● Own the backlog for 3 workstreams — Payments, Compliance, Onboarding —
spanning 30 engineers across Android, iOS, web, backend, and QA; prioritize,
reorder, and decide what ships in every release.
● Sit directly across the table from business and compliance stakeholders to pull
requirements out of ambiguity, converting them into epics, user stories, and
acceptance criteria the engineering teams build against.
● Use AI agents — Claude, ChatGPT, and Copilot — to speed up compliance-
change documentation, cross-check requirement details, and support market
research for prioritization decisions.
● Shipped beta releases within 4 months of scoping, then staged rollout — 1%
for the first week, scaling to 100% within 10 days — to de-risk major releases.
● Sequenced feature rollout by market — starting in the US, then UK, then wider
Europe — pairing native and WebView implementations to hit time-to-market
targets without sacrificing platform depth.
● Diagnosed and fixed a sign-in flow issue causing user drop-off, lifting sign-in
completion to 80%, and delivered compliance changes within SLA to protect
both users and the business from regulatory exposure.
● Use Charles Proxy to inspect and verify API traffic across the Payments,
Compliance, and Onboarding workstreams.
● Keep one foot in the code: personally drove a 90% cut in production crashes
(20–25/week to 1–2/week) and a 20% cold-start improvement using
Perfetto/Systrace, Baseline Profiles, and App Vitals data — the same data that
now backs product prioritization calls.

● Developed customer onboarding and payment features for a banking client's Android app using the Backbase SDK, supporting 10 million users across Malaysia, Thailand, Indonesia.
● Customized Backbase SDK to meet biometric authentication, certificate-pinning, and session-handling requirements, passing security and compliance review.
● Improved onboarding completion by 10% and reduced drop-off through SDK integration optimization.

Bengaluru
● Facilitated all Scrum ceremonies — sprint planning, stand-ups, retrospectives,
backlog grooming — for a 20-person team split across 2 squads (Jan 2023 –
May 2024), owning the sprint backlog, work-item hierarchy, and clearing
cross-team blockers inside a SAFe program.
● Translated business and compliance requirements into epics, user stories, and
acceptance criteria for both squads on the Avaloq banking platform, and set the
architecture standards and coding guidelines both squads built against.
● Documented process flows and requirements for cross-platform feature parity,
then delivered shared business logic in Kotlin Multiplatform (KMP) so
Android and iOS behavior stayed consistent and traceable to a single
requirement.
● Reviewed engineering work for adherence to Clean Architecture and test- coverage standards as part of ongoing mentorship and quality gates.

● Delivered digital banking and payment features in Java/Kotlin for a regional
retail banking app serving customers across Southeast Asia.
● Shipped multi-language, localized UI so the app served customers across
multiple countries from a single codebase.
● Applied MVVM with strong unit test coverage, cutting regression defects and
improving release stability.
● Built core banking and payment modules on RxJava for async data streams,
consuming and parsing JSON from REST services.

● Built an MVP for a Dubai-based multi-school admissions platform, covering

diagnostic centers, including in-app delivery of diagnostic results.
