Owned mobile delivery for Leap CRM end to end across iOS, Android and web—architecture, release process and production incidents. Cut the release pipeline from ~1.5 hours to ~10 minutes and shipped 158 production releases (76% of all releases) using staged rollout, a documented halt rule, and crash-rate gating. Built the pod from four engineers to eight and became removable via rotating release ownership and structured onboarding/OKRs. Led incident command for a 12-hour geocoding outage (92% request failures) and performed scoped remediation with root-cause analysis. Owned cloud estate architecture with a seven-phase consolidation plan across 87 keys, 40+ projects and six billing accounts; triaged 124 secret-scanning alerts across repositories. Authored release standards and org PII policy plus runbooks; owned a twelve-microfrontend decomposition plan and ran AI adoption with documented findings and guarded supervision.

Led Flutter development for Leap CRM including custom calendars, drawing tool, email composer, progress board, complex forms, role management, and real-time chat. Diagnosed and fixed a severe iOS storage failure (app consumed 97.94 GB) by shipping a kill-switch solution and validating via A/B testing on physical devices, reducing the image cache by 20–40%. Improved customer-facing response time from ~13 seconds to ~2 seconds. Served as de facto mobile release owner ahead of the formal role by making the case in writing, and contributed to production reliability work on a long-lived PHP/Laravel estate including query-plan and live-traffic issues.

Worked on client delivery studios shipping reusable app templates and client apps under the studio’s name. Contributed to multiple Flutter products delivered to App Store and Google Play, including features like video calling, payment gateways, live location tracking, and local databases. Provided client-facing support, handled issue resolution directly, performed R&D to keep the stack current, and wrote technical blogs.
