Building core video editing tools for Instagram Edits (a standalone video editing app) on Android — real-time multi-track timeline editing, frame-level media synchronization, and complex gesture-driven interaction systems.

• Led the Android launch of video overlay — a foundational 0-to-1 editing feature — in 2 months, building the gesture and interaction system for multi-track editing and shipping infra that unblocked 10+ downstream features (cutouts, keyframes, opacity)

• Rescued a stalled headliner feature by reframing ambiguous requirements into clear design principles, aligning engineering and design on 50+ edge cases in 3 weeks after a 2-month deadlock

• Optimized the video player's seek pipeline to reduce seek latency by 3.4%, tackling frame-level rendering tolerance and decode-target synchronization — contributing ~20% of the org-wide quality goal

• Reduced app crash rate by 21% (top stability among competitor apps) by independently investigating and resolving 8 distinct crash patterns across the media rendering stack

• Led architectural refactoring of the real-time timeline state management system with zero regressions, and built developer tooling for concurrent state debugging adopted across the video editing org

Built creator-facing features and growth systems for Instagram Reels on Android, driving measurable creator engagement and content production.

• Delivered 6 projects in the first 10 weeks on the team, including the highest-impact creator recommendation feature of the half — ramping up with zero onboarding delay

• Designed and built a server-driven notification system for draft reminders, contributing nearly half of the team's quarterly creator activation goal

• Led a cross-team initiative (3 engineering teams) to build cross-posting between Facebook and Instagram, exceeding the creator growth target by 70%

• Identified and shipped a series of recommendation surface optimizations through independent data analysis and rapid experimentation, driving cumulative gains in creator engagement

Shipped user-facing features across Facebook Stories and Reels on Android, serving billions of daily users.

• Owned and launched music experience optimizations across Stories and Reels that accounted for 58% of the pillar's engagement gains — the largest individual contribution in the org

• Led the client-side migration to a unified camera SDK across Stories, Reels, and Feed, coordinating with 3 partner teams to modernize the camera infrastructure

• Built and shipped 6+ features end-to-end — from Stories Archive and Close Friend Badges to Reels recommendation surfaces and Page Reels creation — managing experimentation and global rollout independently

• Improved music content discovery by building a smart prefetch system that reduced picker load time by 31% and increased response rate by 63%

• Ranked 3rd out of 175 engineers in an org-wide code quality sprint, shipping 47 fixes in 2 weeks

Team: Louhi, Google Cloud EngProd

• Launched survey, attended brainstorming and review meetings, created UI mock-ups for welcome page and release metrics page in Louhi (A release orchestration tool).

• Created web components for metrics cards with Polymer 3, LitElement and Google Charts.

• Designed REST API including endpoints and responses for metrics microservice.

Team: Unity Connect

• Developed front-end of the live page for Unity Connect website using React and Cerebral frameworks. Unity creators can now showcase their expertise, experience, and inspirations using the live page.

• Refactored back-end codes with interface with Go Language, including web service and API.

• Optimized the operating environment of application based on Kubernetes (a system for deployment and management of containerized applications).
