response time for dashboard data from ~800ms to ~350ms.
• Reducing release time from ~2 weeks to ~3 days.
• Helped two of them reach middle level after ~8 months.
