About

I'm a Senior software engineer with a strong frontend/design foundation and extensive experience owning end-to-end product features. Specializing in bridging technical architecture and product delivery, I drive initiatives from concept to production across frontend and backend systems. Beyond writing code, I also lead high-priority features and projects, navigate technical trade-offs, and ensure solutions are scalable, maintainable, and aligned with business and stakeholder goals. Core expertise: - End-to-end ownership: Driving features across the full stack (React, Python, Django), from requirements and architectural design to deployment and iteration. - Technical leadership: Leading cross-functional initiatives and feature teams to deliver high-impact work with strong engineering standards. - Architectural decision making: Designing APIs and frontend systems that balance immediate business needs with long-term system health.
