I'm Kabir — I ship reliable, high-scale Android products. Currently keeping 1.5M+ daily users on CarInfo crash-free at 99.99%.
A developer who cares about what users feel.
I'm a Software Developer with 3 years of experience across the full Android lifecycle — from architecture and modularization to the last 1% of crash-fixing that keeps an app trustworthy at scale.
At CarInfo, I help maintain apps used by 1.5M+ people every day, where I led app-wide modularization, drove a server-driven UI architecture, and pushed our crash-free rate to 99.99%. I'm equally comfortable in the backend with Java Spring Boot.
Where I've shipped.
- Developed and maintained the CarInfo & BikeInfo Android apps serving 1.5M+ daily active users, reaching a 99.99% crash-free rate and cutting out-of-memory crashes by 62% (resolving 3 of the top 5 crash issues).
- Led app-wide modularization — splitting network, database, payments and deep-link handling into independent modules, improving maintainability, build times and scalability.
- Built a server-driven UI (SDUI) architecture to render homepage components dynamically, reducing dependency on frequent app releases.
- Introduced Jetpack Compose reusable components and migrated homepage sections from XML to Compose.
- Built and maintained document-editing apps with over 1M DAU at a 99.5% crash-free rate.
- Analyzed user behavior through Appmetrica to find bottlenecks, leading to a 15% increase in user flow.
- Integrated Kotlin & Firebase into new apps and migrated legacy Java codebases to Kotlin, improving code quality and maintainability.
- Developed an open network platform for retail sellers as part of ONDC (Open Network for Digital Commerce), contributing across the full product lifecycle.
- Launched the MVP successfully and analyzed early user feedback to refine the product for a broader launch.
