I’m a Software Engineer with 3+ years of experience building back-end services and systems in a microservices architecture using Go and Python. I focus on designing maintainable, scalable services with strong engineering practices.

At Iman, I built and maintained scalable marketplace backend services with Go, PostgreSQL, Kubernetes, and Docker using Clean Architecture and Domain-Driven Design. I owned the full lifecycle of the Budget App from architecture design to deployment and testing, and led a budget management microservice (Go + Gin) for expense and income tracking.

I’ve delivered measurable performance and reliability improvements—boosting reporting performance by 80% with PostgreSQL materialized views, reducing report query time by 80%, and engineering a Kafka-based webhook delivery system with a worker pool pattern that achieved a 98% success rate. I also synchronize order statuses using a concurrent cron job with Goroutines every 5 minutes.

Previously at AsakaBank and EPAM, I developed Python/Django backend features (including a Discord clone using MVT) and contributed to transitioning from monolithic to microservices. I also improved code quality with 87% unit test coverage and used concurrency to optimize database user loading functions.
