What I'm looking for

I seek a hands-on role improving mobile platform stability and developer productivity, with opportunities to lead automation, architect scalable systems, and collaborate with product and engineering leaders.

I am a mobile-focused software engineer with deep experience in Android engineering, Kotlin Multiplatform, and platform reliability. At Accenture I led product developer support, drove open-source contributions, and established PR workflows that improved team delivery.

I build scalable mobile and web products end-to-end: from a high-throughput B2B ordering Android app processing ~2,000 daily orders to a secure non-custodial cold wallet for the XRP Ledger. I emphasize crash-free stability, robust encryption, and automated deployments to minimize downtime and manual work.

I deliver operational improvements and automation—AI-driven issue summarization, automated RCA generation, a metrics pipeline generator that cut processing time 75%, and Firebase template automation—helping teams migrate faster and save hundreds of engineering hours.
