At Rocket Firm, I designed and developed production Go microservices for Bereke Bank’s loan restructuring and credit holidays processes, defining service boundaries, PostgreSQL data models, and API contracts. I helped automate approximately 90% of workflow operations through Camunda-orchestrated banking processes.
I optimized a PostgreSQL query from 5 seconds to 300 ms and built REST/gRPC APIs and Kafka integrations with internal banking systems and external providers. I also implemented concurrent message processing with retries, dead-letter queues, and idempotency.
Previously, I developed Go backend services across Technodom’s e-commerce platform and loan and retail banking systems at Bank CenterCredit and Halyk Bank. My work included gift-card notification processing, product recommendation integrations, Camunda workflows, and Kafka-based communication.
