What I'm looking for

I want to lead mobile engineering roadmaps for fintech and health platforms, delivering secure, high-performance apps at scale. I’m excited to manage teams, improve reliability through QA and automation, and drive user growth and retention.

I’m a strategic senior mobile engineer with 7+ years of experience driving mobile transformation for Fintech, E-commerce, Healthtech, and SaaS organizations. I combine deep technical mastery of Java, Kotlin, and Dart with strong project management to turn mobile roadmaps into measurable user growth and retention.

In my recent work, I led development of DGePay Bekti & Saudagor apps, serving 10,000+ merchants and customers. I digitized sales transactions for 1,000+ retailers, reduced app crash rate by 30% with improved QA and proactive debugging, and increased merchant adoption by 25% by strengthening client relationships within 6 months—while maintaining PCI-DSS compliant payment operations with 99.9% uptime.

I also build across platforms and teams: at shurjoMukhi Ltd., I helped develop UNICEF’s Adolescent Health & Kala-azar tracking apps reaching 100k+ users, improved bug resolution cycles by 40%, and implemented robust offline functionality for low-connectivity areas. From mobile app performance optimizations to CI/CD automation, I focus on reliable delivery, secure payments, and high-quality engineering execution.
