About
I am an Android developer with experience designing, building, and supporting native Kotlin applications used by thousands of financial-sector users. I manage full mobile lifecycles from analysis and development to deployment and ongoing support.
I also develop backend Java APIs and integrate systems to improve communication and delivery times, and I administer PostgreSQL databases while implementing ETL processes and reporting solutions with Hyperion BI, Power BI, and Report Builder.
I bring a pragmatic engineering approach that emphasizes performance, scalability, and user experience, and I’ve contributed to internal automation projects using Angular and Python to substantially reduce execution times and improve operational efficiency.
