Software Developer

Reduced Weni’s startup time from 15+ seconds to under 2 seconds through React Native performance improvements, caching, version-aware loading and API cleanup.
Built mobile and backend features for Ondi, a logistics platform. Improved app lifecycle and authentication handling so active drivers were less likely to appear offline.

Selected projects

LeadOS

Built LeadOS end to end: an AI system that helps sales teams assess potential customers, with a public website, staff dashboards and backend.

AI handles voice and chat conversations using business documents for context. When a call ends, it triggers analysis to assess the customer’s interest and readiness, then prepares a summary and next steps for the sales team.
