• Built and maintained full-stack features end to end with React/Next.js and NestJS, developing and integrating RESTful and GraphQL APIs across multiple projects.
• Implemented backend business logic and data access on PostgreSQL, MongoDB, and MariaDB, using Redis caching to reduce database load and speed up responses.
• Developed and maintained services in CQRS-based microservices architectures, separating read and write models to keep business logic modular and maintainable.
• Built asynchronous messaging between services with RabbitMQ to decouple workloads, and shipped changes through automated CI/CD pipelines.
• Troubleshot and resolved bugs across frontend and backend components, tracing issues to their root cause before applying fixes.
• Used AI-assisted tools to speed up code reviews and test generation, reviewing and validating every AI-generated suggestion and test before merging.

• Developed features for the company's product with React/Next.js and NestJS, backed by PostgreSQL, MongoDB, and Redis.
• Built and integrated RESTful APIs connecting frontend features with backend services.
• Wrote unit, integration, and end-to-end (E2E) tests to validate application behavior and catch regressions early.
• Worked in Agile/Scrum sprints (planning, daily stand-ups), followed GitFlow, and took part in pull request reviews.
