Laravel backend developer at Ackuna building multi-tenant email campaigns with queued delivery and Amazon SES.

Ukraine

Message

At Ackuna, I design and develop the backend of a multi-tenant SaaS platform for managing large-scale email campaigns. I implemented tenant-level data isolation, Amazon SES tenant-based delivery, and asynchronous processing with Laravel Queues and Redis.

I also built campaign lifecycle and tracking features, SES webhook processing, and Stripe subscription workflows. I optimized PostgreSQL queries for high-volume data processing and improved email delivery reliability.

Previously, I worked on e-commerce, website-building, marketplace, and ERP products, including CGHARDWARE, GROOVE, TEN, and PUZZLE-DMS. My work has included third-party integrations, microservices, REST APIs, and backend performance improvements.
