About
-
Software Engineer building scalable products across fintech, SaaS, data-intensive applications, cloud-based applications, and distributed systems.
-
Skilled in Java, Python, C#, TypeScript, React, Angular, Node.js, SQL, AWS, Docker, and Kubernetes, with experience across frontend, backend, infrastructure, and production systems.
-
Currently working at PayPal, building and optimizing payment services, APIs, data workflows, and enterprise applications.
-
Previously helped build Calenso, a SaaS scheduling platform used by 100K+* people:
- Redesigned a multilingual form system across 100+ forms, reducing new form and language development from ~2 weeks to ~2 days.
- Created in-house reusable UI libraries and shared components used throughout the application, reducing duplication and making features easier to maintain and customize.
- Built production monitoring and error-notification workflows that automatically surfaced frontend and backend failures to improve maintainability and incident response.
-
I enjoy taking ideas from design and architecture to production, solving complex problems with simple, reusable systems.
* Peak metrics recorded; actual current figures may vary.
Stack
Experience
- Developed backend RESTful APIs for payment wallet integrations, reducing database round trips from 6 to 2 by restructuring service-layer queries.
- Reduced data retrieval times by 47% for a Python, SQL, and AWS service processing 250K+ records through optimized query patterns and targeted indexing.
- Improved frontend load times by 38% for enterprise users through lazy loading, bundle splitting, and client-side performance optimizations across React applications.
- Improved deployment reliability by managing infrastructure with Terraform, containerizing services with Docker, and deploying to Kubernetes through ArgoCD.
