• Led frontend mobile development of a production EV charging consumer app serving real-time session workflows,
collaborated with technical Leads and CEO for Feature Enhancements for distributed charging infrastructure.
• Built 25+ React Native screens with modular component architecture reduced feature delivery cycle time by 40% through
reusable design patterns and shared state abstractions.
• Chose WebSocket for low-latency bidirectional session state and MQTT for lightweight pub/sub presence across 25+
stations combined with RabbitMQ for reliable async event queuing eliminated message loss under intermittent
connectivity.
• Engineered offline-resilient session recovery that detects network loss, queues state mutations locally, and reconciles
with server on reconnect
• Maintained 98.8% crash-free rate (Firebase Crashlytics) triaged and resolved 3 critical production session-drop
regressions within 48-hour SLAs — primary on-call for mobile reliability in a 6-engineer team.
• Owned the full frontend delivery lifecycle - architecture decisions, code review, Firebase monitoring, and cross-functional
coordination with backend and product.

• Built a multi-branch POS SaaS platform handling orders inventory state, and centralized operations across branches
— first production experience shipping user-facing transactional flows.
• Designed real-time revenue and margin dashboards using FastAPI + Supabase replaced manual reporting with
automated analytics, saving 8 hours/week of manual work for operations staff.
• Identified N+1 query patterns in branch-level reporting APIs and optimized with aggregated SupaBase views reduced
dashboard load time from 4s to under 800ms.
