● Led subscription management rewrite with unified billing state machine and shipped via phased A/B rollout, cutting billing renewal incidents by 50% and slashing involuntary churn from 9.4% to 4.5% for 688K subscribers within 6 billing cycles. ● Authored an RFC to set companywide standard for date and time, published a library adopted by 20 engineers, standardized time zone conversion, eliminating recurring date and time bugs with zero regressions since Jan 2024 per bug dashboards. ● Architected a location library adopted by 5 teams, accelerating integration time from 1 day to under 1 hour measured by average time to first successful call, and improved location resolution success by 10% for location-based pricing.

● Architected a redesign of the Bluetooth Low Energy transfer stack and drove the RFC process to deliver a state machine with persisted session recovery, optimizing transfer completion and halving reconnect-related failures across 20k sessions. ● Deployed an in-app media-guided COVID testing flow, cutting mid-flow abandonment by 30% across 5k monthly sessions. ● Migrated three mobile app architectures into a single MVI standard incrementally over 6 months, driving adoption across 10 engineers. Accelerated onboarding by removing architecture ambiguity and increased unit test coverage by 10%.

● Designed and developed a Kotlin Multiplatform Mobile platform framework providing standardized data access, design system, navigation, and location, reducing feature delivery effort by 3 times across an 8-person team in 4 repositories, reducing duplicated infrastructure work and improving reliability. ● Developed and scaled mobile release automation for 5 apps by standardizing the release workflow with Fastlane, cutting weekly release overhead from 30 minutes to a single command and decoupling the release process from the CI vendor to keep it portable across systems. ● Established an Android critical fix rollout process using in-app updates and push message controlled feature flags, reducing rollout time from 14 days to under 24 hours and improving crash-free sessions from 94% to 99% for the 20 largest enterprise clients in Azerbaijan. ● Mentored 10 engineers for 2 years through structured weekly guilds and architecture workshops, contributing to 3 promotions to senior level and accelerating adoption of modern Kotlin and MVI standards across the organization.

● Led a quarterly inventory process transformation from manual counts to RFID scanning. Owned RFID vendor selection and integration, deploying to 10 large enterprise clients including Pasha Bank, Azerbaijan's largest bank, cutting inventory taking time from 2 hours to under 5 minutes and eliminating count discrepancies. ● Implemented and rolled out a local caching and delta sync architecture to reduce redundant network calls, driving a 40% drop in network costs while maintaining data freshness and integrity. ● Designed and implemented an Android idle time sync architecture as a shared app-wide layer, cutting user data wait latency from 2–5s to under 0.5s and slashing slow data support tickets by 96%.

● Led delivery and launch of a carpooling MVP app in 3 months, reaching about 1,000 daily active users in 6 months and reducing commuter out of pocket costs by about 50% versus public transport. ● Shipped in-app instant messaging for ride hailing, increasing shared-ride completion rate 20% over 2 months post-launch in the same control cohorts by reducing pickup and coordination failures.
