SaaS Platform Refactor
Led the refactoring of a monolithic legacy application into a modern microservices architecture.
The Problem
The existing platform was difficult to maintain, slow to deploy, and could not scale to meet growing customer demand. We were facing increasing technical debt and developer frustration.
The Solution
I designed and led the transition to a microservices architecture using Docker and Kubernetes. We broke down the monolith into smaller, independent services, established a robust CI/CD pipeline, and improved our monitoring and alerting systems.
Impact & Results
Reduced deployment times from weeks to hours. Improved system uptime from 99.5% to 99.99%. Enabled the team to scale services independently, leading to a 50% increase in feature development velocity.
Frontend Performance Optimization
Improved the load time and rendering performance of a high-traffic e-commerce website.
The Problem
The website's slow performance was causing a high bounce rate and negatively impacting conversion. The Lighthouse score was below 50, and the Core Web Vitals were poor.
The Solution
I conducted a performance audit using Lighthouse and WebPageTest. I implemented code splitting, lazy loading for images, and optimized the critical rendering path. I also set up a performance budget to prevent future regressions.
Impact & Results
Improved the Lighthouse performance score from 45 to 92. Reduced Largest Contentful Paint (LCP) by 2 seconds. The bounce rate decreased by 15%, and the conversion rate increased by 5%.
