• Led backend and cloud initiatives in the Ordering/Checkout domain at Eventbrite, focusing on large-scale Ticketing and Ordering infrastructure, actively participating in cross-team projects.

• Modernized CI/CD and AWS architectures, enhancing reliability and observability for critical purchase flows.

• Drove cost optimization and production readiness, improving system resilience and customer experience.

• Developed E2E test coverage for web and mobile platforms, ensuring high-quality deliverables.

• Joined the Ordering team and focused on building reliable, scalable, and cost-efficient platforms, successfully transitioning from PHP development stacks to Python environments with gRPC and RESTful APIs over AWS Lambdas, AWS Fargate, and building pipelines and infrastructure with Terraform and CircleCI that was later migrated to CDK with CodePipelines and CloudFormation. The main goal was to transition and break down the Core monolithic legacy system into microservices in a distributed system that resulted in the creation of 8 new microservices under the team’s domain.

• Worked on enabling the gRPC communication with the Legacy system by implementing the first gRPC server that allowed the connection with the new microservices.

• Developed Python, Kotlin, and TypeScript clients to facilitate the gRPC integration between the legacy systems and the new microservices.

• Participated in on-calls, operational excellence, and deployment automation by provisioning pipelines.

• Integrated monitoring, alerts, notifications, paging, and the building of dashboards with AWS CloudWatch, Sentry, and Datadog.

• Designed, developed, and delivered a full-stack web Minimum Viable Product platform with a Vue.js (Vuex, Vuetify) front-end and a RESTful API backend.

• Implemented CI/CD pipelines using Bitbucket Pipelines, Docker, and AWS ECS Fargate, ensuring scalable and automated deployments.

• Applied Domain-Driven Design with CQRS and Event-Driven architecture, using an in-memory and database-backed event bus for asynchronous task handling such as video trimming, snapshot generation, and LinkedIn profile crawling.

• Built and maintained API documentation and mock servers via Postman, integrated JWT authentication, and implemented robust testing suites with PHPUnit, Mockery, and SQLite. Delivered multiple third-party integrations (Twitter, Stripe, Firebase, LinkedIn, Twilio, Agora).

• Developed an AWS Lambda-based image resizer service for efficient media processing.

• Contributed to the migration of legacy systems to a modern Symfony-based monolith (PHP-based framework), improving maintainability and scalability.

• Designed and maintained the company’s core search engine, leveraging Elasticsearch and Redis for optimized query performance.

• Developed and maintained RESTful APIs for third-party integrations and built internal services to consume external APIs such as Facebook, Google, and Twitter.

• Implemented a custom analytics and tracking system using MongoDB, and upgraded major infrastructure components to newer versions to enhance performance and security. Modernized the front-end stack by migrating from AngularJS + REST to Vue.js + GraphQL, and adopted Domain-Driven Design with Event-Driven architecture powered by RabbitMQ.

• Ensured high code reliability through extensive unit testing with PHPUnit.
