Work experience

Senior associate

from 11.2023 to 11.2025 (2 years)
Andersen, Remote (IT)

Built a customer-facing analytics SaaS serving ~18k monthly users, developing the frontend with React/Next.js and adding server-side rendering (SSR) to improve SEO and reduce initial page load times.
Migrated a legacy PHP reporting backend to NestJS (TypeScript) with PostgreSQL, optimizing queries, adding indexes, and resolving long-running requests under peak traffic.
Developed internal admin tools with Vue.js, enabling operations teams to manage and update data without manual spreadsheets.
Designed and maintained REST and GraphQL APIs for web and mobile clients, ensuring backward compatibility, handling breaking changes, and managing staged rollouts.
Improved system performance and reliability by adding Redis caching and background processing with RabbitMQ, reducing synchronous request failures during traffic spikes.
Deployed services on AWS (EC2, RDS, S3) and later containerized with Docker and Kubernetes, resolving autoscaling and health-check issues in production.
Established CI/CD pipelines using GitHub Actions and Jenkins, reducing deployment errors and rollback times to under 10 minutes.
Built a nightly data synchronization service with FastAPI (Python), storing results in PostgreSQL and Elasticsearch to support reporting without impacting production traffic.
Optimized PostgreSQL and MySQL performance using connection pooling, read replicas, and query tuning, reducing p95 latency under load.
Applied Domain-Driven Design (DDD) and Clean Architecture when decomposing a growing monolith into smaller services, improving maintainability and developer onboarding.
Mentored junior full-stack developers through code reviews, pair programming, and architecture guidance, improving code quality, delivery speed, and team best practices adoption.
