Case Studies
Company-safe examples of how I work
I have not centered this site around personal projects because my strongest work has come from shipping real products in real teams. These case studies focus on ownership, constraints, and outcomes without exposing confidential details.
PayPal
Campaign workflow architecture & management platform
2025 – Present
- Context
- PayPal's campaign management system needed a complete V2 rebuild to support growing team scale, complex approval workflows, and high-throughput API requirements.
- Problem
- The existing system couldn't handle 5K+ API requests/min, lacked RBAC and audit controls, and had no version history or rollback capabilities — leading to campaign errors and workflow inefficiencies.
- What I owned
- Architected the full-stack campaign platform using React.js, Redux, Node.js (Express), and Redis. Owned approval workflows, RBAC, Publish History, version diff, and rollback features.
- What changed
- Reduced API response time by 40%, cut production issues by 30%, improved workflow efficiency by 30% for 80K+ users, and reduced campaign errors by 25% across 10K+ campaigns/month.

Dentsu
Monolith to microservices migration leadership
2024 – 2025
- Context
- Led a team delivering MERN applications while the platform evolved toward more scalable and resilient architecture.
- Problem
- The existing system was slowing delivery and increasing operational risk, with testing and deployment quality needing improvement as the system grew.
- What I owned
- Led a team of 8 engineers, guided migration decisions, introduced better testing standards, and helped shape documentation and release practices.
- What changed
- Reduced downtime by 30%, lowered production bugs by 45%, and strengthened engineering consistency through reviews, API standards, and CI/CD practices.

Merkle / dentsu
Reusable commerce frontend systems
2021 – 2024
- Context
- Built storefront and platform capabilities for e-commerce teams serving multiple markets and product teams.
- Problem
- Teams needed faster feature delivery, stronger consistency across interfaces, and better confidence in complex user-facing flows.
- What I owned
- Built reusable component patterns, customized commerce frontends, implemented Cypress coverage, and mentored junior engineers on scalable React practices.
- What changed
- Improved delivery speed by 40%, reached 95% regression coverage for critical journeys, and helped reduce page-load time by around 2 seconds.

Dentsu
Internal reusable component library
2024 – 2025
- Context
- Frontend teams across Dentsu were building similar UI patterns independently, leading to inconsistent experiences and duplicated effort across projects.
- Problem
- There was no shared component system, so teams were shipping inconsistent UIs, spending time rebuilding common patterns, and struggling to maintain design coherence across products.
- What I owned
- Led the creation of a reusable component package with 50+ components — including Accordion, Data Table, Dialog, Drawer, Command, Combobox, and more — used across internal frontend systems. Collaborated with 3 teammates to build comprehensive documentation alongside the library.
- What changed
- Reduced UI development time significantly by providing ready-to-use, well-documented components. Improved design consistency across teams and established a single source of truth for frontend patterns within the organization.
