Contributed to REST API development for a polling platform using Laravel, Symfony, and Python, along with integrating AI-powered features into backend services and IaC for AWS (SQS, SNS, Lambda, Terraform).

• Managed large-scale platforms and expanded technical expertise across JWT, OIDC, OAuth2, and Filament, while applying LLM integration, prompt engineering, and RAG-based solutions.
• Led the migration from Redis Streams to RabbitMQ for asynchronous processing, addressing consumer group limitations and failure recovery. Designed production-grade messaging with DLQ/DLX, controlled retries, and idempotency guarantees, plus monitoring for throughput and backlog.

Ekar is an on-demand mobility platform providing access to a network of thousands of cars bookable via the Ekar App.

• Engineered microservices from concept to launch and re-engineered critical modules for performance and scalability across AWS (EC2, S3, RDS, CloudWatch, SQS, SNS, CodePipeline), RabbitMQ, and RPC.
• Designed and operated a Wallet microservice with high-sensitivity transactional APIs: strong consistency, atomic balance updates, idempotent operations, and strict validation to prevent double execution.
